Trek Transponder makes sure your boat is where it should be.

If your boat moves outside a distance limit set by you (known as Geofence) you will automatically get an alarm and the boats position. You will know your boat is moving and where it is.

Trek Transponder lets you check that your boat is safely on its mooring or in its berth. If your boat is moved for maintenance you can keep track of where and when.

Trek Transponders GPS is linked to Google Earth so you can see its location on an easy to read map and read off its latitude and longitude.
