Whether you are a commercial fisherman or just love the sport, an electronic fish finder can be an invaluable tool. It can literally take all of the guesswork out of choosing the best fishing spot. While there's nothing wrong with fishing the traditional way, a fish finder can keep you reeling them in all day long. They are very affordable and are compact enough to be used on the smallest of boats.
We carry all the lines of marine electronics: Garmin, Raymarine, Interphase, Humminbird fish finder, often misunderstood as humming bird, Lowrance fish finder and others. Buy yourself a fishfinder, the perfect boating accessory, to increase your haul of fish. Grab your rod and reel fishing pole, attach your favorite lure, get busy tugging some lip.
The concept of many electronic fish finders is simple; however, how they actually work is far from straightforward. Almost all fish finders work using sound waves. A small electrical impulse is released and converted to a sound wave, which transmits through the water. Initially, the sound wave is narrow, but as it penetrates the water, it spreads into a beam. The frequency is inaudible to both humans and the fish. When this sound wave hits an object, it transmits back to the original source, and then shows its results on a screen. The device calculates the distance to the object by using the amount of time between the sound wave leaving the unit and returning. Depending on how good the fish finder is, it will then display the size, shape and even give you an idea as to where the fish is located. The display will often show you the bottom of the bed, alongside all plants and sediments. Each fish finder has its own symbol for what it believes may be a fish, and it displays this information on the screen.
Although fish finders come in various styles and offer different options, there are basically two different types, single frequency and dual frequency. Single frequency devices are much better suited for lake fishing, or fishing in shallow coastal areas. Dual frequency fish finders also referred to as dual beam are more suitable for deep sea fishing. The transducers on these models limit the size of the beam of sound lowering the frequency.
The display screens can range from a compact four inch size all the way to seven inches or more and are available in various display resolutions. Higher resolution screens produce clearer images and larger screens will give you a wider view of the landscape beneath your boat. Color screens are also a better choice if you do a lot of fishing in full sun because you will be able to see the display better.
Power is another thing that you need to think about before purchasing a fish finder. Generally, the more power the device has the better the display images will be. Power also determines the depth at which the fish finder works and the quality of the sound frequencies. The depth specifications listed on our website are based on using the device in clear water. Murky water or saltwater will limit how deep the sonar can penetrate into the water.
