I donated my old GPS (Magellan300)to our local volunteer FD for 2 reasons, when calling in a life flight helicopter lat & lon make landing easier and safer. Also the forest service can get closer to a wild fire on the ground with the dozer with lat & lon as opposed to using SRT maps. GPS is a the way to go when time counts, as opposed to trying to give verbal directions in a rural area (which the dept. covers). We cover roughly 100 sq. miles so the GPS is a good thing to have, in my opinion.
When I decide to upgrade from my 210 to something better, I'll donate it to another department. IF I could afford to do it, I'd buy a unit for each dept in the county! That's how strongly I feel about their usefulness in fire and rescue situations.
I also feel that ALL emergency personnel , fire, sheriff, ambulance, should have one in their vehicle. For the few dollars that a GPS costs, if a life is saved it's a good investment.
I'll hush now.....
