Alan has just about covered it with both the hand held and the vehicle mounted sets. My hand helds are the old GME's which cost me around $600-00 each about 20 years ago. Modern technology has improved them out of site and the price is about half of what I paid for one. You cannot go past the GME units,Aussie made for Aussie conditions.. When I'm working in very isolated areas on my own I carry a GME 210 EPIRB for insurance. Not much bigger than a pack of cigs. Al
