Things I use
Tot lots & parks : if im in the playground part ill usually run a smaller coil, a hand digger, & a magnet aswell
When I relic hunt thats a different story cuz its usually a full day affair I get a backpack & it consista of : a opposite coil from whats on my machine ( large one, or smaller one,) bug spray,drink,snack,flashlite,extra batteries,gloves for digging, both my 18" samson lesche & the hand one, a gps, or & phone & of course the right detector & pinpointer for the job
