Have had a gold bug pro for a year and generally was disappointed with it to the extent i was selling it. Had a guy interested in buying but thought i had better check to make sure it still worked ok. I am in very high mineralised ground and have always had trouble ground balancing the machine. Today i turned offf the discrimination and the machine ground balanced and ran stable . Well i it the park and was quite amazed This detector id,s brilliantly, and sorts amongst trash like a champion, I found you only had to have a flash of a target id amongst the trash and sure enough hiding in the trash was a coin . Needles to say after my 2 hours in the park i rang the prospective buyer and told him it was no longer for sale.
