oh pullleeeasse, tell me that video isn't serious. To put a penny on top of the ground, and demonstrate a machine can pick it up? Well I sure as heck HOPE it can pick up a penny on top of the ground. Doh! Sure, for all those posts/people who say the "250 is a poor wet-salt machine", they never said it can't even pick up a penny on top of the sand. And sure, if you hold it high enough, and have the sens. down low, I don't doubt you "won't false" (assuming the minerals aren't too bad there, is another factor).
But that video doesn't say anything about how it's going to get it's b*tt kicked when chasing deeper coins in the wet salt, when stacked up against a Sovereign, Explorer, Excalibur, Whites 6000 Di pro, CZ6, etc...., etc...
I hunted side by side an ACE 250 user, on a white sand beach (low minerals), and yes, like the video showed, it will find shallow stuff. The top 5 or 6" anyhow. But the fellow couldn't get a peep on the deeper ones I flagged for him to try.
