MD-7030?

[Beav]

Anyone have an MD-7030 schematic or know where to find one on-line?
This is the "Famous Trails Discriminator II" detector brand but Radio Shack also carried it under the 63-3013 part number.
Thanks to all!

Also schematic for the Famous Trails Challenger or the MD-1023 or the GD-1023 which is also know as the Gold Snoop. All these are the same detector made in China.
Schematics please
