Sure, any machine will do but..... case in point..... The Gold Bug 2. It will certainly "pop" on silver coins. But rusty nails, white metal, tin foil, and others will get thrown into the mix. I don't particularly favor displays but when "cherry picking" specific metals, the machines with displays have their purpose. I have three display machines. I am favoring the Cortez right now. I would not think of looking for coins with my GB2 unless prepared to spend a lot of time digging trash with the coins. ╦╦ÇBeing one of the most conductive metals on earth, I’d think that just about any machine would pop on Ag!
Somebody please enlighten me if otherwise.
Ag makes my Equinox really sing!
