TONE RESPONSE
Only dig up targets that induce repeatable tones. Each time you pass the search coil over a possible target, you should hear the same tone. If the tone does not repeat on each pass, varies in tone, or varies in location, then the target is usually not of value.
Inconsistent tones are evidence of high oxidation (rusted metal) or irregularly shaped trash items.
Note, however, that multiple tones may be evidence of multiple targets.
If you cannot pinpoint the location of a very strong signal, lift the coil higher off of the ground until a weaker, but more precise signal is heard.
For very weak signals, try moving the coil in short, rapid sweeps, closer to the ground.
