Airmar’s revolutionary CS4500 makes cutting-edge speed sensing affordable. Instead of a paddlewheel it uses two transducers mounted in one compact housing to detect particles in the water and calculates speed based on their distance apart. The CS4500 reacts instantaneously to changes in boat speed and is one of the most reliable and accurate speed sensors on the market.
