Metal detector acting erratic

[TREASUREHUNTERDAN]

Hi,
I have a Garrett ace 250 and this morning I turned it on outside away from any electrical stuff and it was acting crazy. Readings and beeping constantly. I turned the sensitivity down to only the second notch and it worked good. It has never done this before. I can usually turn the sensitivity up to the 2nd highest notch or the highest notch without a problem. Has anybody else experienced this and does anybody know how to correct this problem?
Thank you,
Dan

Mine only does that when there is another metal detector too close. might try changing the batteries...just to be sure.

..............TREASURE HUNTER DAN...........THE ACE 250 HAS A RESET BUTTON ..................TURN IT OFF AND TURN IT BACK ON AND HOLD IT FOR AT LEAST 5 TO 10 SECONDS..................This will reset the detector to the original factory settings!!.....................................MERRY CHRISTMAS.............JOE

Ditto what Myelo said, my 250 does the same when batts are low. Check your coil connection. Try reset if needed

Check the oil level, battery fluid, and wiper fluid.sorry couldent resist

I just smack it around a little bit and show it who's boss.

(Actually, it's probably the batteries. Mine did something similar earlier this week. Changed the batteries and everything is fine.)
