In parks or lawns: Screwdriver, Digging tool, brass probe, plastic probe all rolled up in a military tool wrap(made out of canvas it also serves as cloth for dirt) and a nail pouch for good and trash, headphones, and merlin pinpointer.
Woods: Small craftsman shovel, bug spray, bottle of water, nail pouch, headphone, pinpointer, and extra batteries. Also have a weedcutter in the van if needed. Since I live in Iowa never had a need for a gun...farmers take care of anything big enough to kill livestock.
