Airmar
CS4500
NOTE: THIS PRODUCT HAS BEEN REPLACED BY UST800 SMART™ SENSOR OR DX900+ MULTILOG SMART™ ELECTROMAGNETIC SENSOR
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.
