This unit has a colorful and compact 3.5 inch color screen that is fully equipped with a Garmin high-sensitivity GPS and Garmin’s very own Sonar, which uses Garmin CHIRP ClearVu Scanning. This GPS gives you the ability to mark your favorite hotspots and fishing areas, docks, and slipways, while using high-speed data technology to display any information that you may need, immediately on the screen.

Spend more time catching fish and less time trying to find where they are hiding with the Helix 7 CHIRP GPS G2 Fish finder. Using side-by-side dual imaging technology, this fish finder not only lets you map structures and schools, but also allows you to view both CHIRP Down Imaging and Switchfire Sonar data at the same time, providing the most complete image of the underwater environment possible. In addition to the large 16-bit display, the Helix 7 also features an integrated GPS that store up to 2500 waypoints and 50 routes so you can mark the coordinates of all the best fishing spots on your favorite lakes and rivers.
Standalone fishfinder: If you just want to see what’s below, dedicated fishfinders give the biggest display and the most performance for the least cost. If you have a small boat that you use for fishing small inland lakes or are on a limited budget, a standalone fishfinder is for you. Conversely, if your pilothouse has room for multiple displays, or if you just bought a new GPS, get a serious big-screen fishfinder. You can usually add a GPS sensor later to many units, turning them into chartplotter combos.
Other devices which are widely used as bite indicators are floats which float in the water, and dart about if a fish bites, and quiver tips which are mounted onto the tip of the fishing rod. Bite alarms are electronic devices which bleep when a fish tugs a fishing line. Whereas floats and quiver tips are used as visual bite detectors, bite alarms are audible bite detectors.

Networked system: Fully networked systems are available from all the major suppliers, and usually will support a huge range of data sources including radar, raster and vector GPS charts, video, and SiriusXM satellite radio. Many allow Bluetooth/WiFi, and you can control them from your iPhone or Android smartphone. Your fishfinder, often an external “black box” module, is just one of these sources of data. Multiple-display network systems are great for medium-sized or large vessels. Capabilities get more amazing every year.
BUT DOES A FISHFINDER REALLY FIND FISH? Does a woodchuck really chuck wood? Sorry jackwagon, I had to go there. A fishfinder works on the same theory as deep space telescopes identifying distant stars. It doesn't see "fish" but it does see things that don't look like water. Once the data is processed, the resulting image is therefore labeled fish. Therefore, these units absolutely process the data and tell you if fish are in the beam. But alas, they don't know what they're eating, or if they're even in the mood to eat. But, I do believe that fish will almost always eat if given the right offering. But, you have to find them first.
Furthermore, Garmin’s fish finder also has a built-in CHIRP continuous sweep sonar that provides the widest range of sonar profile information available, allowing you to find and mark where the fish like to hide more accurately. Best of all though, the transducer on the 7SV offers “sideview” sonar for a clearer picture of what is around you and your boat while you are out on the water.
A fish finder is an incredible tool that can help take your sport or commercial fishing venture to the next level. However, even the best fish finders can use a little improvement – and adding a GPS is one way to do this.The best fishfinder GPS combo will help you navigate whatever body of water you are on at the same time as it allows you to find where to fish more quickly, accurately and efficiently.

Having a GPS onboard is something I've wanted for a while, so that makes the Humminbird 385CI a powerful combo to me. I love "jungle fishing", getting back in mangroves and other areas that are loaded with structure. It's also easy to get turned around in those areas because if you're concentrating on fishing it's easy to lose track of where you are, where you've been, and how to get back to the launch. Obviously, this will help. Between having built in navigational charts and doing your own recon concerning tides for the day, you can make better choices as to where you want to fish.
Look for equipment that will work with multiple frequency: higher for better detail but not as successful in deep water; lower for depth but less detail on your viewing screen. Of course, if you fish only in shallow water, you’ll be happier with high-frequency output. For deep-water work and for commercial fishing, you may want to use a lower frequency.

Choosing the perfect fish finder for your requirement is hard with many features such as imaging, power and more. The main purpose of a fish finder is to catch more fish with the screen displaying the fish and underwater structure and physical objects. Other information such as water temperature and depth are common on the majority of devices with many high end fish finders providing much more.
The temperature and pressure sensitivity capability of fish finder units allow one to identify the exact location of the fish in the water by the use of a temperature gauge.Functionality present in many modern fish finders also have track back capabilities in order to check the changes in movement in order to switch position and location whilst fishing.

The intensity of the sonar return from a hard bottom will be different to one from a hard bottom. Your fish finder uses colour to show this difference. In the standard colour palette of the Deeper display, the colour varies from dull brown (softest) to intense orange (hardest). In the day mode colour palette (see screen shot), the difference is even easier to see, with the colour ranging from purple (softest) to red to orange to yellow (hardest).


It’s no secret that HDS displays are used by more tournament fishing pros than all other fishfinding brands combined, so we didn’t have to go back to the drawing board to build it; we just made the best fishfinder/chartplotter in the world even better. HDS LIVE  delivers premium performance and support for the best collection of innovative sonar features available – from Active Imaging™, StructureScan® 3D, FishReveal™ and LiveSight™ sonar, to exciting navigation functionality like C-MAP® Genesis Live mapping – all designed to help you find more fish.
Raymarine has a few units that come with a built in GPS. The Dragonfly 4Pro, Dragonfly 5Pro, and Dragonfly 7Pro all have built in GPS. Pay close attention to the unit you are buying, because if you are looking for built in GPS the standard Dragonfly 4 and Dragonfly 5DVS do not have that feature built in. You absolutely have to go Pro to make sure you get the GPS you’re looking for.
WIRING: It's like Christmas lights … once you get a good power source you can really go crazy. I guess that's one of the reasons I've never added a power grid to one of my boats. Sure as I do, I'll have dash lights, bow/stern lights, and an 18" subwoofer (though a pair of 10's would probably work just as well). Once you are set up with a 12 volt system, anything that will connect on a go-boat will now connect in your row-boat. Those are scary possibilities indeed. You'll need to keep the battery stationary, as dry as possible, and make it easy to get at for removal and recharging. The easiest choice would be to mount it in the front hatch area. The battery is actually pretty small, so you won't need a lot of room.

Humminbird 140C Fishin’ Buddy is one of the top rated fish finders among the portable type. So you can use it on your boat, on the leased boat, on the dock or for fishing from anywhere else. To use the device you won’t need to do any rigging or wiring. Instead it uses extendable transducer tube housing with the length suitable for most small and mid-sized boats.

For those who want the ultimate in fish finding technology, we have the Lowrance HDS-9 as a top rated fish finder. Not only do you get a large screen, but it’s touch activated for even more convenience. It’s so wide that you can chart two maps at once, and it’s all high-definition which allows you to create 3D models of the bottom of any lake or river in real time. Overall, this is as good as it gets.
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.
The colour on your display is crucial here for identifying a brush and logs. Because they will send a different frequency of sonar return, your fish finder will show them in a different color to the bottom (otherwise, it will just look like a hump). So make sure you choose a color palette that will highlight this difference. In the Deeper App, choose either the Classic color mode (where brush and logs will show green, like vegetation) or the Day color mode (where they will show purple).
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.

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 side scan will scan much more around the boat but are not as effective, especially in deep water. For this reason alone, you may feel the need to buy two seperate fish finders but some premium models have both side and down scanning capabilities. This means you can usually view both at the same time for a very detailed scan around the boat in all directions.

When compared to other finders, this screen is relatively small, but it still gets the job done. Since it’s in full color and has high contrast, you can still see everything quite clearly. The only downside is that you have to switch between menus, which can be a problem if you are trying to find fish and mark your location. Overall, it’s not necessarily a deal breaker, but it may be enough to warrant a larger screen. Fortunately, the Striker can come in bigger sizes if you want to upgrade.


Do you prefer having more detailed and high-contrast visuals on your fishfinder? Color LCD options from Academy Sports + Outdoors can ensure you don't miss a single catch. With higher-quality screens, you can zoom into specific sections of the water and even target specific fish. With additional sensors, our collection of marine GPS can track the movement of fish in real time, allowing you to trail and snag them before they swim away. Academy also carries portable fishfinders as well as castable fishfinders which are great for kayak, surf or bank fishing.
The power of a fishfinder—the strength of the “ping”—is expressed in watts RMS (root mean squared). Power is directly related to how well you see in silt-laden water, view down to greater depths, and successfully resolve separate targets and bottom structure. A 500-watt (RMS) fishfinder should have plenty of power for most coastal applications. Serious bluewater anglers should look for 1,000 watts or more. Inland lake fishermen can see the shallow bottom with only 200 watts.
Fish finders were derived from fathometers, active sonar instruments used for navigation and safety to determine the depth of water.[1] The fathom is a unit of water depth, from which the instrument gets its name. The fathometer is an echo sounding system for measurement of water depth. A fathometer will display water depth and can make an automatic permanent record of measurements. Since both fathometers and fishfinders work the same way, and use similar frequencies and can detect both the bottom and fish, the instruments have merged.[2]

Depending on where you fish, sometimes the difference between finding a hot channel where you can always count on the fish to return during a certain time of day and absolutely nothing can be just a few feet. If you’ve ever fished for walleye, you know what it’s like to find those feeding channels or to have the days where you just can’t quite make it work.
