The most common mistake anglers make when reading their fish finder is thinking that a long arch means a big fish. This is not the case. On your sonar display, you should think of length as representing time. For example, imagine you keep your fish finder stationary in the water (in other words you are not reeling or trolling it). If there is a fish underneath that is also stationary, what will you see on your fish finder display? You will see one continuous line. That doesn’t mean there’s a blue whale stranded in the pond you’re fishing. It means there is a stationary fish under your fish finder, and it might be a very small one.
There is not much that is more relaxing than spending a beautiful day out fishing in your boat. One thing that may make the day even better is a fish finder GPS, so you do not go home without some delicious fish for dinner. On eBay, reliable sellers offer a broad range of new and used fish finders for you to choose from, including brands like Garmin, Lowrance, Eagle, and Hummingbird. With your new color GPS fish finder, you can enjoy a full color display, along with features that may include screenshots, fish and depth alarms, zoom, and dual imaging. The Garmin 546S Marine GPS find finder, for example, features a chart plotter, sonar, an anchor alarm, sunrise and sunset calculator, and marine cartography software included. No matter which fish finder GPS you decide upon, feel confident that you are receiving high-quality products and convenient shipping options that will ensure that your order makes it to you quickly.
A GPS also gives you navigation through the waters. For this you will need to select a unit that comes with background maps and charts. One more benefit of the addition of the GPS is safety. Wherever you fish, you will have the confidence that at the end of the day the GPS will easily point you home. For example, you could be fishing throughout different locations during the day, or you could lose sight of land, or some severe weather could suddenly roll out. In such situations, a GPS will give you the exact direction to your home and will tell you how far it is.
For precise detection of structures and fish, our Raymarine radar bundle gives you remarkable resolution. The Garmin Chartplotter radar combo updates your position 10 times per second to accurately maintain your heading. A large screen with an outstanding LED display on our Humminbird fish finder GPS provides images that are easy to read even in bright sunny conditions.

CHIRP devices can transmit simultaneously on high and low frequencies. The lower frequency gives greater depth penetration, and it requires less power than a higher frequency signal so it generates less noise. The result is a “whisper into the water” that locates the fish without disturbing them. The higher frequency signal gives even finer detail at shallow to mid-water depths.
Many people prefer to fish solely with lures, which are artificial baits designed to entice fish to strike. The artificial bait angler uses a man-made lure that may or may not represent prey. The lure may require a specialised presentation to impart an enticing action as, for example, in fly fishing. Recently, electronic lures have been developed to attract fish. Anglers have also begun using plastic bait. A common way to fish a soft plastic worm is the Texas rig.
Ultrasound frequency used by a fish finder generally ranges from 15 kHz to 200 kHz. However, the majority of the conventional fish finders oriented for recreational craft utilize 50 kHz and 200 kHz. Such fish finders available in the market incorporate electronic circuitry that can transmit and receive ultrasound in these two frequencies. Also, a transducer mounted on the bottom of the craft is configured to handle these two frequencies.
Kiss has collectable action figures. Does Madonna have action figures? Eh, better not answer that one. Back in the day, I was a member of the Kiss Army. What sort of fan club does Madonna have? Better step away from that one too. Pluto will always be a planet to me, and Kiss is already in *my* rock and roll hall of fame. I love the smell of flamethrowers and flash pots in the morning … smells like … victory.
These are very valuable features to target for a range of species, and the good news is, they are easy to spot with a fish finder. As you troll or reel in your device, you will see the depth contour change – don’t forget to use the depth reader on your display (on the Deeper App it’s in the top right corner of the screen) so you can track how quickly the depth is rising or falling.

Simrad’s GO9 XSE Combination GPS/ Fishfinder offers a networkable 9” Touchscreen unit at an affordable price point.

As we mentioned, the strength of a fish finder is in how well it can locate the fish, which is why you need a high-quality transducer. CHIRP technology is one of the best you can find, and it provides a 200-watt RMS signal that can reach down to 1,600 feet in fresh water and 750 feet in salt water. Overall, you can find plenty of fish with this device.
More pixels per square inch will provide better detail of structures, a better representation of what’s below you, and improved split-screen images. More pixels—higher screen resolution and a big screen—allow you to see the air bladders of smaller fish, see fish near the bottom, separate closely spaced targets from one another, and to see fish on the edges of “bait balls.” But remember: the contrast of the display must also be sharp in order to use the resolution. Like many features, you get what you pay for with display resolution—the more the better.
Eventually, CRTs were married with a fathometer for commercial fishing and the fishfinder was born. With the advent of large LCD arrays, the high power requirements of a CRT gave way to the LCD in the early 1990s and fishfinding fathometers reached the sporting markets. Nowadays, many fishfinders available for hobby fishers have color LCD screens, built-in GPS, charting capabilities, and come bundled with transducers.[5] Today, sporting fishfinders lack only the permanent record of the big ship navigational fathometer, and that is available in high end units that can use the ubiquitous computer to store that record as well.
Higher frequency transducers have shorter wavelengths and more wave cycles per second, which means you can visualize more details (smaller fish) but have only shallow to moderate depth capacity. One sound wave at 200kHz is slightly longer than 1/4", so a 200kHz sound wave will be able to detect fish as short as a quarter of an inch. A 200kHz transducer has a range of only about 600'. High frequency provides a crisp, clear picture of the bottom with the tradeoff of less depth range. For best resolution, choose 800kHz or 455kHz transducers.

How to choose a fish finder? There are so many fish finder brands and models of fish locators available that it can be quite difficult to figure out which one would best meet your needs and your individual fishing style. Moreover, it’s also easy to get lost in transducers, echoes, sonar, flashers and transom mounts. The most important thing to keep in mind when choosing a good fish finder is the question: will it help you to catch more fish? To make this choosing process less complicated and so you can understand more about fish detector features we have compiled this buying guide. Using this information will help you to make the best choice.
Transducers: Fishfinders operate using a single frequency transducer, dual frequencies, multiple frequencies or a broadband CHIRP system. In general, higher frequencies give the finest detail resolution, the least background noise on your screen and the best view from a fast-moving boat, but don’t penetrate as deeply as lower frequencies. Shallow-water inland anglers generally choose higher frequencies of 200kHz, 455kHz or 800kHz. For maximum depth, use lower frequencies. We recommend 200kHz or higher (up to 800kHz) for water depths up to 200' and 80kHz or 50kHz for deeper waters.

These units are battery operated and the signal is transmitted back to the receiver. So, don't expect a lot of range or HD resolution. But, if you simply want to know how deep the water is ahead of you so that you can make better choices, this is it. For me, I would need to cast it with a rod/reel loaded with heavy braid. The areas I'd likely cast to would hopefully hold big snook and in the spring they love this color. I don't want the "dog ate my homework" story to become the "snook ate my transducer" story.

A compact, affordable combination GPS/Fishfinder. Simrad’s GO 5XSE is an all in one solution to quality chartplotting and sonar. The included Med/High/DownScan transducer provides exceptional sonar imaging in near-photo like detail. Multiple Charting options from Insight, Navionics and C-Map enable the Simrad GO5 to go anywhere the water takes you.
The depth scale on the right of the screen enables you to identify the depth of any features you find. The depth reading in the top right of the screen shows you the bottom depth under your fish finder right now – bear in mind this is not necessarily the same depth as the features you have just scanned, especially if you are scanning drop offs or points.

Your fishfinder needs to accomplish two objectives: find the fish and help you record where they like to hide at your favorite fishing spot. In both respects, Garmin’s Striker 7SV definitely delivers the goods and then some. This superior scanning sonar gives one of the most complete images available of what is in the water around you and how deep the fish are hiding in real time with near-photographic detail. In terms of an easy to use interface, this model uses dedicated navigation and function buttons to provide reliable responses for more intuitive operation even by novice users.

The display is all about pixels. With more pixels you will be able to see more details, so it’s also an important factor to consider. More pixels also means higher price of the fish detector. We would suggest going minimum 240(v) x 160(h) pixels of the screen. However, this screen will give a pretty blocky image. To have a sharper image and better resolution, you will need to invest more.
We’re only slightly kidding when we say that one of the simplest ways to pick a transducer is to decide just how big of a hole you want to drill in your boat. Fishfinders intended for the small-boat, freshwater angler often come with a transducer, usually a transom-mount type. But many transducers are purchased separately and need to be installed through the hull.
