Not only an oldie, but a rare oldie. In mint condition. Dual coil. Picks up ferrous in one coil, picks up non-ferrous in the other coil. Target ID by meter reading. Was a unit before VLF came out. Also before TID came out.
Jack Roach was a Rocket engineer with the US government. Roach made some earlier detectors out of his home. Then he contracted with Semtech, to have Semtech make the units. In the meantime George Payne came with his VLF ground cancel invention, and Semtech only sold a few of the units, and pulled them off the market. I believe this particular model was a "presentation case" given by Semtech to Jack Roach, as the FIRST Semtech model produced, as Semtech began to tool up for production... A few models got out to the magazines for field tests, beyond that, I am not aware of the models out in the public domain.
The unit even has the rare earphones and the even rarer sales flyer.
Who was this mysterious Mr Roach? Here this impressive person is:
"Mr. Roach has 30 years of experience in the following areas: missile defense, space surveillance, missile warning, missile crew operations, space and missile intelligence collection, development and implementation of Emergency War Orders, battle staff, nuclear positive control and coded switch programs, space launch, spacecraft command and control, mission planning, operational concept development, project management, requirements definition, system integration, test methodology development, test planning, test conduct, system evaluation, configuration management, software development, program advocacy, budgeting and programming, and Office of Secretary of Defense (OSD) oversight of Space, Helicopter, and Ballistic Missile Defense programs."
