PURPOSE:To check the action during diving and to utilize the same as data for treatment of a submarine sickness in the event of accident by providing means for storing and displaying diving depth information and lapse time information. CONSTITUTION:A diver pushes an external set button 2a prior to diving. Then a diving depth sensor 6, a water depth measuring circuit 7 and a time counting circuit 5 start operating. The diving depth information is displayed on a display part 3b and the diving lapse time information is displayed on a display part 3a at every 5min of the diving lapse time. The information are stored in an information memory circuit 9. The diving information are successively called out when an external set button 2b is pushed upon ending of the diving. The action during the diving is, therefore, checked and the data for the treatment of the submarine sickness in the event of accident is obtd. The effective use of the data in the next diving is thus made possible. |
