A friend of mine heard me talking about geocaching, but he had no unit. He apparently did his research, though.
Wouldn't it be nice to have a cell phone with you while out on these treks, one that had pretty good rural coverage, in case you need an ambulance or a tow truck? And for going paperless, how about being able to use your GPSr/cell phone to get wifi in the 'burbs, so you can log that "found it!" right away?
Well, he waited for the iPhone G3 to come out and it seems to be doing the trick for him, cause he's logging 3 times as many finds as me.
I won't go that route, because I don't want to have to pay a monthly fee just to go geocaching (speaking of his phone bill; myself, I prefer the pay-as-you-go cellphone services).
I just ordered a GPS Map 76CSx, and I hope it does for me what my iQue M3 can't: keep me caching for more than an hour and a half (the iQue battery life is not good; I have a car charger but it takes about another hour and a half to recharge it). Plus the 76CSx ( and the 60 CSx, I think) have some handy geocaching utility.
