When I was about 30 years younger and using the old BFO's, I noticed the detector would scream over foil wrappers and immediately realized that detector signals would react to certain metals differently and always wondered why the reflectivity couldn't be measured on targets. I accidentlally, out of curiosity, started reading about the new white's and couldn't believe my dream had materialized. My question is: when you come over a sta-tab, or for that matter, any tab, are the aluminum readings noticeably higher on a sta-tab or regular tab versus nickels and rings? Any more info that would "make my day" and cause me to let go of a $1,000 smackers would be appreciated. Also, are any other detectors this capable? This is just awesome news to me. And many thanks.
