Gun is designed for situations where a few contact CP readings are required. The unit has twin elements for real-time self calibration, and dual ultra-bright LED readouts for use in dark waters or strong currents, where visibility is low. These standard Polatrak features provide an unparalleled level of accuracy and redundancy.

Gun is rated for use in depths up to 1000 feet (300 meters). The unit has a convenient power-switch and operates on two 9 Volt alkaline batteries. This combination will allow the user to stretch the 4-week battery life over an entire dive season.

The Gun is self-calibrating. Each LED is wired to a separate, individual reference element -- essentially two probes in one.

The Gun kit comes complete with operating and calibration instructions and a comprehensive supply of spare parts.
