What's the deepest coin you guys have dug in turf hunting with the Etrac?---No fish stories now!! ----The wife & I both run Etracs & she got a Morgan dollar at an honest 12".----I dug a dime at 10".----Both these coins were retrieved in moist (moderately mineralized) ground.----------Del

The maximum depth you can get on a single coin is 10 - 12 inches. That is a mathematical certainty. The coil cannot penetrate beyond 12 inches maximum on a coin sized object in soil. This applies to other machines using same size coil. To get deeper than 12 inches the ground needs to conduct the signal like on salt wet beach's.

Soil content has a lot to do with it. Thick dense clay you will see less depth, but it's not a problem since speific gravity doesn't allow coins to drop deeper than 8 inches or so. I have 1700's finds that were 4-5 inches here in NJ where soil was undisturbed. I've never dug anything that was too deep. Bad news though since a lot of the old timers with less capable machines were able to get most of the goodies years ago.

The deepest I have recovered a coin so far was in the 8-10 inch range. Can't be exact becase it came from a scoop of dirt. I have dug metallic trash, smaller than a coin at an honest 12 inches though, so I am confident it will pull coins from that deep too. Just have to pass over one actually that deep. MOST coins won't get that deep under natural circumstances.

I think the more important question is how deep can your detector beep a coin that has a chunk of iron above it.

I recovered an 1835 Draped Bust half dime at 9". It was next to an iron strap hinge. Got the high silver warble only north/south, not east/west.

most of the coins I have found are between 3 and 7 inches. Of course I'm not counting pennies.

A memorial at 10 inches measured. Aaaaaahh! I also dug a 1916 Barber dime at 10" as well.... not the same place.

I dug a barber dime 11-12 inches. To be fair, it didn't hit like a coin at all. Bounce all over the place in and out of discrimination, but pinpointed. At the location there were very few targets with vitually no trash......and I was bored. But at another location I would have walked on the hit. And at this location I could run +3 auto since the soil was kind to the machine.......most places I hunt I run at auto or +1.

In most other locations 8-9 inches is the range where you can lock on coins solid with good ID. After that in mineralized ground it get tough....
