Hello all, I just purchased a new V3i ( traded in the soverign gt) and love this new detector! My question is this: when ground balancing the owners manual say to squeeze and hold the trigger while holding the enter button,pump the search coil till background hum becomes steady. When I do this the background hum will null out completely?? Is this what they consider steady ? Still finding lots of coins (all clad so far) but just wondering if I'm ground balancing it right? Thanks!
