New BountyHunter IV when set to disc mode, any sensitivity any disc knock setting from min to max I can not notch out a pull tab laying on the ground. Doing an air test I can notch it out just fine. What am I doing wrong?
You do realize if you notch out pull tab your also notching out a lot of gold. If you want to find gold your going to have to dig pull tabs, it is the nature of the beast..
Owning a Bounty Hunter and a Fisher which are now same company's. I would suggest you try different dirt types and see what happens. Air test are just showing the machine works. The targets in the ground are going to be different. Run at least a set of battery's to see if you are doing something wrong. It may help to run as low a sensitivity you can for a while.
