I find it work best for cache along highway or road . there be lot of grab and go cache that be fun . one reviewer say he do not like the small cache . I feel the same , but I have come to appreciate they . sometimes they be very easy and then there be other that I have not find after several trip back to the area . yes , it do have limitation . and it be a little pricey consider the lack of map . once I be within a few foot it seem ; I be stop by a steep bank and the Interstate beyond . but when I turn it on and can locate treasure that be on my way , I be happy . and I bet it do not cost as much as that coat , or kitchen gadget , or knick knack you do not use any more . I have not use it with kid much , but it be a great introduction to geocach for my friend . usually I give they my `` real '' gpsr and use this to confirm we direction . lot of they now geocache with I . a little study will help you enjoy this great hobby . go to -lrb- ... -rrb- -lrb- the official site for hide and seek -rrb- , create a free account and browse around . learn the lingo , check out the map around you house . bet there be several cache to find .
