Might want to check ebay and maybe "google" it as well....

According to Jane's Military Vehicles and Logistics, the battery voltage is 16.2 V mercury battery, getting 28 hours continuous operation.

The Army sought to create a hand-held mine detector that would counter the
new dangers posed by nonmetal mines and, in response, fielded the AN/PRS-7.
However, in the midst of deploying these units, the Army recalled
all AN/PRS-7 devices because they were unreliable and error prone.

The AN/PRS-7, was superseded by the AN/PRS-8. The new solid-state transmitter and
receiver sweeps over a wide radio frequency band instead of the single frequency of the earlier
AN/PRS-7, and provides an order of magnitude increase in the search head data gathered.

The PRS-7 is a pre-1981 design and being that it used mercury batteries, new batteries may be
difficult to impossible to obtain. You may have to improvise a new battery pack.

The "state of the art" now a days is the AN/PSS-14, which features a metal detector, together with
a GPR, all in an integrated search head.

"Unreliable and error prone".......just what you want to hear in a combat zone!!!!
