MGDS - MarineGuard's Deck Sensors are unique security devices that mount under a boat's decking. The sensor responds when an individual steps onto the deck and causes it to flex. These sensors react to even the slightest flex which is why they are the preferred sensor for steel hull megayachts. The sensitivity is adjustable and has been found to be false alarm proof since 1968,when MarineGuard developed them. CGDS - MarineGuard's Deck Sensor that is to be used with the NEW mini alarm system CG1. In our store now! |
