I kept the III Plus because of the maps I could use when driving or flying civilian aircraft. I am in the Texas Army National Guard in a long-range surveillance unit. The mission of this unit is to infiltrate 150 - 300 kilometers behind enemy lines to gather military intelligence and communicate it back to friendly forces.
Land navigation is one of our most crucial skills.
That far from friendly forces, there's no one to call for directions if you get lost. For the last year I have had to convert from UTM to MGRS, which is a real pain. I submitted a request some months back asking you to consider adding MGRS to the GPS III Plus. You have convinced me that I made the right choice and rest assured, I give you my highest recommendation for civilian GPS receivers. Students in my class frequently ask me which unit to buy.
