F70, how to use the threshold?

[KurtB]

Can the threshold be adjusted to desensitize the detector to small bits of aluminum and modern trash? I coin hunt in trashy areas. Is this possible to do with this detector? Seems like it might work.. Thanks for any thoughts.

In Trash the best way to go is to use the small coil. Hunt in DE Speed in trash that helps with the separation. If very small Stuff is detected you can lower the threshold or use a positive GB setting.

I haven't been able to figure that out. Thanks, John

do not pump the coil ALL the way to the ground while ground grabbing may raise the GB level from its actual level?

Either use the preset GB at 90 ....so just don't GB . Or use a piece of ferrite that GBs at a know number.
