Ace 350 ground balance?

Can anyone with an Ace 350 tell me if it has the capability to ground balance? I'm guessing it doesn't as I cannot find any such info for this model on their web site. If that's the case, has that been an issue for anyone? I'm assuming you would have to adjust down the sensitivity to account for areas of high mineralization?

No manual GB Dave. I ran it full sens, all metal, all the time. No falsing problems, but I'm always out in the woods. :groovy:

Thanks charlives
