The General Proximity Electrode can be attached to a divers belt, providing potentials while he/she works.
The Polatrak Proximity Probe is designed specifically for diver use when conducting subsea platform services. Like all Polatrak probes, it has twin Ag/AgCl elements to allow on-line calibration. The Standard Seacon RM-3 connector allows rapid plug into the divers inspection umbilical.
This probe can only be used with a topside ground, it is a proximity probe only. Deepwater can supply a mating umbilical cable if required. The probe can be interfaced to small Eye-Ball type ROV's if required, but still can only operate in the proximity survey mode.
Corrosion Survey
For purpose surveys, divers can be equipped with a general purpose electrode, simply attached to their gear and wired up to the surface. Readings can easily be taken topside.

Dual Ag/AgCl elements (silver / silver chloride) allow for online calibration and planned redundancy, making Polatrak the most reliable brand of CP probe on the market.
The proximity electrode comes with a standard connector, but any sort of replacement can be fitted to interface with the diver umbilical.
The general proximity probe costs about the same as old-fashioned single element electrodes.
