This is the 'Top of the Range' Nautilarm V2 with GPS tracking and sophisticated Geo Fencing technology.

Geofencing allows you to set a radius around your boat within which it is 'alright' to move - we set ours at 40m.

Should your boat move outside of the 'electronic fence', you can program the Nautilarm to either actuate the alarm, or more usefully, send a text message alert and stay silent. 

This means you can alert the Police to a theft in progress, enabling them to catch the thieves in the act, rather than trying to find them after the event.
