I have branched out from tot lots to hunting several park lawns as well. My Vaq has led me to some coins, bottle caps,foil, and lots of junk. Tell me am I crazy but tree roots can trick me into thinking they are good targets! Some times half of my good hits turn out to be tree roots. The disc setting can be at three o' clock or more sometimes. Sometimes only a small part of a root reads hot. Why ??
