Hi all when I'm hunting schools-parks and lawns-I do rely on the meter-care has to be taken in these areas by limiting the amount of trash holes- you can't dig every little pip and peep in these areas-in open areas like old feilds and such all is fair-I mainly beep for native gold but do like to coin beep here and there-so yes I will continue to use the meter to ensure I'll be able to go back and hunt again knowing I did'nt leave it looking like a minefield-warzone-you get the point-Just my 2 centavos worth-Mike C...AZ-PS-this is a very informative site-Thanks---
