I picked up this British mine detector at a militaria fair a couple of years ago because it looked interesting and it was reasonably priced. I don't really know much about it other than it's British and post WW2. I have no idea if it is in working order or not. It seems like a heavy thing to hold for any length of time.
Well, it LOOKS like the ones we had, I thought ours were US castoff. Not too sure as I didn't have the Pioneer course. We were issued for a range cleanup in 1981 and used them for a week or so... Yes, they are a bit awkward but so is much of our gear. Example, the handle should have folded up from the other direction and it would have been easier to keep in position... You can buy simple metal detectors now that are head and shoulders beyond these. Does this not use a couple of "D" cells?
It may do Jim, I'm not sure what batteries it's supposed to use.Quote:

I’d be curious as to it’s capabilities just for the fun of it.
When we were using them, they didn't do much at all. Sometimes couldn't "Smell" a shell when you held it to one.Quote:

I think they go into the box after removing those proud screws... Then I stole the picture appropriate...
Yes, modified from the old WW2 valve driven UK spec Detector, Mine Mk5 which was transistorised to run on 9v instead of the dual volt valve set type*. I don't think that the one shown is a UK version due to the 66 VAOS number (ours were 99) Our search coils had 2 settings too, PAVE and GROUND - for roads and other stuff.
I borrowed one of those in the 70's to help a group of aircraft people to search for the wreckage of a Liberator near to Shefford Woodlands near Newbury because so said, it would search deeper than the usual civvy stuff of the era. All we found were loads of bits that were found to be the remains of a troop carrying glider that cut its tow, and smashed itself to smithereens as it came to land, hitting some trees as it did. Some rusty rifles, radios, a pistol still in the holster - all rusted solid.
Ours, as I seem to recall, ran in 2x brown, square batteries with screw threaded terminals. Batteries were 1.5 x 1.5 x 5" deep with central earth terminal and the live terminal at one corner. Same as used in the Vickers GAP set-up. That's all I remember about them. Repaired by the CET's - or control equipment teccies
I think the original ran on 120volts DC - as per the old home valve radios of the era
Still in use late 80's early 90's and part of the standard Royal Engineers G1098 Stores.
Thanks for all of the replies chaps. It looks like, from the terminals, that I need to try the little 9 volt battery commonly used in smoke detectors in the UK.
I would have been surprised if Peter hadn't had to handle these, or maybe it was your version of the ELM techs that did it... One of you would have to inspect them though.
Road clearing operations were common missions in Viet Nam. Engineers would often be assigned and were commonly equipped P-153 mine detectors. AN/PRS-4 detectors were universally despised as to difficult to keep adjusted and difficult to use with soils that were rocky, although they were touted as being capable of finding both metalic and non-metallic mines.. The metallic mine detectors were simpler, but on roads which had seen combat since the days of the Japanese occupation, shrapnel, brass, machine gun links all worked to confuse the operator. Another factor was the common bamboo trigger switch used by the VC had little metal in it and it took an attentive operator to find one. Lastly, the sweepers should have been switched out at 20 minute intervals to keep them from going "tone deaf."
DETECTION AND AVOIDANCE OF MINES AND BOOBYTRAPS (1968)
The tank made a pretty good mine detector, if they were not huge. However, much to the dismay of truck drivers, wheeled vehicles exert a ground pressure equal to their tire pressure. The M48 tank only exerts 11 pounds per square foot. Quite often trucks would set off mines tanks had not.

Very staged you can see...the man handling the mine at the end was very ham handed. Nothing more frightening than another guy's explosive device.Quote:

Yes spotted that too Peter, strange times, especially as they were normally assigned to a SNCO:)
I watched the catchup on Peaky Blinders last night with his Thompson and drum mags, and his drills. Clearly no idea about picking up his drum mag when empty........well I suppose it was in his mine field!!!
I have now sourced the 9 volt battery and fitted it into the compartment in the rear of the control unit/box. After turning the unit on, all that I could hear was a very slight, feint hum out of the headphones. I therefore do what I normally do in such situations, had a fiddle and, in this case, twiddled the 2 knobs on the control unit which made no difference. I then noticed that the brass jack plug on the headset lead looked dull and tarnished and so I thought that I may as well give it a clean up with Scotch-Bright cloth to see if that would make any difference. I was amazed to find that the mine detector appears to work perfectly at detecting a metal wrench and I was also amazed at the volume of what was coming out of the headset compared with before I cleaned the jack plug. I also have the user manual and the log book that has never been used.
Never saw a log book before, couldn't imagine why I'd use it. Careful with the electronic connectors, we used a pencil eraser to clean them, not harsh abrasives... One thing you can't be sure of, is if a piece of surplus gear even works in the first place. Here you are trying to figure out something that's unserviceable in the first place...sounds like yours has some promise though. Bury some coins at regular intervals in the garden and have a go...until you have it figured out.
Probably Sensitivity and Discrimination functions. Does the manual mention "Ground balancing"? Just curious if it's equipped.Quote:
