I posted a similar post in another thread but considering whats just happened to Rogue Waves Scorpion (im gutted for you) I thought it deserved its own thread.
I was browsing around Expansys web site and came accross these.
Its £345 but surely if you hide this thing well enough in your boat it will greatly increase your chances of getting a stolen RIB back.
It has an internal back up battery and also will report the closest gps antenna so it will even give a rough location if no gps signal is available (ie they have it stashed in a warehouse etc...)
It could even be used when your boat hasnt been stolen by your missus to find out where you are. (ok that may not be a plus point for some people)
Im seriously thinking about fitting this to my RIB - lets face it its only the cost of a years insurance and we dont even think twice about getting our boats insured.
heres some more info
