Product Specifications

The PiranhaMax is the easiest to use fishfinder ever. For most anglers, all you'll ever need to do is power on and fish! The PiranhaMax automatically determines depth and makes adjustments to keep the bottom and fish visible on the display. The PiranhaMax uses sonar technology to send sound waves from the transducer into the water. The returned "echoes" are plotted on the display, creating a very accurate picture of the underwater world, including distance to underwater objects such as the bottom, fish and structure.
