Bury it right!
Burying your waste at a proper depth (at least 150 mm) is far better than using a shallow hole or covering it with a rock. Properly buried waste and toilet paper decomposes naturally without impacting other campers.
The Deuce makes it easy to dig a small 'cathole' to the right depth. It is the only trowel that can be used upside down – you can dig with either the wide end or narrow (handle) end.
Designed in Colorado by Mike at The Tent Lab and made by DAC in South Korea, The Deuce #2 is ridiculously light at only 17 grams and measures 173 mm long. It's very tough and sharp enough to cut small roots.
