lobo super traq ground balance

[azdave35]

Is there a trimmer on the Lobo ST that adjusts the preset ground balance in discriminate mode?

I asked this question repeatedly myself but never got an answer.Recently on another forum I finally found some facts.Adjusting the GB trimmer apparently requires the trimmer(s) affecting discrimination to be reset also which can be tricky.I popped the case off mine and had a look;I counted seven trim pots and gave up the idea.If you want to go to a larger than standard coil you have to have the factory reset the detector for you.None of this is easy enough to be practical.
