newbie questions

Welcome to the site! Glad you are here.

I take it you have read through the FAQFAQ at the top of the site? If not then I would start there. If so I am not the one to answer your question. I have never beach hunted, or used the prospect mode, Beale.
 
Beale,
Yes I have read the faqfaq at least 3 times, and i have read the posts on this forum up until page 66. The FAQ is very detailed on the use of the xterra and so extremely useful .
I'm by nature very curious as to the technical/engineering aspects of detecting, my questions in this post mostly operate from a why is it made that way, rather than I wish it was that way perspective.

I'll give you the executive summary that should answer most of your questions. The Coins & Treasure All Metal mode will signal on all types of metal but there is also quite a bit of filtering going on to reject the noise caused by the ground. The Prospecting Mode is what some would term a True All Metal Mode because much less of the ground noise is being filtered. This makes it much more sensitive to tiny targets like pieces of small gold. But to have ID would mean including more filtering which would be counter productive to finding small gold. There is a limited discrimination called Iron Mask to eliminate small pieces of steel & iron.

Tracking is faster in Beach Mode because there can be two widely spaced ground balance points to contend with. Saltwater which is conductive mixed in with Black Sand which is magnetic. The Black Sand usually lays in stripes with concentration varying widely which means the tracking needs to adjust the Ground Balance within inches, not tens of feet like on land. Yes targets can be tracked out if you don't learn how to use the detector.

Hopefully BB ansered to your satisfaction. I suspect you will be back with more ?s, I was. Do go thru the older posts and search seting up the machine, things like GroundBalance and Sensitivity and the interaction of Threshold.

Then go run it for a couple days and come back and ask more ?s. We all did (do).
