I use to have my coin tones set at 12/29 - 12/50. I would occassionally pick up a coin
at 29 but most of the time it would be a pull tab that was shiny. Old pull tabs were made
with better material than they are today. I have since raised up the tone to 12/30 on the
lower end. I do not dig all 12/30's unless I get a good round red icon regardless of depth.
Yesterday at the location of an old house where only the chimney remained I dug 2 wheats,
One 1950 and one 1953. One of them was at 7" and the other at 3". The soil here is generally
sandy and neutral. I was running manual sensitivity at 18 and the machine was at 15 to 16.
At 12/30 I do get a lot of hits but most have a lot of scatter. I do a 90degree turn and if they are still
that way I keep walking. While not being the most valuable find, I dig good signals whether pennies
or not. I also found a 1966 dime at 5" on a 12/43 hit.
I read this forum every day. I am convinced that the vid numbers of these detectors are definitely affected
by how much mineralization there is in the ground and how much moisture affects the machines ability to
reach targets at a deeper level. There are several sand plants around my home within 10 miles that
absolutely dig more than 30' deep and still have white sand when the water table runs the machines and
trucks out of the dig. That is the same exact sand you see at Myrtle Beach when they do a beach re-nourishment
of the dunes. At the same time, there are locations you can reach red clay at 4".
