The 256 color TFT screen gives a clear image that can give you readings of depths of up to 240 ft. The charge of the unit can last up to 30 hours. It features SideFinding sonar that gives accurate readings. Its benefit is that you can point it in any direction and get full coverage of the area to find more fish. The temperature feature is included.
The term tackle, with the meaning "apparatus for fishing", has been in use from 1398 AD.[1] Fishing tackle is also called fishing gear. However the term fishing gear is more usually used in the context of commercial fishing, whereas fishing tackle is more often used in the context of recreational fishing. This article covers equipment used by recreational anglers.

Big baits catch big fish, but this presents a problem for the ice angler. Hunting behemoth pike and muskies requires large, lively baits that do not play nice with tip-ups. Suckers and live trout are strong enough to trip the flag of almost any tip-up, causing you to waste time resetting lines after false alarms. Attaching a planer board clip to your tip-up to hold your main line will prevent even an 18-inch sucker from triggering a false flag. The added pressure of the clip, which can be adjusted, has enough tension to hold suckers and trout but still allow predators to pull the line free and run. The flag will trip when it matters, but the bait won’t have the strength to trip it by itself. Just snap the clip to the line guide of the tip-up under the spool. This will allow the planer board clip to hang freely under the water. Simply clip in the main line after setting the bait.

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.
Unless you are an experienced fishermen, you will only use one type of beam in order to find fish. A wide beam transducer covers a large area but provides less bottom detail and often has a less powerful frequency of around 50 kHz. Narrow beam covers less underwater but provide more detail and bottom definition from the additional frequency around 200 kHz.
For deep-water fishermen, and those who spend much of their time angling in open water, a GPS is essential. When you are far from landmarks and familiar sight-lines, your chances of success can be much better when you can return to that favourite spot. Commercial-fishing pros understand this as well as anyone, which is why they invest in quality GPS equipment.
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.

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.
Commercial and naval fathometers of yesteryear used a strip chart recorder where an advancing roll of paper was marked by a stylus to make a permanent copy of the depth, usually with some means of also recording time (Each mark or time 'tic' is proportional to distance traveled) so that the strip charts could be readily compared to navigation charts and maneuvering logs (speed changes). Much of the world's ocean depths have been mapped using such recording strips. Fathometers of this type usually offered multiple (chart advance) speed settings, and sometimes, multiple frequencies as well. (Deep Ocean—Low Frequency carries better, Shallows—high frequency shows smaller structures (like fish, submerged reefs, wrecks, or other bottom composition features of interest.) At high frequency settings, high chart speeds, such fathometers give a picture of the bottom and any intervening large or schooling fish that can be related to position. Fathometers of the constant recording type are still mandated for all large vessels (100+ tons displacement) in restricted waters (i.e. generally, within 15 miles (24 km) of land).

Inland fishfinding has changed, with high-frequency (455 or 800kHz) transducers that look to the side, straight down or can aim over a 360-degree range. Fishfinder manufacturers offer the inland angler a growing (and often confusing) assortment of choices in frequencies, beamwidths, even the underwater direction you can look. Inland anglers who search for fish in shallow lakes don’t need the power to see down to 5,000', but can gain a big advantage by looking out to the sides, so Garmin, Raymarine and Lowrance have products using multi-beam transducers for that purpose. Here’s where the Marketing Jargon takes over, with names like StructureScan HD™ and CHIRP DownVision.


Fishfinders allow anglers to see a graphic representation of what is beneath their boats so they can identify fish. To choose a fishfinder, consider the type of unit—whether it includes GPS and is part of a boatwide network, size of the fishfinder’s footprint, resolution of the display, how much transmitting power you need, and what frequencies will work best in the inland, coastal or deep-water environment where you fish.
With the Fish Symbol feature disabled, an angler can learn to distinguish between fish, vegetation, schools of baitfish or forage fish, debris, etc. Fish will usually appear on the screen as an arch. This is because the distance between the fish and the transducer changes as the boat passes over the fish (or the fish swims under the boat). When the fish enters the leading edge of the sonar beam, a display pixel is turned on. As the fish swims toward the centre of the beam, the distance to the fish decreases, turning on pixels at shallower depths. When the fish swims directly under the transducer, it is closer to the boat so the stronger signal shows a thicker line. As the fish swims away from the transducer, the distance increases, which shows as progressively deeper pixels.

It terms of the functionality, the HDS-7 is able to connect to the internet to broadcast data, update to new software, upload information such as marked coordinates and more. This Lowrance model uses the latest of advanced technologies such as CHIRP sonar, Broadband sounder, StructureScan HD, DownScan imaging and Trackback view for the ultimate fish finding experience.
Fish icons are a useful tool when you are getting started with a sonar device: your fish finder interprets the sonar data it receives and tries to work out if it is a fish or not. It does this based on factors like the size of the object and the strength of the sonar return. In the case of Deeper sonars, we use an advanced algorithm in the Deeper App to interpret the data. Unfortunately, even the most advanced units aren’t 100% accurate in interpreting correctly.
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.

It’s often been said that the act of fishing isn’t actually about catching a fish. Rather, it’s about a quiet moment with nature and a chance to sit, think and relax, whether on your bass fishing boat or on the banks of a river. Of course, if you’re a sport fisherman reeling in that prize monster on a white-capped ocean, there isn’t much relaxation to be had. If you prefer ice fishing or fly fishing, shop eBay for everything you need for a day on the water. We have the right gear for you, regardless of whether your allegiance lies with Orvis, Shimano or Abu Garcia.
