With all the thefts of boats off lifts here in Florida, I am thinking about putting this on the next boat. Anyone have any experiance with it? The GEOFENCE would be real nice.

I am confused, do you have to install the 6.5 foot Satellite antenna on the boat? $2000 for sea key and $500 for the antenna?

IT works...however expect alot of false alarms. If you forget to call them before a boat ride expect a phone call within 5 mins of leaving the marina!
