The Baro-Diver ensures that you accurately capture changes in atmospheric pressure. one Baro-Diver covers a radius of up to 15 km, depending on the topography. The Baro-Diver can also be used for measuring shallow water levels up to approximately 0.9 meter. The Baro-Diver has an internal working memory capable of storing 72,000 measurements per parameter. For each measurement, the Baro-Diver simultaneously registers barometric pressure, air temperature, date and time.
