OK so I've just started taking the family (including the four legged fleabag!) on these Geocaching excursions. Mainly as we need to burn off extra calories before pigging out on a Sunday roast and sleeping on the sofa (....Ohhhhhhh HEAVEN!)
Anyway, I've been using my iPhone but the gps chomps through the battery like no ones business to the extent that I only get through about 3 closely located caches before the battery goes from 100% to 10%.
I'm looking for some advice on which are the more accurate and reliable devices from people who can also spot a good deal as well as a well hidden cache.
