So I just bought an Ace 250 as my backup detector and for exploring my local beaches.

I also buy the 8.5 x 11" DD coil that is advertised as being compatable with the 250.

I figure the DD coil will handle the mineralized soil better.

I hook it up, turn on the detector and it immediately starts going nuts, beeping randomly.

Thinking it might be in house EMI, I go outside but it does the same thing until I turn the sensitivity down to 4 bars. Then it quiets down.

So is this normal or have I bought another defective detector/coil?

Really anxious to hear from Ace 250 users out there.

Just as a follow up, I attached the stock 6x9 coil and when I had the detector set at maximum snesitivty, I got a very rare false signal. But it was mostly quiet.

I was holding the detector in the open air, not on the ground.

Sounds like a coil problem to me. You might want to contact the company you bought from and get to the bottom of it.

I reconnected the coil and made it less tight. That seems to have fixed the problem.

Smudge,If you plan on using in wet sand run in coin mode and notch out everything left of the nickel, and run at four bars sense,You should get no false signals.HH Wayne in Delaware

Rap your coil wire tight around the shaft sometimes when the wire is lose it will act up

Sounds normal if it's in the air..

Sounds like the connector. Give it plenty of room if you tighten the coil wire around the shaft. Mine sounded off because I had the wire so tightly wound around the shaft that it pulled on the connector. Sometimes mine won't come on and I can wiggle the connector and everything's fine. Also, the battery wire springs sometimes don't settle right on the batteries and have to be adjusted or just roll the batteries with your fingers while they're in the holder. Not an always problem, but I noticed it a lot whenever I was changing back and forth from sniper to regular coil.

I would reset the detector by holding down the power button until it double beeps around about 5 to 8 seconds it resets to factory settings, I do this every time I change the coil. Hank
