Hey the other week before i was to go away on a hunt my ute was broken into and everything stolen all my hunting gear. Binos, knives, gps, led lenser, first aid kits,hunting pack a bag of hunting clothes you name it all my pride gone!! Anyway i now get to go shopping for more goodies and am after another gps. I have a dog that i take out chasing pigs but don't have a tracker so was thinking of killing two birds with one stone and getting an astro 220 or 320. Can anyone give me some insight to the gps side of these i am familiar with the tracking side but not so much the gps. Are they able to load maps and waypoints and all that cool jazz? also what is the difference between the 320 and 220.
cheers alot fellas.
