I have a bounty hunter platinum i just bought. I can mot get the ground grab to work. As the manual says I hold it up, hit the pinpoint, lower it towards the ground and i get the low tone and raise coil message.Ive checked the ground for metal with my Tesoro its clean. Also beeps a high tone dig it out and cant find it.
I have a Garret carrot so I'm tempted to send the Platinum back.

Hello,

First off, you have to be in All metal mode. :cheers:

While in ALL METAL
Mode
, press and hold
the Pinpoint button to
actuate GROUND GRAB.
Computerized Ground
Balancing.

The Process is as follows:
1. Find a patch of ground which is free of metal.
Use the DISCRIMINATION Mode, with no targets discriminated out.
2. Enter the ALL METAL Mode of operation.
3. Hold the detector with the searchcoil a foot or two above the ground.
4. Press-and-Hold the pinpoint button.
The GROUND GRAB Computerized Ground Balancing line is
illuminated.

5. Lower the searchcoil down to within 2 inches of the ground.
6. After successfully ground balancing, release .
You have successfully ground balanced after a 2-digit number appears in
the middle of the screen. After 3 seconds with the same 2-digit number
displayed, you will hear a repeating high tone, indicating that ground
balancing was successful.
If the detector is not able to ground balance, “ _ _ ” appears, a low-pitch
warning sound alarms, and the message “Raise Coil” is illuminated. You
could be over a piece of metal. If so, find another patch of ground. The
detector will also not Ground Grab Computerized Ground Balancing on
a wet salt-water beach.

Hope this helps.

I have followed tge directions and managed to get it to work once but then the pinpoint mode doesnt work. Im thinking something is wrong with the machine.

Unfortunately, you might have to send it back for repairs. How old is your machine?

If you bought it from a regular dealer call them first. If you bought it from a mass merchandiser you can probably return it.

In any case you can call bounty Hunter and have a chat with their customer service people about it.

If you want to discuss it further off-line feel free to send me a PM.

The symptoms described sound like most likely the internal phase calibration is off. I'd recommend getting it recalibrated on warranty, or swap for another unit if the dealer is willing.

I called bounty hunter and their tech said it sounded like the coil was bad,and send it to them. Its on its way to El Paso lol. I've dealt with First Texas before, never had a bad experience. Thanks everybody. Just in case I'll keep you informed. HH

Good luck. I'm sure First Texas will get it going properly.

Well sent it back. First Texas replaced PCB? Got iy back its doing the same thing. Called first Texas said it couldnt be the machine i must be doing something wrong. I was on the phone with the tech from Hurst Texas and he told me to pump the coil ground balancing I said that's not what the directions say say hold it a foot or two about the ground pinpoint in the all metal push it towards the ground. He said hold it two inches above the ground push to pinpoint and let it ground balance. He kept saying i must be over metal when the coil would overload. Machine would not quit beeping just erratically. Im gonna put it in the closet and buy Tesoro from here on out.

Also there are some powerlines near but theyve never given me trouble before. I have had an F4 a T2 classic ans Delta 4000 emi hasnt been an uncontrollable issue.

In looking through the thread, I suspect that the machine is fine and that there's something you're doing that's causing it not to grab. The instructions may be ambiguous, words don't always explain well a physical maneuver. Besides which the information you received over the phone is probably correct for most of our related models but the Platinum may be a little different. I don't remember myself exactly how the Platinum does ground grab, so I'm forwarding a link to this thread to a couple other engineers who are more familiar with the Platinum software and hopefully we'll get a straight answer out of this and be able to resolve the problem.

Thanks Dave. I have managed to get it to ground grab once this morning doing it the way the tech told me on the phone but then the pinpointing works erratically. It will indicate something is there then there will be nothing the next second. Also i will sit the detector on tge ground to dig and it wont quit beeping.

Haven't gotten the response from the other engineers on the ground grab thing yet. The pinpoint issue may be connected to the ground grab issue, suggesting there may be a problem with the machine after all.

"Also i will sit the detector on tge ground to dig and it wont quit beeping." I'm supposing that you search in discrimination mode. If you have the sensitivity (gain) cranked up quite a bit. When you sweep over the ground, the signal from the ground will usually overcome electrical interference or the machine internal noise floor, and the discrimination mode ground rejection system (which mostly doesn't depend on ground balancing) will calm down the noise. If you then set the machine down or if you stop moving the searchcoil (it's a "motion machine"), the ground signal no longer suppresses electrical interference and the machine will sit there and chatter unless you have the sensitivity (gain) cranked down far enough to suppress it.
