Detector coil test meter, super rare device!

Sadly, my test meter has to go to make way for a new detector 'project'. Only a handful of these were ever built and I'm willing to let it go for basically the cost it was new. $1,000. + post if applicable. These were built by Don Brereton of Micronair engineering and are still the 'ducks guts' of coil testers. Simple 2 switch operation, on/off and hi/lo to switch between measuring small coils or large coils. Suitable for both VLF and PI detector coils. Simple digital readout scale. PM me for info or purchase.
