The BTD-350 Marine Thunderstorm Detector has been designed specifically for use in the marine environment. Its structure has been strengthened to withstand the rigours aboard large vessels. All surfaces are coated with a marine grade painting system.
The BTD-350 reliably detects the presence of all forms of lightning, out to a range of 83 km. The unique quasielectrostatic operating principle gives the detector a very low false alarm rate and the unique ability to warn of the risk of overhead lightning, even before the lightning has started.
