I dug my deepest Lincoln.

[lse450cc]

It was at 11 1/2 inches .Settings used with the stock coil. ,Open screen, 2 Fe tone, Fe set at line 25 . Sensitivity was at 23 in the manual mode. I was using auto ground balance.
The gain was set at 30.

That is one deep Lincoln. Makes ya wonder how deep the old stuff is.

Dug a few deep memorials myself yesterday at 7 to 10 inches, and were hitting 12-45,46...Some wheats were hitting numbers that high also.we got alot of rain and everything seems to have been reading a bit higher than normal, i have scored 60 or so silvers this year at an average of the same depth in that spot... sometimes you got wonder how modern coins got that deep so fast?most of the silver was from the 40s

Just wondering if you guys are noticing that the deeper coins are in areas that get very little shade? My theory is that the more sunlight the area gets the deeper the coins get.

I'm thinking that as the ground dries out from top to bottom the dryer ground on top actually has a pushing action on the coin pushing the coin deeper into the softer ground below it. Then when it rains the ground expands and the coin tends to lag behind the dirt expanshion. Then the ground dries again starting the process over again. But in the shaded areas the moisture stays a little more consistent between rains hence it is not pushed as much as coins in sunny areas.

I'm not sure of this yet but have been noticing it lately. So wondering if anyone else has any thoughts on this subject.

Man an 11" memorial penny thow, that is really deep especially for the stock coil! I don't think my big 17" coil can even air test an 11" penny. That says allot for the in ground hallow effect.

I am almost certain that the 17 will pick that up in an air test.

Most likely in an open area an eleven inch deep memorial is not at that depth naturally but due to human or animal disturbance of the ground. Otherwise it could be at the bottom of a washout, an area where leaves get stuck and return to the earth, under a blow down after it rots away, etc.

The Lincoln penny was a wheatback. Several coins were in the nine and ten inch range. This coin was found in a old baseball field where a new road was built through the middle. Dirt was pushed around and the field was releveled. That is why it was so deep.

I have a program I use that's 2 tone and it will go super deep. The flip side is its not for the beginner, I only use it at my old sites where I'm digging everything. I know for a fact in 2tone it will pic it up at that distance in a air test with ease.
