Fisher 442

Does anyone know anything about the Fisher 442, I believe it was introduced around 1979?

All metals only machine, pretty sure it had a DD searchcoil, fully static (non-motion) operation. U-handle mechanical design, as were nearly all machines of that era. Simple, easy to use (once you learn how to do manual ground balance). Air hots on coins on the order of 7 inches. In its day it was a good solid design, though unexciting.

The engineer was Jim Jones (no relation either to the Guyana massacre guy, or to Marvin Jones, another Fisher engineer who is still with the company). Jim Jones was an Englishman and was an engineering consultant, not an actual company employee (as I understand it). Only met him once in person. Very good engineer. ....... The 442 legacy lives on today (with some minor variations) as a couple of our industrial valve & box & rebar locators. It may seem odd that a mid 1970's electronic design would still be kicking around but it does the job for our industrial customers and they keep buying what they know works.
