Entel HT840 Intrinsically Safe USTC Radio

The unique and advanced HT840 Marine radio conforms to all aspects of USTC certification for portables used in hazardous locations. It further exceeds this by being fully submersible to 5 metres depth for up to one hour - all other radios in this class are merely splash proof. In the harsh world of maritime and terrestrial high-risk environments why compromise?
