摘要：
The invention relates to a method and system in connection with a wristop diving computer (1). According to the method, at least the pressure of a gas bottle (2) is measured and the pressure data is transmitted under water using a low first frequency f1 to a wristop computer (1). According to the invention, on the surface of the water a second frequency f2, higher than the first frequency f1, is used for two-way telecommunications between the gas bottle (2) and the wristop computer (1).
