I agree. But human nature being-what-it-is : We md'rs seem drawn to always become starry-eyed and want to believe there's a better mouse-trap out there.
And why is it that most of the "starry-eyed" videos (and new-fangled inventions claiming amazing feats) seem to be coming out of Europe ? (Specifically Russian countries).
As for the amazing videos that circulate, well SO TOO could I make an "amazing video" , if I only used one of Minelab's GPX or GPZ machines. Then I too could show you a video where a quarter could be picked up nearly 2 foot deep ! Woohoo! Who can argue with depth like that, eh ? The worked-out-parks would "come alive again", eh ?
Yet as we all know, the devil would be in the details. There is no way you'd take that machine to the average park, school, beach, or ghost town. You would get a quick dose of reality. And You would quickly put it on the shelf, and reach for your standard discriminator or beach machine. Doh !
Exactly Tom... I keep hearing about the 7 uS that won't work up here... I can't even get a smooth threshold trying it at 10 so that selling point is moot...
