False signals - am I doing something wrong?

#1
Hi All,

I just took my new Discovery 2200 out into the backyard for the first time, and I got nothing but false signals everywhere I swung it. I tried swinging it fast and slow, almost touching the ground to 3" or 4" above the ground. It has four different tones for different metals, and I was hearing all of them. A couple of times it acted like it found something, but I dug and there was nothing there. But most times it just beeped randomly, in no pattern that I could see. Am I doing something wrong? Could the detector be defective? The ground is wet from rain, could that be causing it? Does the ground have to be dry? Any advice would be greatly appreciated.

I have a different machine than you do but what usually causes false signals on mine is when I have the sensitivity set too high. Don't know if you have a sensitivity setting on yours, but if you do, you might want to try turning it way down then working your way back up.

If there's no sensitivity setting, then I haven't got a clue. :icon_conf

Oh yeah, I forgot to mention that. It does have a sensitivity setting, and I turned it all the way down, but it didn't seem to help. Still got the false signals.

Then the only other thing that I would double check would be the ground balancing. Other than that, if you haven't already tried, move it to a different part of the yard. If you've already tried that, make sure that the coil wire is snuggly screwed into the control unit.

Yep! That what I would Try!

1) Adjust the Sensitivity to a low setting in the event
of false signals.​
Always begin use at a reduced
sensitivity level; increase to full sensitivity after you have

become familiar with the detector.

Well, there is no ground balance control, so I assume it's automatic. The powerlines are in the front of the house, about 100 feet away. Too close? And I have no coil cover.

More testing

I tried a bench test inside, and it seemed to work properly. It was pretty accurate with a nail, penny, dime and quarter. It gave the proper tones, and indications on the display (although I did get the occasional pull tab indication).

I took it outside again, turned the sensitivity all the way down, and still got a lot of false signals. I tried discrimination mode, but still got false signals. I'm starting to think the thing is defective.

I know hundreds of people use Bounty Hunter detectors and get great results. But I can't help but wonder if I shouldn't have gone with a different brand...

Take it back outside about 30 or 40 feet away from where you're having all the trouble. There maybe something with ground right there, especially if it's working in the house.

I've actually tried it all over the backyard (and it's a big yard) with the same results.

Looks like just about everything's been covered, the only think I can think of is to take it to a entirely different area, local park, school, anywhere but your immediate area. You're not wearing steel toed shoes or shoes with metal eyelets are you?

No, no metal in my shoes. Yeah, I'll try it at a park to see if it does it there. It's a little frustrating and a letdown, I can tell you that.

Welcome to the site! Nice to have you on!




I agree get to the nearest park, or elsewhere and try it out. Good luck to you, Beale.

something I noticed that others didnt mention, if your connector is a plug-in type...check for corrosion in there sometimes that can cause bad signals in high mineral soil. To clean that use a standard pencil eraser, just rub the connector clean and rinse with rubbing alcohol.

I know I'm late on this, and hope everything is doing well for you now, but
if you haven't already tried, change your batteries out, and see if there is a change. Does your machine have a battery indicator on it ?? I run the BH Land Star, so they are close. !
