A GPS is a must have for many fishers and having it in one unit with a fish detector is economical, space saving and convenient. Having the addition of a GPS gives you many benefits. It will give you the ability to mark hot fishing spots and easily return to them in the future, as you can mark the spot on the GPS and then track your way back to it later. These spots are called waypoints and on most units you will be able to mark hundreds or even thousands of them.

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]
Thru-hull: This means a threaded bronze, nylon or stainless steel shaft passes through the bottom surface of the hull. You have several styles to choose from: external football-shaped head with water flow smoothed by a fairing block that also corrects for the dead rise (sideways slope of the hull); or round mushroom head thru-hulls, either semi-flush or flush mounted. These are the most challenging to install, but likely to provide the best signal quality. Displacement power and sailboats generally use thru-hulls.
Fish will show up on your screen as an arch (the reason why they are shown as an arch is explained in detail here). But it’s important to remember these arches can vary in size (length and width), and might not be a full arch – look out for those half arches too. The screenshot below gives some nice examples of different arches. They vary in length and width, and some are not full arches, but these are all fish.

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.
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.

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.
The image above, at right, clearly shows the bottom structure—plants, sediments and hard bottom are discernible on sonar plots of sufficiently high power and appropriate frequency. Slightly more than halfway up from the bottom to the left of the screen centre and about a third away from the left side, this image is also displaying a fish – a light spot just to the right of a 'glare' splash from the camera's flashbulb. The X-axis of the image represents time, oldest (and behind the soundhead) to the left, most recent bottom (and current location) on the right; thus the fish is now well behind the transducer, and the vessel is now passing over a dip in the ocean floor or has just left it behind. The resulting distortion depends on both the speed of the vessel and how often the image is updated by the echo sounder.
The size of the area you’re scanning will be affected by the angle of the cone. A wide beam cone scans between 40°-60°, meaning you’ll be covering a large area. A narrow cone will scan between 10°-20°. So make sure you’re aware of whether your fish finder is using a wide or narrow cone when you’re looking at the data on your screen. The Deeper PRO and PRO+ have wide and narrow beam scanning (55° and 15°), the Deeper START has a medium/wide beam (40°). One other point to remember about how you sonar works is that it is constantly sending and receiving data, which means your display will be continually scrolling. The current scanning data will be on the right – the further left on the screen, the older the data.
Fish will show up on your screen as an arch (the reason why they are shown as an arch is explained in detail here). But it’s important to remember these arches can vary in size (length and width), and might not be a full arch – look out for those half arches too. The screenshot below gives some nice examples of different arches. They vary in length and width, and some are not full arches, but these are all fish.
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.
In summer and winter, water temperature is very important - these units will help you discover areas that should be comfortable for your target species. Safety is found in structure, for prey and predator alike. The illusion of safety for baitfish equates to food for prey. So locating proper structure is certainly important. It's been said that 90% of the fish can be found in 10% of the water. Believe it. If you're fishing structure in the middle of a lake or a man-made reef, knowing what's below you is important. Now you know.
Transmit Power: Transmit power is expressed in watts RMS (root mean squared) and is 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.
Another great feature of the Elite-5X HDI is the Downscan Overlay that combines traditional sonar with Downscan. Downscan’s primary purpose is finding structure, but it can’t very accurately spot individual fish. That is better done by sonar. Combining the two in one, this device displays on one screen both bottom and structure. So you can see every rock and submerged object as well as fish.
You have been anxiously awaiting the arrival of the weekend so that you can pack up and hit your favorite fishing area.

The Hummingbird fish finder can easily be attached to any surface on your boat and can aid you in discovering where the fish are hanging out. If you do not enjoy fishing yourself, but are looking for something to get the outdoorsman in your life, a portable fish finder is a perfect gift and sure to bring a smile. Shop easily online, check out convenient shipping options, and reel in an amazing deal on the perfect fish finder.
When checking the transducer, the most important feature is the cone angle. For a bigger perspective of the verges underneath, choose a bigger degree on the cone. The wider beam gives more coverage of the under water and allows locating more fish within it. However, its drawback is the quick loss of strength. Due to this, it cannot penetrate the water as deep as the narrow cone. The narrow one can go really deep even in shallow waters and can also give information on the composition of the bottom.

Ice fishing is work. Just to get a line wet, you’ve got to drill and scoop. Just to keep a line wet, you’ve got to clear ice from the guides. There are a ton of little things that can make a hard-water outing much more challenging than fishing on a sunny summer afternoon, so it should be no surprise that smart ice anglers have come up with a pile of gear hacks to make any day on a frozen lake a little easier, more comfortable, and a lot fishier. You could fill a book with these tricks, but here are four that every serious ice fisherman should know. They all require a few inexpensive items you probably have lying around at home.


MOUNTING THE FISHFINDER: Cockpit space in any paddle craft is premium real estate, so definitely do some planning before you do some drilling. The carpenters pencil is your friend in this case. I suggest that before you drill/cut, you spend some time on the water and use that pencil to mark up potential mounting spots. You have to be able to see it well and to reach it, but it needs to be out of the way when you cast, land a fish, or get in/out of your boat. If your boat has some sort of console, that's an obvious mounting choice. But, if you don't then Ram Mounts offers a number of multi-position solutions that will allow you to mount it just about anywhere. Once you decide where it will go, you have to get the wiring to the battery and to the transducer.
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.
Overall, if you want to get the best fish finder, then our top pick has to be either the Humminbird Helix 7 or the Garmin Striker 7SV. We love the large screens and comprehensive functions that you get with both devices, as well as the rugged dependability. If you want to save money, though, the Garmin Striker 4cv will be your next best bet as it comes with high-performance results, even with a smaller screen.
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.
Pinpoint your favorite waypoints and track fish with a fishfinder from Academy Sports + Outdoors. With a detailed black-and white LCD display, you can clearly spot fish as deep as 1,000' as well as track their location with depth finder technology. Water temperature sensors allow you to monitor the biological patterns of prospective catches, letting you pinpoint where they'll be at any time of day. With a waterproof casing, our selection of fishfinders are designed for use on boats or kayaks. Our giant boating and marine shop has an assortment of marine electronics from popular brands, like Humminbird, Garmin marine and Lowrance, can help you reel in the largest catch. Receive notifications for certain depths and types of fish, as well as sonar and mapping software, so you can find exactly what you're looking for.
Fish finders are incredibly valuable tools, and the more you learn about how to read them, the more successful your fishing trips will be. A key part of learning as angler is to go from trial and error to a more knowledge-based approach. Maybe you regularly catch at a certain spot with a certain presentation – but do you know why? A fish finder will help you understand not just your failures, but also your successes. And once you know this, you can recreate this success more easily.
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.
Moreover, the 7SV also has a built in Garmin GPS that allows you to make your own waypoint maps, which makes marking all those stumps, docks, and brush piles as easy as clicking a button or two. All map information is transferrable to other Garmin fish finder devices if you upgrade as well, adding even more versatility to the 7SV. Additionally, the 7SV also has its own rechargeable battery pack that helps you stay on the water all day long, thereby increasing your chances of finally reeling in that trophy catch you’ve been looking for all these years.

Although this unit lacks some of the features found in similar units from different manufacturers, it counterbalances with powerful sonar, using CHIRP for both down view and classic imaging. Additionally, it also comes with Wi-Fi connectivity, and you can benefit from a larger view if linked to a bigger tablet. It's a unit with a tremendous quality and price ratio, with a rating of four and five stars.
These sonar reflections will also display on the screen. So this way a fishfinder reads and lets you view the bottom and everything it encounters in between. The angle of the sonar beam is measured in degrees and it’s called the cone angle. A wider angle covers more area underwater. Different fish detector models come with different cone angles. Some models also include multi-beam sonar technology that allows covering a much wider area.

A fish hook is a device for catching fish either by impaling them in the mouth or, more rarely, by snagging the body of the fish. Fish hooks have been employed for millennia by anglers to catch fresh and saltwater fish. Early hooks were made from the upper bills of eagles and from bones, shells, horns and thorns of plants (Parker 2002). In 2005, the fish hook was chosen by Forbes as one of the top twenty tools in the history of man.[2] Fish hooks are normally attached to some form of line or lure device which connects the caught fish to the angler. There is an enormous variety of fish hooks. Sizes, designs, shapes, and materials are all variable depending on the intended purpose of the hook. They are manufactured for a range of purposes from general fishing to extremely limited and specialized applications. Fish hooks are designed to hold various types of artificial, processed, dead or live baits (bait fishing); to act as the foundation for artificial representations of fish prey (fly fishing); or to be attached to or integrated into other devices that represent fish prey (lure fishing).
