This is a seismic sensor unit with settings for the detection of various types of vehicle or personnel. It connects to the related Monitor Unit via a wireless link using one of the related Aerials. The battery module that fits in the unit's top compartment allows it to run for many days, depending on the battery type.
The carry-bag can hold five of these sensor units, though the archive only has one.
The "E.B.L.R. APR 92" mark indicates that it was serviced at Rochester in 1992. The battery considerably pre-dates this.
