Fisher Classic Forum

I purchased this old Fisher detector at a yard sale. Maybe someone here can tell me more about it... Thanks for looking

Does it work?

See what the battery voltage says. You could install 1.5 volt battery packs and do some re-wiring.

Hi Don't waste you time trying trying to get it to work. Those units have vacuum tubes tubes which require special batteries available at the time. Also some parts "Capacitors" are all bad by now.

Keep it as a conversation item because it would cost a small fortune for it to work and if you did get it to work the end result is very dismal by today's standards unless your looking for landmines.

Neat item tho!!

I'll probably let him play with it....................john

Hi John,

What you have is a T-10 with the wooden coil and wooden shaft, Takes one 67.5 volt and one 1.5 volt battery. Yours is tube type TR series, The odds of yours working is 3-1 ratio with the T-10 model.

Surprisingly, They still make the 67.5 battery and the are sold on eBay. The larger 1.5 volt battery was discontinued but you can make your own but make sure it is at least 2 volts and no more because it will need two volts to power it up. That is what I found out with my T-10 units, Although they call for 1.5 volt it takes 2 volts plus the 67.5 volt battery to fire them up.

I collect vintage metal detectors, Most brands including Fisher Scope. Here are a few pics of fisher scope and maybe few units of Detectron are in there as well, Plus a pic of the batteries I use to get these old dinosaurs going. All of these vintage detectors do work with the exception of the Ray Scope.

Fill free to keep in touch if you need help, Would be glad to offer any assistance if I can.

It looks as though the serial number may be "1" on the unit I have which is a curiosity to me. It'll be fun to tinker with during the winter months and I will contact you if I have any questions....

Best wishes..............John in Virginia

Hey Paul your knowedge and collection = GREAT!

If it does use vacuum tubes then you should definately replace all of the paper capacitors because they're probably dried out and will short out upon applying full voltage for the first time which can damage other circuitry, "Re-capping" is a common proceedure in restoring old radios and other electronic equipment. The batteries are however still available through Eveready, but hold on to your hat, they can cost as much as $45.00 each! Might make a nice museum piece for a mining display though. Good luck. wandering Mike

Here you go, Dr Fisher himself used this model (image from the cover of the Fisher 2009 Treasure News):
