A case sturdy carrying case with a blue finish and aluminum reinforced edges and corners houses multiple component of a single instrument. The case is made partly of wood. The case has two locking latches and a black plastic carrying handle on the front face.
The following components are housed in several foam recesses inside the case:
– One console unit with a display and a grid of buttons on the upper surface.
– A sensor unit consisting of a white cylinder full of liquid. This has a coiled withe for attaching to the console unit, and a screw for attaching the unit to the tip of the included staff.
– Five cylindrical sections that can be screwed together to form a single staff. These are stored in a separate compartment in the case lid.
– One black battery harness. This features a belt and adjustable quick release buckle so as to be work as a belt. A coiled cable attaches the battery back to the console unit.
-One shoulder harness with quick release buckles that attach to the console unit.
– One battery charger unit with one cable reminating in a AC wall plug, and another cable that attaches to the battery unit.
– One cable terminating in a 9-pin serial plug. This may be used to plug the console unit into a computer.
– On AC white adapter plug to from for adapting Type A to Type C.
– One small green coloured metal container containing five fuses.

A proton precession magnetometer (PPM) detects the resonance frequency of hydrogen nuclei in the presence of a magnetic field to be measured.
These instruments are used in magnetic surveys. Common applications include mineral prospecting and the detection of archaeological features.
There is white corrosion around the metal jacks on the console unit.
