Impressed with Depth on Anfibio

[The Digger]

I was able to get out for a little while today to swing my Anfibio. This was the first time I was able to go to an area I had pounded hard with my Explorer.
I found two oldies, a 1909 Wheat Cent, and a 1942 Mercury Dime that looks like it was lost in 1942, as it is in excellent condition.
Both of these coins were easily 9-10" deep, and I am sure I have swung my Explorer over both of these coins multiple times. The signal it gave on these was very strong.
I am impressed and anxious to spend a day detecting my previous pounded sites.

I’ve finds..how was the visual ID on the coins at that depth?

The visual target ID was good, but did not lock on to one number. It bounced around in a range that I'm looking for.
The sound and depth meter are what's really important to me. I was running in 4 tone with gain at 75, disc at 20, and in14 khz.
