Power Source and Operating Theory

Fish finder uses an electrical impulse for the main power source. In its operation, the electrical impulse from a transmitter is automatically converted into sound waves by called as hydrophone (underwater transducer) and sent it back into the water. And then when the wave hit a fish, it will be reflected back and shape of the object displays size and composition. The real extent of what could be discerned depends on the power and frequency that was transmitted.

By knowing the speed of the wave in the water between 4800 ft/s (1463 m/s) in freshwater (typical values used by commercial fish finders), 4921 ft/s (1500 m/s) in seawater, the distance to the object to reflected the wave can be considered. In addition, the process is able to be repeated up to 40 times per second and the results in the bottom of the ocean is shown versus time.

Types and Brand of Fish Finder

Additionally, fish finder also helps the fishermen to control and find the place of the fishes underwater and it illustrates information to locate groups of the fish, underwater debris and even the bottom of the water body. To make easy in using it, it is also completed by high degree integration between the flexible GPS navigation systems, marine radar, fish finder system and also world compass.

Temperature and Pressure Sensitivity

There are many popular fish finder brands that offer a fabulous service. Some of those are temperature and pressure sensitivity.

An essential consideration when choosing a transducer is about ‘cone angle’ or how wide a beam the transducer transmitted. The wider the degree of the cone, it means the larger the view of what lies beneath. And when you move deeper, the sensitivity begins to diminish but the cone angle widens. Frequency is also considered on the transducer. Commonly it comes with 50, 83, 200 or 192 kHz. The highest frequencies between 192 up to 200 kHz works well in shallow water while the low frequency works properly in the deep water.

Portable or Fixed

Fish finder comes in two models, portable and fixed. For those who rent boats, a portable fish finder version is the better choice.

They can be applied easily where you want, the flexible wires can be saved under the floorboards or bow and out of danger way.

Power and Ease To Use

Besides that, the shallower the water around the fish, it means that the lesser power that you need. For those who prefer fishing in the deep water like a saltwater or Great Lakes, we recommend you to choose the most powerful unit can be afforded.
