Sea Trek (diving system)
In 1999 Sub Sea Systems, Inc., introduced Sea Trek, a recreational underwater free-flow open-bottomed helmet diving system marketed as suitable for people with no previous diving experience. Current Sea Trek operations vary in depth from 3 to 10 meters. The maximum depth is not a function of the system's ability to provide air supply (operating pressure of 80 p.s.i.), rather a function of what the manufacturers consider a safe operating depth for non-swimmers in case of emergency. Air can be provided from one of three options: The surface supplied compressor air delivery  is controlled by a microprocessor digital control system (A/C & D/C), providing the following primary functions: Sea Trek Underwater Wheelchair. A modified wheelchair was introduced by an operator in 2015 to take guests with limited or no use of their legs on an underwater tour. Sub Sea Systems developed a custom underwater wheelchair specifically designed to be used with the Sea Trek system. This program is called Adapted Sea Trek and will be available at multiple locations worldwide.
