Fishfinder Uses

Fishfinders, also called depth finders, are an important tool for the fisherman. This device sends a sound wave into the water by way of the transducer. The sound wave reflects off an object such as a fish, or the bottom, and is detected by the transducer also. These echoes are interpreted by the fishfinder and sent to the display. This simple process can provide you with a wealth of information about the unseen region below the water's surface.

The typical fishfinder can reveal a wide range of underwater items. Single fish, schools of fish, bottom composition (soft, rocky), thermoclines (a large change in water temperature), weeds, many types of structure (stumps, wrecks, drop offs, mounds), and much more. Fishfinders with added features can also provide surface water temperature, speed, barometric pressure, and location (GPS).
