Speed Sensor For Echo Series Fishfinders - Marine Navigation & Equipment

Echo?S= series speed sensor. The speed sensor that garmin had originally recommended for use with the echo 200, 300c, 500c and 550c was a 7-pin speed sensor (010-10279-02) that required the use of a 4-pin to 7-pin adapter cable (010-11616-00). In an effort to help streamline the installation of the speed sensor for the echo series, garmin will soon be offering a new 4-pin speed sensor designed exclusively for compatible echo fishfinders. Simply mount the speed sensor on the transom of your vessel and connect it to a compatible echo series fishfinder. No adapters needed!
