As a relatively new cacher, I've found my Trekking pole (as I learned from GeoTrekker26) a valuable tool for poking around, moving leaves, etc. It's also nice for going up and down slopes! Also I would reiterate, please carry a few sizes of replacement logs and plastic bags. You will encounter many full, or wet logs that you can remedy with these supplies. Of all the tools I carry, I've used my tweezers and mirror the most.
