How Does Lowrance Structure Scan Work?

When you’re fishing, you can waste a lot of time looking for perfect fish hiding spots. In order to take all the guesswork out of finding the perfect spot, there is a unit called a ‘fishfinder’ that uses sonar to bounce back images of what is behind and in front of your boat. By using a fishfinder or ‘sounder’ in tandem with typical fishing skills, you can increase your success and bring in more fish with every trip out to the lake or ocean.

Lowrance has created a revolutionary HDS sonar scanning system. A typical sonar module sends a three dimensional signal out frm the boat’s tranducer, but it receives an image that is reported in only two dimensions on the fishfinder display. This way, you can identify potential fish and locations where fish may be hiding. You can use this to see up to 250 feet around the boat, making fishing much more productive as you find areas where fish are more likely to be hiding.
Lowrance has developed a revolutionary add-on to their Lowrance HDS sonar systems that makes typical sonar seem obsolete. It plugs in directly to your Ethernet port and gives you a three dimensinal view of your surroundings, including 480 feet of clear, comprehensive viewing coverage.

Lowrence StructureScan has been designed to give anglers the best view of the water around or under their boat. It’s meant to be as close to photographic as possible, with precise depth and distance displays to take the questions out of sonar. With StructureScan, items underneath and around your boat look just as they should; trees and piles of stones beneath your boat look just as they would normally. That takes the guesswork out of avoiding potential obstacles that could catch your line or your boat, as well as finding potential fish-rich areas.

StructureScan technology also offers DownScan and SideScan Imaging, allowing you to see even below your boat. It prevents you from wasting valuable time looking for fish by showing their forms and shadows on the screen. It also allows you to see the area below your boat in crisp, clear, well-defined images.  TrackBack is another feature that is part of StructureScan. It actively records at all times and saves the recordings directly. This means that you can scroll through past sonar scans to see common fish hiding places or to use them as a guide to find your way back to your starting point. By avoiding areas without fish, you don’t have to waste gas and time finding great fishing spots.
You can use the StructureScan separately, if you would prefer, or you can attach it to your existing Lowrance HDS. That allows you to receive split or full-screen options to get the best view of the water below and around you. By using StructureScan in tandem with TrackBack, DownScan, and SideScan, you can get a truly 360 degree view of the water around your boat, avoiding obstacles and finding the best fishing areas. The StructureScan unit is an incredibly user-friendly unit meant to make fishing easier and more enjoyable for everyone.

What You Probably Didn’t Know About Down Imaging Sonar

Fishing is among the best experiences on the planet. Whether you engage yourself in this activity for fun of sport, or even as a job opportunity, you realize that you need a way to locate where the fish specifically are. Every fisherman, therefore, has to find a way through which to locate where there are either schools of fish, reefs, weed or even bridge pylons under the bought because if you go out fishing and you don’t have a way to locate where fish is in plenty, then it is very likely that you end up catching a limited number of fish and waste too much of your time. A quality fishfinder starts at roughly $500, but it will surely pay for itself since you reduce wasting much of your time fishing and you increase the number of the fish you get altogether.

The use of fishfinders is one of the most developed practices in fishing. A fishfinder is basically an instrument, usually termed as a sounder, that detects reflected pulses (sound energy known as SONAR) in the water and helps locate fish. In the case of the most modern fishfinders, which also have the zoom functionality, the reflected sound waves can be used to determine measurement of the object and therefore aids the fisherman in interpreting the information on the graphical display, more accurately.

There are a variety of fishfinders in the market, but the most common include both down and side imaging. Better and better ways of locating fish are being invented each day, but let us focus a little bit more on down image sonar.
So what is down imaging sonar? This is a fish-locating practice that entails the use of high-frequency sonar beams that are emitted in ultra-thin slices and meant to produce comprehensive and detailed images of what is under the boat. Note that down imaging users, just like the side imaging user, have to choose between 455 or 800khz in the settings menu so that they can get the most favorable resolution for them. The high-resolution pictures that are produced by down imaging sonar are what help anglers locate any object that the boat passes directly over. This is made possible by the use of high-frequency waves that are reflected by the object beneath the boat.

Some of the Advantages of Using Down-Imaging

1. Speed. Questioning the speed of the down imaging is very important since if the speed were very slow, let’s say half the speed of the boat, then it is very possible that very few fish or no fish will be caught at all since the images that will be displayed on the graphical screen will be something of the past. Down imaging, usually abbreviated as DI, spots impressive speeds of around 45mph. This is very necessary to the operator since it spots fish that the boat is passing directly over. One good example of a fishfinder is 2D, which is very impressive on speed, probably the reason why it is a favorite amongst most people but, DI is also very fast and unlike the traditional 2D, its images are top notch making it very reliable.

2. Unlike side imaging which gives a “fly-over” kind of images, down imaging sonar gives high quality images that seem like they had been taken from the sea bed.

Unlike side imaging that provides a 180 degrees coverage, down imaging is purely dependent on the selection its user makes. For instance, the humminbird users have three settings to choose from: “Narrow”, which covers approximately a third of the depth, “Medium”, on the other hand, covers an area that is equal to the depth while “Wide” covers 1.5 of the depth.

All the above three settings are dependent on what the user needs to do at that moment. If, for instance, he/she wants to pinpoint a specific area for cover, then “Narrow” is the most recommended. On the other hand, if the operator needs to search a larger area, then either the “Medium” and the “Wide” are simply the best.  There are weaknesses with the use of DI. The fact that fish may be shown as dashes or dots may make it very hard for the fisherman to carry out efficient fishing. It is therefore advisable then, to use two or more technologies hand in hand. The reason is because these technologies do not offer the same things. In most case, one reveals what the other is unable to show. Using them together means that you gather more information at once.

What is a Thru-Hull Sonar?

thru hullFinding fish through modern technology is a groundbreaking step in the sport. Using sonar to help find game fish and schools of bait fish allows anglers to target areas that hold larger amounts of fish.  These items are popularly known as fish finders and are much needed and appreciated by fishermen of all kinds. Among the best choices to choose from, Thru-Hull sonars take the lead. What is a Thru-Hull Sonar? This question will be answered in the following pointers.
Thru-Hull sonars and their origins.
First of all, sonar stands for Sound Navigation and Ranging and its main function is to measure distances. Modern equipment usually has a screen where the fisherman can see what lies below the boat like the bottom, structures, vegetation and of course fish. The electronic equipment was originally created to be used on submarines and nowadays they can be found in a wide array of sizes with a variety features. Since the hull is the lowest part of a ship which is usually partially submerged and below the water line then the Thru-Hull sonar is an electronic fish finder installed in this specific part of a boat or ship. It is also interesting to know that Thru hull means Hole Through Bottom. There are many benefits to be gained from this particular type of electronic devices and most of them will be mentioned next.
Thru-Hull sonars and their many benefits.
After answering the question about What is a Thru-Hull Sonar? It is of the utmost importance to understand the many benefits they provide since they are a popular option among beginners and experts alike. A subset of these benefits will be provided next:
– The device does not pick up riggers and other unusable information thereby allowing the user to focus on what’s really important and saving a considerable amount of time.
– When the boat increases its speed it does not receive air across it. This is critical for certain types of fishing activities and a favorite feature among most knowledgeable users since other types of sonars lose signal over 30 knots.
– They are more sensitive. Besides eliminating unusable noise they are also more precise and this is important in most situations where fish are not abundant.
– By design, these sonars are not affected by frequency shifts in outgoing signal caused by the hull.
– They are recommended as the best by most experts since they are suited not only to most environments, speed and weather but are also suited to be installed on a wide range of boats.

One important point is that to install a thru hull sonar requires a hole in the bottom of the boat.  That being said we recommend a professional installation.  The price to have the sonar installed by a pro is worth it, since safety is a main factor.  The performance of a thru hull compared to a transom mount aren’t comparable, since the thru hull is mounted in a perfect location free of any interference.

Ninety five percent of all fish live in just five percent of the water. By knowing this fact the obvious benefit of answering the question of What is a Thru-Hull Sonar? Has even more meaning. It goes without saying that adjusting and tuning these types of sonars is a real pleasure since they are usually made with the best quality. Since sensitivity is also known as power the user has an exact view of what is going below the boat and this is of course considered as priceless since the more power the device has the more the user will be able to see. By understanding the origins and benefits of these types of sonars a complete answer has been given to the question What is a Thru-Hull Sonar? At the end of the day the most important part is how incredibly useful it is in the pursuit of catching more fish in a smarter way.

Some Interesting Tips On Using Your Underwater Camera While Ice Fishing

fish tvAn underwater camera is a must have equipment for anyone attempting to go for an ice fishing expedition. Many people assume that these cameras are very expensive, nothing could be farther from the truth; every winter fisherman can get a camera that fits his or her budget.

Using underwater cameras for ice fishing can greatly improve a fisherman’s success rate. Which is mainly because a fishing camera allows you to see and monitor the exact surrounding and environment you are fishing in; saving you lots of time and money in the process as you can easily leave a spot that doesn’t show any potential. To make your experience with an underwater camera worthwhile and successful, there are a few tips that will come in handy, these include;

Read the manual

Many people tend to ignore this basic requirement. Make a point of going through every page, even if you have used a similar camera, remember that brands do differ. It is also recommended that you try out the camera in your bathroom or in another water body before actually going ice fishing with it.

Use the camera to scout your fishing hole

perchAn underwater camera is a wonderful scout in itself. Choose an appropriate site which you feel may fetch you some fish and place the camera at least two (2) inches under the surface of the water. Allow the water surface to settle by waiting for at least two minutes after immersing the camera. You can then go ahead to look for tell tale signs of fish around the area, even though you may not see fish at that moment in time, the camera will help you check on other signs that may point towards the presence or absence of fish, the type of fish available and the depths at which they are positioned. Signs to look for may be green seaweeds, rocks and pebbles, any present cavities etc.

Use your Camera to monitor your fishing hole

Once you have scouted for a fishing hole and drilled it, the camera can be used to monitor how the fish is reacting to your bait and help you improve your chances of catching some fish. You should measure at least some 2 feet away (depends on the specs of your camera and the type of fish you are targeting) and drill a much smaller hole that can allow your camera to fit through.

The camera should be put at the same depth as your bait and should be placed facing the dropped bait. Through the camera, you will be able to see if your targeted fish is reacting favorably to the jig movement. This allows you to effectively control the bait, or change it if necessary. It is important to hide the camera from the fish as they are naturally quite shy, to succeed in doing this, the camera should be dropped vertically.

Last winter we tried out one and got a school of 9 fish swimming around, which is pretty cool to watch.  We also had a close up of a big pike, looking at out minnows.  Both Cabelas and Fish TV make some nice underwater cameras.  Another option is using a Go Pro camera with a float.  When fishing shallow water, you can use the camera at the surface to observe and record images .

Get the right specifications

Depending on where you intend to use the underwater cameras for ice fishing, it is important that you get a camera with the correct specifications. If you will hover between freshwater and salty water bodies make sure you get a camera that can be calibrated accordingly, get a camera that can give you long hours of service before requiring a recharge. The display screen should also give you vivid clear pictures irrespective of the weather.

Dot Matrix Sonar for Ice Fishing

The Dot Matrix Sonar Fish Finder has a thermometer and an alarm and it is specially designed for fishing enthusiasts and fishermen. It is also designed to search the location of fish, bottom contour and depth of water.

Moreover, it can be mounted in various ways including; boat hull, poles, floats and ice pieces.

Sonar Technology

dot matrixThe Dot matrix sonar fish finder features sonar technology that is usually based on sound propagation in order to define and locate structure, composition and bottom contour by using the transducer. The time interval between the transmission of a single sound wave signal emitted by the transducer and reception of the specific object is also measured. This in turn helps to determine the distance of the object. The sonar fish finder also uses the received signal to interpret the size, composition and location of the detected object.  The sonar is also used for ice fishing.

The Dot matrix sonar fish finder has various features including; a large adjustable matrix LCD screen that has a LED back light, adjustable sonar sensitivity settings, determines the depth and location of fish, used on both salt and fresh water, used as a depth sounder and fish finder, displays water temperature, displays bottom contour in the sea, resists grass interference when used in the lake and zooms at a specified depth. The device also has other minor features including; a clear fish icon, battery strength indicator, selectable between feet and meter readings, sonar for ice fishing, removable float, 200 kHz sonar type frequency and a water resistant design. The The Dot matrix sonar fish finder can be mounted using various methods including; fixing it to the boat hull, using the float located on the cable to mount the sonar in the water, fixing it on a firm pole and pushing it to a desirable position in the water and cutting a hole on the surface of the ice and placing the sonar under water.

The Dot matrix sonar fish finder has various specifications including; an FSTN LCD display size of 128 x 64 Dot Matrix, round transducer sensor that has a 7.5 meter cable and a 45 degree beam angle, -20 �C to 70 �C operating temperature, 4.92′ x 2.91′ x 1.18′ inch size and 160 g item weight without including the sensor and batteries.

In terms of price and effectiveness the dot matrix delivers on both, regardless of where you are using the sonar.

How Flasher Sonar Works

flasherFor a long time now, the flasher sonar has been quite a popular item among ice anglers. This particular type of sonar unit is used to reveal objects within the water through a circular screen. For a beginner, the flasher sonar can seem to be rather complicated, even for some seasoned anglers it not always easy to use the unit to its full potential.

The best and most effective way to use the flasher sonar is to first understand how it works. The following are the steps and processes of how the flasher sonar works.

Dropping the transducer

Once this device is plugged into an turned on, it is then dropped into the ice hole. In case you have an older model of the transducer, it important that you ensure the device sits on the ice in such a way that it is either at or underneath the edge. This is because, if one fails to do so, the signal that bounces off the ice might create a clear picture. In addition, new models of the device tend to give way better readings.  The picture is of a Vexilar flasher, which is one of the top sellers in the flasher market place.  They make rugged and ice fishing specific flashers meant for cold weather.

Setting the Range

Depending on the kind of flashers one is using, one can get readings between various ranges of water depth levels. In case you have done some research in regards to mapping out the area using Smartphone, GPS or sonar unit, then it will be a bit easier to approximate how deep you are fishing. In order to attain the best reading, the bottom depth has to be set where the following deepest range setting is, in accordance to its actual depth. Lest say the depth is 25 feet, then the bottom depth should be set at 30 feet.

Adjusting the gain

Basically the gain refers to level of power that the transducer can give out. The device is responsible for the sonar signal that travels through the transducer all the way down to the bottom of the lake then back up again. The amount of gain required depends on the depth of the water. One has to start by tuning or setting the gain until there is some significant interference. From here, one has to gradually ease up on the tuning till the screen begins to clear. This is what will provide the gain together with the best indication of anything that could be in the water.

Zooming in

When it comes to the flasher sonar’s resolution, for a good resolution, one has to focus on specific areas. The zoom found on each flasher works somehow differently, so it is best that before using the flasher you read the instructions carefully.  Zooming isn’t always necessary, since an unmagnified view will give readings from the bottom to the surface.


The other thing with the flasher sonar is that, when you drop the lure down into the whole, there has to be clear visibility on the screen. A bar is what will represent the lure. The general idea is make the bar appear as thin as it can possibly be. This is done through fine tuning the gain. The reason this is done is for one to be distinguish the movements that appear on the screen. Any line that appears in between the bottom depth and the ice is most likely to be the fish.


How does a fish hawk probe work?

fish-hawk-x4A Fish Hawk probe can send data via sonar signal, and is a highly effective wireless system. Any cable can be used with the system, and the product has attracted thousands of anglers, and is becoming increasingly popular. But how does a Fish Hawk probe work? Here is a how-to-guide about Fish Hawk products.

What is the Fish Hawk probe?

Fish Hawk have produced a number of probes, include the X4 and the X4 + Depth. The Fish Hawk probe needs to be installed as a transducer on your boat, which helps the probe to function. The transducer is the piece of equipment which receives the solar signal which is sent by the probe. The probe is battery operated but can last for around 100 continuous hours on four AA-sized batteries. Depending on the amount of fishing you do, you could survive the entire season with only one set of batteries, making the Fish Hawk probe a highly durable and long lasting product. You will never have to replace the battery in the Fish Hawk TD, as it relies on a lithium battery in its internal structure, which has a shelf life of twenty years. This also increases the probe’s durability when it used under water. The TD also stores depth data and temperature data which can be viewed later on the inbuilt LCD screen once retrieved from the water.

Are Fish Hawk products easy to use?

Fish Hawk have provided products which are extremely durable and can be dropped in the water at a fast speed and still produce highly reliable and in-depth readings. The TD for instance takes a reading at a rate of nearly twenty times per second and presents all temperature data in a concise and easy-to-read manner. It can be hooked to a rod which can weigh up to 12 ounces and then can be free spooled to the bottom of the water. Fish Hawk products have a highly accurate sensor inbuilt with provides highly reliable readings. In addition, your depth finder will not interfere with this piece of equipment, as they run at an approximate 200 KHz, meaning the fish hawk probe will not pick up on any interference, even in the transducers are installed side by side. If you are in possession of a dual beam type of transducer, you can mount the Fish Hawk X4 as far as you can from it as is practical, and the products work on all type of boats, no matter their shape, size or material.

Where can I purchase products made by Fish Hawk?

There are several retail outlets which stock these type of products. All products are designed and manufactured in the United States, and are easy to assemble, as well as being highly effective, reliable and durable. Items can also be shipped across the country or even further afield. The Fish Hawk X4 probe can be used in water as deep as 300 feet, even though the gain setting may have to be increased slightly to get an accurate reading at over 200 feet deep. It has even be noted that the product has made readings in waters over 400 feet deep. The Fish Hawk TD can read up to around 300 feet deep in water.

History of Hummingbird Fishfinders

Humminbird Fishfinders are a giant in the world of fishing and water navigation systems, but it has humble roots. In 1971, in Alabama, a group of local investors partnered and funded Techsonic Industries, which was then known as Fulton Electronics. It worked with Heath kits, and modified them to come up with fish-finding equipment. The work area was quite small and production capacity was limited due to resource shortage. The fish-finding equipment that was sold then was known as the Humminbird Depth Sounders.

In 1975, Fulton Electronics made a depth sounder that was waterproof, a pioneer in its own regard. Every fisherman worth their salt was scrambling to purchase it. To date, it has been one of the best-selling fish-finding equipment. It is at this time that the company came under new management and changed its name to Techsohummin_edited-1nic Industries.

In 1984, the LCR series of displays was introduced. It changed the world of fish-finding since the screens were much clearer. This paved the way for the LCD displays that are in fish-finding equipment nowadays. This technology was used in the LCR4ID Fishfinder, which upon its inception in 1987, became the most popular fishing product in both leisure fishing and industrial fishing purposes.

In the 1990s, all manner of innovations were spread out by the Humminbird brand. One of the most popular inventions was the 3D sonar, which enabled the user to get accurate clear images of the seabed using sonar imaging. This growing success was so great that it caught the attention of many industry giants. One of the companies to notice the potential was Teleflex Incorporated, from Pennsylvania. It joined hands with Techsonic to come up with the Humminbird WIDE range. This was a match made in heaven as the WIDE series of equipment is famed to be the finest product launch in the company’s history.

Also, in 2003, there was the launch of Matrix Fishing Systems. This provided a very high level sonar location programs and chart plotting possibilities. Another thing that revolutionized the market at this stage was the GPS capability. It was very helpful as it threw out the system of using old fashioned compasses. Wherever a fishing boat was, the sailor could navigate their way to the deep waters and back to shore with the greatest of ease.

2004 saw Techsonic Industries become a subsidiary of Johnson Outdoors. Johnson Outdoors is a company that has made a niche for itself in the world of inventions. With its greatness, and the absolute genius that is part of Techsonic Industries, it is bound to take the world of fish location equipment by storm.

If the past achievements are anything to go by, the future of Humminbird Fishfinder is really bright. With its dedicated team of experts working hard to come up with new products, there is the assurance of quality, not forgetting the loyal customers, who keep buying the products. The goal of Humminbird Fishfinder is to be the only choice for fishing, and to supply unique and high quality equipment for fishing activities, be it for commercial purposes or for leisure fishing.

History of Garmin Fish Finders

61jT5xNafOL._SL1000_In order to understand and appreciate the history of Garmin fish finders, we must first take a look at Garmin the company.

Garmin Ltd was founded back in 1989 by Min Kao and Gary Burrell. It is the parent company of several groups of companies. Garmin deals in the production of marine, aviation and consumer technologies associated with Global Positioning Systems. Garmin International, which is a subsidiary company, acts the headquarters of Garmin Ltd. It is located in Olathe, Kansas. The company’s largest operating and production subsidiary company is Garmin Corporation, which is located in Asia.

Over the years, Garmin products have come to be widely known. Nearly everyone who relies on a GPS system has heard of Garmin. They currently provide the best devices that ensure people working in various fields do not get lost and are able to reach their intended destination on time.

For those who regularly go on fishing trips, Garmin fish finders have become a trusted product. In regards to fish finding products, Garmin fish finders are some of the most accurate and straightforward fish finders out there.

Garmin fish finders employ the use of quite a unique system called UltraScroll. This system enables the user to receive top quality readings at very high speeds. According to reports from various fishermen, Garmin fish finders managed to give them accurate readings at speeds of almost 30 knots.

When fishermen are travelling at high speeds on the water, their Garmin fish finders can still be able to give them a clear reading on the bottom structures, which makes these devices ideal for locating fish that could be probably at the bottom.  Another use is finding bait fish in open water, which requires covering alot of ground, being able to cover more water allows you to find more fish.

There are several types of Garmin fish finders, some of the most commonly used and widely known include:

The Garmin Echo 200 fish finder

This particular Garmin fish finder is one of the earlier versions, but that is not to say it is ineffective. On the contrary, it is quite effective. Most fishermen have referred to using this fish finder as having eyes beneath the waters. Its transmission power is 300w of RMS, which is paired with double frequencies of 77 and 200 kHz. With this device, one is able to have a clear view of the water down to 1000 feet in cases when using in fresh water. However, in salty water, the readings can be a little shallow, reaching a depth of maybe 500 feet.

The devices have HD technology that eliminates all guesswork related with the interpretation of complex fish echoes or arches. They use a highly powerful software system that helps to ascertain, which echoes are most probably those of fish. After evaluating this information, the fish finder then displays them on its screen. This particular Garmin fish finder makes a great tool for beginners in the world of fish finding.

The Garmin Echo 550c

This Garmin fish finder has set a very high standard for anglers who would like to improve on their fishing. The device is user friendly, starting from the way it is set up to the way it is operated. Its installation process, put together with the transom mount transducer happens in just several minutes. The mount is designed as a quick release. Even though it is highly advanced, a beginner can still use it. It has an easy to use interface and user friendly menu.

The other brands that came along in between this two are the Garmin Echo 100 and the Garmin Echo 300c.
