Said to be a 1970 Fisher "model 70"

What were they capable of, depth-wise, on coin-size targets ? I'm assuming this was an all-metal TR (not a BFO), right ?

Hello Tom,

Actually, Believe the Fisher-Scope M-70 came out in 1967 is what I gathered from Fisher Scppe material. Plus, I believe the first to have an arm rest.

Beautiful model, I have several of these and in working order. It's TR, Fisher-Scope didn't make BFO even the earlier models were TR. This particluar. Model took a small round 9-volt battery, I'll dig one up and post it in a couple of days. These special batteries could be found on eBay a few year's ago, otherwise it'll need to be modified to operate with a regular 9 volt.

They had a chrome wire armrest, attaches to rear of grip. Very well balanced for it's era, I've researched who had the first armrest detector and this one is the earliest I found.

Depth, Like any TR in it's day not too deep. Tuner is .mounted above hand grip behind the intensitivy meter. I think this detector was ahead of it's time appearance wise.

Nice looking unit,
Paul

No problem Tom,

Here's a bit more information, I know some of Fisher scope TR models operated at 87 khz maybe even the M-70, and tuning drifted quite a bit requiring constant tuning. Wouldn't recommend it for iron laced sited, it's more for school/park detection.

Here's a pic of the required battery, 9-volt and eBay may still have them.

Take care,
Paul
