Polatrak CP Gun

The CP Gun is the most user-friendly diver-held cathodic-protection probe on the market.


The CP Gun outperforms all other available bathycorrometer-type devices in accuracy and convenience. Longer battery life, interchangeable freshwater / seawater electrodes and ultra-bright LED displays (for limited-visibility conditions) make the CP Gun the most user-friendly diver-held CP probe.


A single set of disposable alkaline batteries provides up to 150 hours of continuous survey operation. A convenient on-off switch allows display only when actually probing for even longer life. The CP Gun is rated to depths of up to 300 m (~1000 ft).The CP Gun is designed for situations where a few contact CP readings are required. The unit, like all Polatrak probes, has twin elements and dual readouts. This provides an unparalleled level of accuracy and redundancy.
