Guardian Technology™ Continuously scans the electronic chart data in front of the boat to detect rocks, shoals, obstructions and land areas that could pose a threat if the vessel were to continue along its current course. The area searched is user-definable and is identified by a triangle on the screen. Triggering timely and clear alarms, Guardian Technology provides a new level of safety only previously available on commercial shipping systems.
