Old Metal Detector used in the 60"s.

Thought you guys would like to see the metal detectors that were used in the early 60's.
This is a Metrotech 220 metal detector. It operated on a 9 volt battery. There was no
on/off switch as such. To turn the detector on you plugged in the headset and unplugged
it to cut it off. To ground balance the machine you used a wooden popcicle stick to turn
the screw on the coil head. When you could no longer hear the tone, the detector was
ready for use. The sensitivity dial was used to determine the size of the object under
the coil. A lead bullet would show a 5 and a brass buckle would show a 20+. The
trouble was there were so many objects in between these two items, one had to dig
every signal in order to not miss something good. I receovered several U.S. buckles
at 9" but most items recovered were in the 1" to 6" range.

Should have added...A piece of aluminum pipe was used to make a handle and covered in foam. It was then attached to the detector handle and shaft. The small handle would kill your wrist after a short time hunting.

I must say 9" on a belt buckle is awesome and what a name "Metrotech" you gotta love what each decade into the future has given us and who knows what the next 10 yrs will bring. Thanks for sharing I love things of the past.
Cheers!

Thanks everyone...was hoping you would enjoy the post.
I sold the Metrotech I had in the late 70's. Last year while walking through a flee mkt. I found this Metrotech 220 and the guy was asking $20.00 bucks for it. I purchased it and found that it still worked. I contacted Metrotech, who are still in business and talked to an employee who remembered the 220. He then told me that he had one new coil left for the 220. I purchased the new coil for $50.00 bucks and now the machine is like new. Finding this old Metrotech rekindled my interest in metal detecting which led to my purchasing the X-Terra-70.

Wouldn't it be great if we could take an Xterra-70 and sneak back into the 60s for a month or two?

It's better than an old mine detector! Nice shape, and well cared for. It's where We all started and were happy with what we had!

OMG! You beat me to the post!!! I just found one of these Metrotech's in the roof whilst cleaning last week!
The original "bag" is a Samsonite with a foam insert which is in the scrap heap to be thrown out since it's all rusted and busted.
The detector is in great condition though.

Original coil is bright yellow. Will post a pic for you to compare.

What an AMAZING coincidence!

Cheers,

Marco

Here you go! Made in 1967 I think. Very interesting to see how the unit folds down. Even the coil cable is concealed within the shaft!

I thought this might have been the last of it's kind. Apparently not!

Cheers!

Marco
