i am using this model to simply 1)mark waypoints of interesting locations and 2)use as a digital compass. (in conjunction with a map)
the recieving device is outdated and underpowered*, as far as new technology goes. Using WAAS mode the batteries last about 5 hours, while the claim is "up to 12". (sanyo eneloop, lithium rechargable - far better than alkaline disposables) So, i wouldnt use this for navigation necessarily unless using the 'tracback' feature, it doesnt have mapping capability nor does it allow the user to input a waypoint to track to, unless previously visited and marked. But for the weight, it makes a good digital compass and location tool. thanks, andrew for the deal.
this one is going to replace the 201 model that i lost somewhere near Castersen seep. So, if you go out to the Mazatzals and find a green gps, its yours!
*i dunno for sure, but garmin stopped production of this model b/c of its weak antenna and low sales (now however, the little geko is quite pricey, and usually only found overseas)
