Diagram for B.H.

[silversmith]

Looking for a diagram for a "Big Bud Pro Select 220D" or that family of detectors, or, a lead on same.
I love this old beast, and would like to "play around" with it a little. Any help would be much appreciated, Thanks, Ron. zlron44@gmail.com

If you mean the circuit schematic, that info is not readily available that I'm aware of. For some early BH stuff, you can try a search on the patent info. I've found some info that way, but it was not specific enough to list parts values, etc. and predates the 220 by several years.

It's supposed to be "magic" and revealing how the "trick" is done ruins it. Thus, most all commercial detector makers do not normally release detailed schmatics of any of their products. Those you see on the web for thisa or that detector have come from former repair people or someone who laboriously traced it out by hand.
