Observation on depth indication

[Captain Kirk]

I have found that the depth indicator has considerable error depending upon the amount of air between the ground and the coil.

I generally perform the pinpointing function with the coil about 1" above the ground (at the grass top level). I consistently got depth readings of 6" to 8". I would dig a deep plug and find the coin near the top of the plug. Through experimentation, I find that what was a 6" to 8" reading would drop to about 2" when I pressed the coil firmly against the ground. Are the rest of you finding similar results?

to all conductors or do you see it mostly on high coins?

Thanks

Tom,

I can not give an informed opinion about whether it is on all conductors. I mostly only check the depth reading if I plan to dig. I have been hunting using 3 tones and it is true for nickels as well as copper pennies, dimes and quarters. I will have to do some testing to determine the behavior on non-coin items. The depth indications seems to be reasonably accurate on coins if you press the coil firmly to the ground.
