Coin Signals On SE PRO

I have a very perplexing signal with my Explorer SE Pro. Many times I will get a fair to good coin signal in both directions that shifts from coin to iron and back and forth. I end up digging a nail at deeper depths. I am using my 8X6 SEF coil with 22 Disc in 32 Auto sensitivity setting. Why would a two way signal not be a coin in this situation? It is a good high signal. This has happened with my stock coil also.

Put your variability at 8....and you should be able to distinguish the harsh shrill of iron from a coin. Heres what you do get a dime and quarter and run in under the coil until the sound is ingrained in your brain..Most good Explorer users usually will be stopped in their tracks by a silver dime or quarter using conductive and most hunt by sound and then check the conduct number and cursor movement as a double check...heres some cursor screens for an XS that are comparable to your unit...

Hope this helps and the next time you dig iron do remember the above for future reference...as far as cursor movement...
Do a google check on Mike Mountray metal detector as he gives a lot of info...

Thanks for your advise!!! I will use it to help solve this problem.
