FishFinders from Garmin

NavHome offers Fishfinders and Sonars from Garmin International. These units combine innovative technology and ease-of-use operation to help you get the most out of your time on the water.

The word "sonar" is an abbreviation for "Sound, Navigation, and Ranging".

A Sonar consists of a transmitter, transducer, receiver, and display.

In the simplest terms, an electrical impulse from a transmitter is converted into a sound wave by the transducer and sent into the water. When this wave strikes an object, it rebounds. This echo strikes the transducer, which converts it back into an electric signal, which is amplified by the receiver and sent to the display. Since the speed of sound in water is constant (approximately 4800 feet per second), the time lapse between the transmitted signal and the received echo can be measured and the distance to the object determined.

NavHome Stocks the following Fishfinders

The unique and exclusive See-Thru technology in Garmin’s Fishfinder series allows them to hear both weak and strong signals simultaneously, giving it tremendous dynamic range. The result is a display that is capable of showing strong fish returns even when fish are suspended inside structure and thermoclines.

Second, Depth Controlled Gain (DCGTM) automatically adjusts Fish Finder sensitivity according to depth, not echo intensity like other Fish Finders. The result is a much more detailed and accurate picture of bottom structure.

In all the Fishfinders from Garmin, water temperature is displayed below the depth reading for quick visual reference, and a unique control bar identifies the most commonly used fishing settings.
