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.
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.
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.

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.
Detection range (depth) of a fish finder depends upon the frequency used for ultrasound transmission. In principle, the higher the frequency of ultrasound, the shorter the propagation range can be. The wavelength of high frequency ultrasound is short, and its directivity angle is narrow, which enables detailed searches, but it attenuates significantly while travelling through water. Low frequency ultrasound is characterised by its long wavelength, wider directivity angle and high level of tolerance toward underwater attenuation, hence enabling wide-area-searches in deeper water. To summarize, you can choose low frequency if you are searching in deep water and high frequency if you are conducting a detailed search in shallow water. Further, when using low frequency ultrasound, you may be able to conduct more precise deep-water searches by adding an optional Power Adapter, which amplifies the transmitter power to a few kilowatts. Please note, however, that when using the Power Adapter, a dedicated transducer capable of handling higher transmitter power will be needed.

Points are more gradual than drop offs, but spotting them is just as easy (see the screen shot below). Make sure you maintain a steady speed when trolling or reeling so you get an accurate reading on how steep the incline is. You should scan with a narrow sonar beam to get the clearest reading, and to ensure you see any shelfs or humps which wider beam scanning might not pick up (our page onhow sonars workexplains why this is).
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.

Unless you know where fish are lurking, casting out anywhere on the water doesn’t necessarily guarantee a bite. Finding where the hot spots are will help you save time and money while fishing. That’s where fishfinders come in. An essential part of any modern angler’s arsenal, a fishfinder makes catching more fish easier.  Fishfinders help you pinpoint the honey hole using SONAR so you can see where the fish are and at what depth they are hiding. No more wasting time, tackle or line on deserted spots in the water. From standalone units, fishfinder/GPS combos, networked or multi-function displays, West Marine offers a wide array of fishfinders from the top brands on the market today.

Hand nets are held open by a hoop, and maybe on the end of a long stiff handle. They have been known since antiquity and may be used for sweeping up fish near the water surface like muskellunge and northern pike. When such a net is used by an angler to help land a fish it is known as a landing net.[12] In the UK, hand-netting is the only legal way of catching glass eels[13] and has been practised for thousands of years on the River Parrett and River Severn.
The CHIRP sonar that is built into this model is second to none in terms of performance, and always gives you a clear picture and measurement of the floor and surface beneath your boat, as well as the location of the fish around it. Another feature that we really enjoy about this Humingbird fish finder is that it comes with a built in SD card slot so that you can save your favorite waypoints to it. You can even upload additional maps to your software using the SD card feature.
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.

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.

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.
Harpoons are spears which have a barb at the end. Their use was widespread in palaeolithic times.[11] Cosquer cave in Southern France contains cave art over 16,000 years old, including drawings of seals which appear to have been harpooned. Tridents are spears which have three prongs at the business end. They are also called leisters or gigs. They feature widely in early mythology and history.
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.
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 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 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.


Hockey tape was made for the ice, and even though hard-water anglers are looking for a different kind of score, they should always have a roll on hand. A few wraps around the butt and foregrip of any jigging rod immediately improves the hold and comfort, but hockey tape can be used on any ice tool. If you’ve ever had the cheap rubber handle cover disappear from your ice scooper, you know the feeling of metal freezing to a glove or the burning sting of touching it with your bare hand. A few wraps of hockey tape can easily fix that. Should your bibs or jacket get hooked or ripped, the hockey tape will keep a tear from getting worse until you can make a permanent repair.

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.
