ACE 250 Coin Depth indicator

[ceoj]

I recently purchased an ACE 250 metal detector. It seems to work as advertised, but I'm wondering why the coin depth indicator shows depths of 4 to 6 inches even when a coin is on the surface of the ground. Does anyone have any insight into this issue?
Thanks.

It reads in 2inch inriments. If you are swinging your coil slightly above 2 inches it will bump it up. The distance in from the bottom of the coil.

Thanks for the input. Now if I could just figure out why it keeps telling me that old soda cans are coins I'd be a happy camper.
I know, it takes practice and I just have to keep at it until I figure it all out.

Thanks again!

You must have a target well centered (accurrately pinpointed) for depth indication to be even a little accurate and the machine assumes the object is coin sized and oriented parrallel to the ground. If there are two coins or other pieces of metal near each other, that will lead to weird depth indications. If the coin is tilted it won't be "as" accurate. Use it as a guide only. You can normally assume a coin that indicates at 6 inches will be deeper than the coin you just dug that indicated 2 inches. That said. I don't rely much on mine. You can tell more about depth by how strong the signal is when you pinpoint, how quickly it drops off when the coil is moved away from it, etc..... My two cents.

You'll eventually figure out how to tell a can from a coin as you pinpoint. If you can't, buy a machine with imaging that will tell you when an object is biiger than you wish to dig. Digging a can from time to time is not such an awful thing, BTW. Keep practicing. You'll get it quicker than you think.

This works most of the time for me. You can lift your coil up about 6-8" above the target and sweep back and forth. If you are still getting a strong dime-quarter signal then it's probably a can. If you lose the signal then dig.

Thanks for the tip. I'll give it a try!

Depth has also been a problem for me and since I haven't found any jewelery doe's it make a bell tone like a coin

I like to hunt parking areas,( like limestone gravel, river rock). I just want the small items. So I allways raise the stock coil up about 8 inchs to 10 after a good signal. I will allways look at the depth indicator and if its shows 2 to 4 inchs I will use the propointer. Like I said this is basically surface hunting. You cant run from the bell tone on large iron , cans and a host of other metals .

The rings and other jewelry I have found do indeed chime in with the bell tone.
Listen closely though because there are subtle clues within the bell-tone.
It may be slightly staticky (is that even a word??) or sometimes the signal stops a touch more abruptly than usual. Also on some targets the bell-tones may have a slight ssss sound at the end.
Lots of infomation within the belltone and a test garden will shorten your learning curve tremendously.

You will find also that if the coin is on top of the soil you will get a very distinguished beeping sound...after awhile you will learn to know that sound.
