Depth readings on coins

[burried gold]

to all those people that have dug silver dollars and half dollars with the mxt. I know the depth reading is based on coin sized objects and has always been very close on silver dimes and actual depth will usually be a little deeper on quarter from what the mxt tells me. what about the 50 cent and large dollar coins? is it likely to be much deeper that what the machine says? I have had several targets that have pinpointed at the 7-8 inch range. I start by plugging a hole to about 6 inches and using a probe to the 8-9 inch area and not finding anything so I give up thinking it is deep iron that fooled me. could these targets be a silver half or dollar at a greater depth than what the machine is telling me? Possibly in the 9-12" range?

To answer your question, more than likely no it's not a large silver coin. It's usually a large metal object such as a bucket, piece of large lead, shovel or possibly that old Studebaker. HH, Nancy

[size=large]experience is the best teacher. you probly know or have heard that your ground may bring differant readings than someone elses.
only way for you to know how close your machine matches what you'll find is dig. then you'll know that in your world your readings are thus and so. jmho.
this apply's to any machine but especially the deep seekers.

do large coins read that far off on the depth reading? I do not have any to bench test with. will they be 3"-4" deeper than the depth reading?

[size=large]all the posts that i've read were concerns with minelabs and fishers machines having problems with the readings being off. i can't recall any with the mxt. ya got nancy's reply. she would know if anyone would. all she said was you just found yourself a studebaker. now that would be a great treasure. i use to own one. you will need a bigger shovel. and don't forget to fill the hole back in.

I've found deep coins and they read fairly close to what they would any other time. I've never found that elusive silver dollar yet, but someday. If you've got a thin dime vs. a extra fine dime, you'll get a different reading such as possibly 76-77 vs. 80-81 depending on how wore the coin is. This goes for all other silver coins as well. Hope this helps........HH, Nancy

Any detector's coin depth read-out is going to be somewhat close, but seldom spot-on accurate. A lot will depend upon the search coil used and even the operator's skill in engaging the PP function and coil presentation.

As others stated below, however, the larger silver coins might read 'off' a little but seldom more than an inch or so. There will be times, too, when you get a good audio response, a desired target ID, but the object isn't really what you hope for and is smaller and located rather shallow. Sometimes, these small good-conductor targets suggest a coin at 7"-8", but in reality they are just a piece of junk in the upper 2" or so. If you haven't, always make sure you check the removed dirt.

The MXT is usually very close to correct on coin depth, but it's not a function I rely on a lot.

thanks everyone. i was just making sure i was not missing stuff. the concept of small targets being shallower than the display shows is what made me wonder if the opposite was also true for large coins. if i was hunting open fields i would have just dug the targets out but in a park setting it is not practicle to think i could dig a rusty nail or iron at 12 to 24 inches

Couldn't you quickly solve the question of big iron by flipping into the prospecting mode and checking iron probability?

That is what I usually do to help eliminate iron on deep targets. Around here, though, aluminum is the problem...not iron.

I never thought of that. I will try it.
