A buddy just purchased a new se pro. I am using an EX ll with the pro coil. We spent about 3 hrs together with these machines. I was finding targets clad dimes and pennies for the most part, they where checking my targets with the se, it seemed unable to lock on and stabilize on, even 2 or 3 inch finds. We tried it in quick start, smart and digital, with the sensitivity from 10 to 25, tried discriminating out all but coins and jewlery, same results in all modes. ground balance,(noise cancel), had no effect. re-set the machine to factory settings several times, no help. In smart mode the cursor is all over the screen on targets the ex had located locked on and identified, same situation in digital, could not make up its mind what value to put on anything. Dissapointing situation..Tried the spot after the target was dug both machines silent, so it was not trying to settle on more than one on top of each other..I guess my question is has anyone had this problem, and have we missed some little detail that would cure this. any input appreciated.. Thanks, don
