Suunto Mosquito with aftermarket strap and iDive DAN recreational dive computers Other names Personal dive computer Uses Dive profile recording and real-time decompression information. Several algorithms have been used, and various personal conservatism factors may be available. Audible alarms may be available to warn the diver when exceeding the no-stop limit, the maximum operating depth for the gas mixture, the recommended ascent rate or other limit beyond which risk increases significantly. Change Battery In Sherwood The Source Dive Computer Download The DataSeveral additional functions and displays may be available for interest and convenience, such as water temperature and compass direction, and it may be possible to download the data from the dives to a personal computer via cable or wireless connection. Data recorded by a dive computer may be of great value to the investigators in a diving accident, and may allow the cause of an accident to be discovered. A dive computer is perceived by recreational scuba divers and service providers to be one of the most important items of safety equipment. Use by surface-supplied divers is less widespread, as the divers depth is monitored at the surface by pneumofathometer and decompression is controlled by the diving supervisor. Many dive computers also provide additional information to the diver including air and water temperature, data used to help prevent oxygen toxicity, a computer-readable dive log, and the pressure of the remaining breathing gas in the diving cylinder. This recorded information can be used for the divers personal log of their activities or as important information in medical review or legal cases following diving accidents. For example, a recreational diver who plans to stay within no-decompression limits can in many cases simply ascend a few feet each minute, while continuing the dive, and still remain within reasonably safe limits, rather than adhering to a pre-planned bottom time and ascending directly. So-called multi-level dives can be planned with traditional dive tables, but the additional calculations become complex and the plan may be cumbersome to follow. Computers allow for a certain amount of spontaneity during the dive. There is no reason to assume that they cannot be valuable tools for commercial diving operations, especially on multi-level dives. Tempered glass and synthetic sapphire are most scratch resistant, but brittle, and can fracture on impact, causing the housing to leak, which can destroy the electronics. These materials are popular on wristwatch style units, which are expected to be worn out of the water. The larger units are more likely to be worn only while diving, and the more impact resistant polycarbonate faceplates used for these computers are more sensitive to scratching, but are less likely to flood. Disposable transparent self-adhesive faceplate protectors are available for some models. It may be rechargeable, or user replaceable, or may require replacement by an authorised agent or the manufacturer. The output may be recorded and displayed, but the primary function is to allow accurate pressure measurement. These computers track the dive profile by measuring time and pressure. All dive computers measure the ambient pressure to model the concentration of gases in the tissues of the diver. More advanced dive computers provide additional measured data and user input into the calculations, for example, the water temperature, gas composition, altitude of the water surface, 6 or the remaining pressure in the diving cylinder. When divers travel before or after diving and particularly when they fly, they should transport their dive computer with them in the same pressure regime so that the computer can measure the pressure profile that their body has undergone. This may be by way of a personal factor, which makes an undescribed change to the algorithm decided by the manufacturer, or the setting of gradient factors, a way of reducing the permitted supersaturation of tissue compertments by specific ratios, which is well defined in the literature, leaving the responsibility for making infotmed decisions on personal safety to the diver. The algorithm may be a variation of one of the standard algorithms, for example, several versions of the Bhlmann decompression algorithm are in use.
