A step up from the SPOT 2 you can type, send AND receive text messages via satelite with the InReach Satelite Communicator. Many functions available on this device which can be used anywhere in the world as it does not require phone signal.
A "must have" for anyone working or travelling in remote areas where mobile phone signal is not available. Small, light weight, shock and water proof. A simple press of a button sends your family & friends a text or email with your GPS location and a preset message of your choice.
The SPOT GEN3 works the same as the SPOT 2 but has twice the battery life as it can be powered either by batteries or via the included USB connection. It also starts tracking your location automatically when you start moving, and stops tracking when you stop moving.
