Abstract: A self-contained surface supplied air system preferably provided with backpack-wearable capability and automated setup functions for ease of use that is capable of recording valuable recreational and scientific data in an unobtrusive manner. The flotation tube process for the system can be automated to reduce setup time and electronically regulated to increase reliability and safety. The system allows recreational divers or their inherent equipment to be capable of recording valuable and reputable data in a manner that does not involve extra effort by the user. The disclosed system can use a miniature pH sensor design with automatic calibration for integration into the data recording device. In one embodiment, the novel hookah diving system comprises a portable body enclosing all necessary equipment and featuring automatic flotation tube inflation and deflation.

Abstract: A depth selector or current depth provider for use by a variable speed air system. As a depth selector it is preferably in the form of a rotary switch on the user interface for the air system. The rotary switch can have 3 positions for maximum depth selections, such as, without limitation 15, 25, and 65 feet. Other depth values and number of depth selections provided can be used and all are considered within the scope of the disclosure. A microcontroller of the system reads the voltage from the voltage divider created by the rotary switch selection to determine which position the rotary switch is in. The microcontroller uses this information to set the upper and lower pressure limits for the dive.
