Depth master pinpointer

[Unregistered]

Hi All
I have a depthmaster pinpointer by detector electronics, who says they no longer repair or matain the pinpointer. I would like a schematic or if some owns one and knows how to reverse engineer it I will settle for the type of IC chip that is in it. I am fairly certian that that is what is gone

It only uses one transistor in an epoxy encapsulated module.

It was acually called a depth master super probe and it was a handheld pinpointer
