Original Item: Only One Set Available. Excellent condition 1944 dated U.S. Army Signal Corps mine detector set AN/PRS-1. It comes in the original chest that measures 28 x 15 x 9 1/2 inches. The AN/PRS-1 mine detector is a late WWII metallic and non-metallic mine detector. It used a 280 to 320 Mhz signal to detect non-uniformities in the ground. According to the technical manual, TM11-1151, it is meant to detect anti-tank mines buried less than 7.5 inches below ground.

The batteries from this set are still in the case, something we do not often see. Also, the resonator is not present in this set. The manual is present, though falling apart a bit. The handle for the detector head is unfortunately not included, and the wiring ends have been pulled out of one of the missing components.
