The handle comprises an upper section, which includes an electronics module, and a lower
extension tube. Correct connections are clearly marked on the electronics unit.
The probe is connected to the handle electronics module via the supplied 50Ω TNC-TNC cable
which passes up the inside the tubular parts and emerges at the top through a liquid tight rubber
gland. If required the cable can be retracted to facilitate connection of a probe to the top section
of the handle alone.
The probe cable can be replaced by removal of the rubber gland and a replacement part fitted.
The handle is submersible in water up to the electronics unit (0.6 metres). Extension tubes can
be provided for a limited increase in length.
Caution: Probe types MS2D and MS2F must be used in conjunction with the handle.
Accidental direct connection of a probe to the MS2 meter will result in excessive current
drain but will not cause permanent damage.

The field survey MS2D is a circular sensor, with a large effective measuring volume. It is
intended for use on flat surfaces where pinpoint accuracy is not required. It is used with the MS2
probe handle and will not function without it.
