no, that's not my machine. I just found the pix on the net, and transported them to insert here
I talked to a fellow from southern CA, who said that in about '64 or '65, he saw someone with one of those on the beach (probably only working the dry sand, 'cuz I doubt they'd have worked on wet salt). He thought that looked interesting, so he went about trying to find where he could buy one. Pretty soon, he too was the owner of a Metrotech. He said that there were quite a few of them on the beaches there in So. CA, but he soon learned that he could do quite well doing sandboxes around Los Angeles and the suburbs. He recalled that in a few hours, he could usually have himself $3 or $4 in change. That would be enough to fill his gas tank (go figure, gas was probably still .25 p/gallon?) and get a 6 pack of beer. Sounds silly now, but back then, when minimum wage was only $1.25 p/h, this was "serious money" for a college age kid
And as virgin as things probably were then, he says he never had the presence of mind to try exotic places. Ie.: stage stops, forts, historic monuments type places, old-town urban demolition, etc... He said he simply looked at it as only something to work sand, and only for current coins. Of course, those "current" coins at the time were all silver. But it didn't occur to him to save them, as they were still spending those coins, as the time.
I never got to actually handle one, and never saw one in action (I started in the mid 1970s). Thanx for the info you have that they could get around 6 or 7". That's pretty respectable for that era! Ah if only we could go back in time and know what we know now about hunting sites, and have something even as primitive as that
