If you have been fishing for a while, you may be familiar with the purpose of a fish finder.For those of you who are new to the game, a fish finder is exactly as the name indicates. It’s a device that is used to locate fish in various bodies of water by making use of sonar. It will display the information in the form of a graph. The user reads the graph to locate fish, underwater objects, and the depth of the body of water.?How it works is similar to the principle that is used in submarines. Sound waves emitted by the device, bounce off of the underwater objects and are reflected in the device. The reading received by the reader indicates the shape, size, and composition of the object. Most fish finders will create a basic image on the screen that shows the bottom of the water body and the positions of any fish in the area.?Table of Contents:220.127.116.11.18.104.22.168.9.10.Before you purchase a fish finder, have a look at some of the most important features that you should keep an eye out for.?A transducer converts energy from one type to another. It is the most important part of the fish finder and determines the that your finder will display. The better the quality of the transducer, the more accurate the location of the fish.
An electrical impulse is converted by the transducer into sound waves, which are then transmitted into the water. The sonar waves bounce off the surfaces, fish, and debris and return to the device.?FrequencyYou also have to consider the various frequencies. Higher frequencies will give an image much more clarity. Higher frequencies work perfectly at shallow depths to detect smaller fish. With lower frequencies, the image on your device isn’t as detailed. However, they have a higher capacity for energy and work better in deeper waters. You need to find a fish finder that falls somewhere in the middle to be used in various bodies.?PowerThe power of the frequency of the fish finder also has to be considered. The more powerful the fish finder, the clearer the image you receive. With higher wattage, the sonar waves travel faster and deeper. Higher power is crucial in deeper waters.?Cone AngleThe cone of the fish finder refers to the area that the sound waves cover. The larger the area of the cone, the wider the area it scans. Larger cones don’t necessarily provide better results and could be weaker. Smaller cones can provide clearer imagesThe depth of the cone is important and can go as deep as 150 feet below the boat. The angle of the cone is important too, and you should find one with a 20-degree angle.?The display screen of your fish finder is an important part of the fish finder. The image below the water surface will be displayed on it. You should be able to easily navigate, and also be simple. Too many features will just clutter up the screen, but you still need enough features to help you locate the fish with accuracy.?Greyscale or ColorYou can buy a finder that displays the image in black and white or color. For color displays, the stronger the echoes, the darker the color of the image. Colored screens will indicate the types of fish and the depth of the water. Grayscale images are sharper when the resolution is higher.?Screen ResolutionAs is with most screens, the higher the resolution, the clearer the image on your screen. Higher contrasts are optimal to be able to enhance pixel performance. You should always opt for higher resolutions when you purchase the fish finder.?Screen SizeFishfinders are available in different sizes and the screens can vary as well. Larger screens can hold more information. You can also opt for split-screen features.?Fish finders shouldn’t be fragile. Your device will be exposed to the elements and take up way too much space. Larger finders are useless on small boats. Smaller fish finders will be less intrusive but have smaller screens, which can make it harder to see the details. Your decision will depend on the size of the boat.
A GPS fish finder can be very important if you find yourself fishing in the middle of a fog, or if you drift too far out. The GPS can safely direct you back to safety and go back to land with the aid of this feature. You can also plot waypoints so that you can remember good fishing points for later.?Notice: The Wading List is reader-supported.
