Here is an AT-Pro video I made last summer to demonstrate the VDI numbers on various Platinum, Gold, Silver, Stainless Steel, and Tungsten rings.
For the already knowledgeable user this video will probably not offer you anything you do not already know, the video is made for the new ATP user...of which we have a few in this forum.
This is basically an air test, the targets are on the ground, not covered. So always remember this, soil conditions and depth of the target can and in many cases will change the VDI numbers
slightly. I personally always run my ATP's just the way it is set up in the video...PRO Mode, with Zero Discrimination, and Iron Audio "Off"....this is my preferred method, I listen to everything that
is under the coil and determine by sound, then by numbers whether or not to dig the target.
Good Luck and HH
