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.
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.
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.
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.

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. Keep reading for tips on finding the right system for your boat.
Here’s a useful tip for judging the width / thickness of a sonar return: switch on the vertical flasher (also know as a-scope) on your fish finder if it has one (to do this on the Deeper App, go to Settings > Sonar > Vertical Flasher). The vertical flasher on the right side of your screen will show you exactly what’s under your sonar at this exact moment. You can use it for vertical jigging, and of course forice fishingtoo. For judging fish size, look at both the thickness and width of the returns on your vertical flasher. A larger fish will give both a wider and a thicker return.

Whether you're off to a nearby stream for some fly fishing or heading out into the open waters for a deep sea fishing adventure, the right fishing gear will make your trip even more exciting. When the weather's nice, find a quiet spot to cast your line with a new fishing reel. Pick up a rod and reel combo that's ready to go right out of the box or customize your fishing gear with a separate rod and reel.
The swivel sinker is similar to the plain one, except that instead of loops, there are swivels on each end to attach the line. This is a decided improvement, as it prevents the line from twisting and tangling. In trolling, swivel sinkers are indispensable. The slide sinker, for bottom fishing, is a leaden tube which allows the line to slip through it, when the fish bites. This is an excellent arrangement, as the angler can feel the smallest bite, whereas in the other case the fish must first move the sinker before the angler feels him.

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.

As you look for a GPS/fishfinder combo, keep in mind that the best power and frequency won’t mean much if you can’t use the information. Think in terms of a computer. You can have the most-powerful and efficient computing capability, but without a high-quality monitor, the data does you little good. That’s why it’s always a good idea to spend a bit more to get a top-shelf screen.

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.
Pay a bit more and you get a bit more with the Humminbird Helix 7 SI GPS. The screen is massive, compared to other combination units – 12 inches with 1280×800 pixel resolution. The any-angle viewing and reduced glare are excellent. The Humminbird also has the electronic capability to support almost any advanced feature you can imagine, including, of course, precision GPS.
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.

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.
The sound wave spreads as it gets further from the transducer. The wider the cone, the larger the coverage area, but the as the cone angle spreads, sensitivity diminishes. A 20-degree cone is considered a versatile angle for fishers who frequent different water depths. More advanced devices come with double and triple beams, ideal for scanning deep water depths.

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.

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.

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.
