About the Business
A Trek Transponder Security System consists of the Trek Transponder unit installed in an inconspicuous location on your yacht or cruiser connected to the battery/batteries, security sensors, shore power or solar if you have those, and other sensors of your choice on board. You can use wired sensors or wireless.
Trek Transponder has a SIM card in it so your boat has its own phone number and can send SMS to you by itself if there is a problem on board, or reply to your SMS when you check whats happening.
