Query: US Marines

This is my second Garmin product in 8 years. It will be the third deployment with a Garmin since September 11th. It has been used to report our position to higher to launch airstikes and receive supporting fire with 81mm mortars. Another plus is the digital compass which gives direction without the interference from metal. Garmin GPS products rock and are very user friendly. My only change would be to make the display for the MGRS a little bigger. I will always have a Garmin by my side and look forward to using it again this March.
