The GPS III’s can be used, however they are much more difficult. Once you get below a 10th of a mile, they do not go down into feet like most GPS’s do. Instead of saying 52.8Feet from the Cache, it will say .01 Miles. Once you get used to that, though, they are fair recievers. They don’t compare to the Newer GPS Chipsets though. You may have better luck looking for a 70 Doll etrex legend or something.
