The First detector I had.
It was ordered from the back of some Magazine back in the 70's!
I had borrow the $50.00 from my mother paying her back in Yard Mowing money I made around the Block.
It was called "THE CRUSADOR"
What a hoot.
I even received a single page Memeio Graph News letter for a Year I think.
That was Called the "Seeker"!
Running at 350Khz, it had ground penetration of some 5" max with the 5 Transistors used.
In my front yard in Tucson AZ, I found a 1953 Quarter the first 10 minutes of trying the beast.
I was Hooked.
Circuit was a double Colpitt type and it would drift like not tomorrow!
But It Found stuff and Lots of stuff.
