Abstract: The invention relates to a device for analyzing a dive, comprising at least one first arithmetic unit which is intended to be carried by a scuba diver during a dive. The first arithmetic unit is connected to at least one sensor that detects dive-specific parameters. The second arithmetic device comprises a memory device in which dive-specific data can be stored, the first and the second arithmetic unit comprising respective data communication devices. The arithmetic units communicate temporarily with each other to transfer dive-specific data from the first to the second arithmetic unit.

Abstract: Display device for displaying information during a dive on a dive computer. The dive computer comprises a screen, measuring devices that detect variables related to the dive, a memory device to store data and program steps, and a computing device that processes the measurements made by the measuring device and derives data therefrom. A plurality of masks are stored in the dive computer to arrange dive data on the screen. The computing device determines characteristics from the dive data to select the mask characterizing the dive situation.

Abstract: Dive computer with at least one measuring device for detecting measured variables, at least one memory device, at least one computing device, at least one data transmitter, and one display device for displaying information. The memory device has at least one first area and at least one second area in which data are stored that are allocated to at least one first or at least one second user. There is also a selector for selecting the user to whom the data currently detected by the measuring device are allocated.

Abstract: The invention relates to a case for a dive computer that is worn by a scuba diver during dives. Said dive computer comprises a display device for displaying dive-related data that are visible from outside the case, actuation devices of the dive computer that can be actuated from outside the case and fastening devices for fastening the dive computer on the scuba diver or on his/her equipment. The case interior of the dive computer is configured in such a manner that the forces acting upon the dive computer due to the water pressure are compensated to at least some degree.
