Yes I used it with the RAF, I dont think it technically belonged to our unit, we just sort of acquired it

I prefer good old binos, or super-nikkons. You get to see this sort of shit:

I remember using it in 1985. The IR bits were the most useful as the seismic sensors took ages to settle down if there was any background 'noise' like trees. Someone once told me that the seismic sensors could tell the difference between two and four legged targets. But that must have been a pile of cock or we'd have been overrun by Spetznaz teams dressed as pantomime horses.

Didnt it used to use sensors plugged into the small clansman radios. ISTR the sensors were IR, tripwires and trembler's

I'm fairly sure that the boxes just looked like 349s. Don't remember tripwires, just IR and seismic sensors.

It was a long time ago !
