So this is the kit we use when we go geocaching. I throw it all in one of those crappy bright orange cinch sacks. The only thing I’m missing is an actual compass, but I feel pretty good having an extra set of batteries for the GPS. We chuck those bottle caps in caches we find for fun. The stamp pad is for stamping the log book when we find stamps in caches. I used to do a lot of letterboxing before I started geocaching, so finding a stamp in a cache is a big deal for me.
