The Bilge Sentry can be added to SmartBoat Core in order to track water level inside of your keel, and the water and air temperature of your boat at all times. The cable is 1.5 meters in length, meaning any longer distances to the keel of your boat will require a Water Module Extension Cable


Designed in Norway, for Nordic maritime conditions.
