to demonstrate just that task at some seminars for a couple of prospecting groups.

Don't use the Tracking function.

In the Prospecting mode, with a slight threshold audio, Ground Balance to the general ground matrix that is near a wet or dry stream bed. This ground would generally be a little less mineralized than the more intense black sand pockets.

When you encounter a pronounced mineralization change, such as a pocket (area) of black sand, the threshold audio will null out. You can 'trace' the outer boundary of that more mineralized spot and then pan it , sluice it, dredge it, high-back it, etc., etc.

PS: There are a couple of other techniques to use with the X-Terra 70 and if interested you can E-mail me and describe the type of area you have in mind and your application. MonteVB@comcast.net
