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.
Key design points
Twin electrodes
Replaceable, dual silver / silver chloride (Ag/AgCl) electrodes provide real-time calibration, and allow the dive to be completed even if an electrode fails.
Battery life
The CP Gun™ uses two standard 9V batteries, which are easily replaced in the field. With its convenient on/off switch, the batteries can last the entire dive season.
Serviceable
The sturdy design of the CP Gun™ probe allows easy replacement of worn or damaged parts without having to replace the entire probe. It can be serviced easily in the field.
Bright LEDs
The CP Gun™ is the only diver-held probe with bright, backlit LED readouts that help the diver see CP readings in low-visibility conditions.
