Rick, even if this did accomplish usable discrimination (and iron rejection), I can think of one downside to the "super-sensitivity" of pulse machines, that sometimes turns out to be a "downside".
For example, I toyed around with a Nox 800, thinking I was going to angle for micro-jewelry on a certain dry-sand section of a millionaires beach. Gotta be some dainty chains or earring studs that all those standard machines have been missing all these years, eh ?
And sure as heck, I NEVER LACKED FOR TTTEENNSSYYY things to choose from . Wooohoo. I could practically FEEL the tinsel thin chains and diamond earring studs that would soon be jumping out of the ground and into my pouch . Eh ?
But after an hour of digging TTTeeeennnsssy foil turds, pinhead cr#p, etc.... I began to think "Gee, do I really want micro-jewelry *that* bad ?". I mean, heck, what's the intrinsic weight of a tinsel thin chain after all ? DOH !
POINT BEING : If a person DOESN'T want the "bells of Notre Dame" to scream off of every birdshot item, can he set this machine to respond as normal machines do ? Or is this "super-sensitivity" just hard-wired in ? At least, on the Nox, you can set the controls to mimic standard machines, where it's just going after normal coin and ring sized stuff (and will miss a ttteennnssyy foil turd).
You know the old saying about beach pulse machines: A) The "good news" is that : They're so sensitive, that you can find a bobby pin to a foot deep !, but B) the "bad news" is that : They're so sensitive , that you can find a bobby pin to a foot deep. Doh !
Thus, if someone didn't want to be bothered with insane teensy stuff, can he make this machine react more like a standard coin machine, versus the usual pulse insane sensitivity ?
