...a waterproof phone case? With your hobbies?
Just an alcohol proof one.
I have an otter box to prevent smashing it's but not fully waterproof. I usually either leave the phone behind or put it in a ziplock, but I didn't have any :-(
I wanted to take it for timing and also I had no map in a new area, so in case I got turned around or injured. Found a cool little lake (Ties?) with a couple of nice campsites on it. Also managed to find a park boundary.. I think it was Petroglyphs
I have a Lifeproof Nuud, which is waterproof but not smashproof if I drop the phone on its screen, which is uncovered. The nice thing is that I can leave it on all the time.
