Can anyone ID this vintage detector ?

Saw this on craigslist near me. At first I thought it was a Metrotech. D/t it has that metrotech style body/housing. But looking closer at the decals and writing, it has some different name written on there.

Anyone care to take a shot at ID'ing this ?

You will have to click on the image to enlarge. But once you do, you can read the writing.

Does the handle come out like a metrotec?

Wonder if it was maybe a pre metrotec or one made by them for someone else, looks like it with no meter, bet Paul in CA would know.

Tom, Google the name Curt fisher underground explorations, there's all kinds of links that come up.

One said he was the brother of the guy that started fisher metal detectors?

Good luck

Tom,

First time I've seen one if these, sparked my interest but then I seen METROTECH 220 on the side casing.

Looks like a modified Metrotech 220, processionally altered by Fisher? I like Jerry's reasoning he picked up from research.

I wonder if Fisher modified these for prototypes, if they made the grade from it's field testers then would be completely redone and sold to the public or for industrial purposes?

Is it still for sale, how much? I'd like to purchase it if I can.

Great post!
Paul

You're right. Now I see it. I can make out the "220" now. Hence yes, this is a metrotech 220. The decal had thrown me for a loop, and I wasn't paying close attention to the other writing.

Ok, let me see if the CL link is still there. Pop the guy an offer, and it'll make for an interesting conversation piece , since it has the odd-ball sticker on there.

ok, here it is:

The guy says "Santa Cruz pickup only".

So if he accepts whatever you offer him, I'll pick it up for you (am only 45 min. from there). And can hold it for you till next time I see you. Or can box it and ship it to you.

Let me know. It'd be fun to fiddle with it before sending it to you :)

Got your PM. I'll pick it up for you, and ship it off to you. Will be fun just to have a closer look at one. And funner still if it can actually power up. Odd-sticker aside, this is apparently just a 220. But it's amazing when you consider that this came out in about 1963 or '64. And while primitive @ today's standards, apparently could pick up a coin a few inches deep. Imagine being able to go to Bodie with this, back before laws existed that said "no", haha

Wonder if anyone back then had the presence of mind to do exotic places like that ? I talked to a guy who got a 220 in about '64 or '65, and he was doing quite well just hitting sandboxes. Silly by today's standards. But go figure, in an era when minimum wage was still probably only $1.20 p/h, then detecting for loose change wasn't so silly. Doh!

Thanks Tom,

Apparently it works, plus he's tossing in another same type unit but that one is damaged.

Appreciate this Tom, amazing you came across this odd one. These are tough to swing, I've got one or two Metrotech 220 Models but never seen this modified version.

Thanks again,
Paul

Ok Paul and other vintage buffs, I got arranged to pick up the machine in the next couple of days. The guy doesn't know where it's origin is from, as he only got it from an estate sale.

When I get it, before shipping it off to Paul, I'll do some videos of air tests with coins . And post them to Youtube. Because I see that at present, the only youtube clip showing a metrotech, is just someone showing it with a man-hole sized object. I'd like to see one done with coin-sized objects.

These were popular with CW guys as far back as the 1960s, and were popular on So. CA beaches back in the 1960s. It would be interesting to see what they were capable of, from a coin-hunting perspective.

cool Tom,

That would be great it you could muster out a video, but remember these are tough on the wrist.

JB had one back in the sixties, he often mentioned this before he passed.

I've had a couple myself, but never any of this modified version.

Thanks Tom,
Paul

Here's another Craigslist odd ball Metrotech 220 find
Posted by: Old California
Date: August 18, 2016 10:41AM
Tom,

I found this a couple of year's ago off Craigslist, Metrotech 220 processionally modified with a White's TR coil. Has a short somewhere in the shaft, never made time to correct this but whoever mounted the whites coil knew what he was doing. Swings like a feather, the smaller coil makes a difference.

The two red cannister Detectors in the background are FisherScope 1968 T-30 models, very similar to Metrotech 220. With the exception FisherScope staged the handle more to the center of the cannister while Metrotech continued to mount theirs on the bottom portion of can.

With the T-30, FisherScope apparently went with a model similar to Metrotech 220 but several years later, both operate the same both extremely hard to detect with for long periods.

Wish JB was here, he hunted with one back in early sixties. He would have jumped in and shared his Metrotech 220 adventures.

progress and question

Hey Paul, still fiddling with these cool units. Got swamped at work, and haven't forgotten that they'll get in the mail. I want to post some pix for vintage fans (in addition to pix that you intended when done). And hope to get one working, so that I can do a youtube video on their reaction for coin-sized objects. The only video I see of them in working mode, on Youtube, is a guy demonstrates one over a manhole cover. Hardly representative of their ability on coin-sized objects, doh! :rolleyes:

An interim observation I've made, is that the date is clearly stamped on the inside. Of the month and year of manufacture. And then comparing that to the little tag/plate on the outside (the serial # plate) you can see a 2-digit code that now I see corresponds to the year of manufacture as well.

That being the case: These two metrotechs are 1971 and '72 respectively. I had hoped to have an earlier one from the 1960's (as these came out in about 1963 if I recall). But I suppose they never changed in all those years, right ? So whatever these are capable of, it's assumed that the earlier years could do the same thing, right ?

Ok, and question for you Paul (or anyone): I have a set of headphones that .... when I use a splitter (like if I want a buddy to hear what I'm hearing during training), that the sound comes through in only one ear cup. What wires do I solder together, in order to get the sound in both ears ? Or can I just put a connection sleeve or solder connection, on the headphone jack, to bridge the gap there ?

Hello Tom,

No hurry, enjoy your free time and when if you can share with us.

As far as I know, the earlier Metrotech models didn't have an on/off switch. Plugging and unplugging the headset was the on/off feature. Later models, had an on/off switch and probably more advanced electronics wise. Also, I have what I believe to be one old Metrotech coil with the tuner on the coil itself, if it is Metrotech boy that's going way back before putting the tuner on the canister near the handle.

Plus,I wouldn't try using s splinter for the headset plug, please remember this is the main power source and you may case a surge of short using a modified connector.

No hurry Tom, I'm very excited you managed to find these and pick them up.

Thanks Tom!
Paul

Paul, will get those 2 metrotechs shipped out to you, as soon as work slows down here.

As for the headphone question, I guess I fuddled up that question. The 2nd part of the post, was not related to vintage machines. Doh! Am not intending to use a head-phone splitter on the metrotech. Probably should have made a separate post on a "tech forum" :) I just asked here, because I know that in all the year's you've collected and restored vintage detectors, that you've become good with tinkering as well.

Here's a pix of the headphone jack on the UR-30s. As you can see, it's split into 3. So to get the sound to be heard in each ear (for a minelab explorer using a splitter), which 2 of the 3 sections get "bridged" ?





Thanx !

PS: Thanx for the 77b advice that they do NOT use 9 volt batteries. I can see how it would be an easy mistake to make, because the connections are the same exact type that fit 9 volt batteries. So I just got to to to Radio shack and get a couple of those 4-pod AA battery holders. Going to see if I can bring this 77b to life. Hopefully the prior owner didn't fry it with too much voltage.
