This is the 2.4Ghz 4-Channel Receiver for the Rage Eclipse and Eclipse 650 Sailboats.
SPECIAL NOTE: This is the new auto-bind model, which is NOT compatible with the original manual-bind transmitter/receiver set up. The original manual bind radio systems were installed on units manufactured before 2021 that have a manual-bind transmitter. If you have a newer model that has auto-bind, you would need this B1330B model.
