Scenario:
Dive buddy team is conducting dive within recreational limits at 120’ when diver 1 begins suffering from narcosis. Diver 1 drops regulator and begins to panic. Diver 2 deploys 7’ hose and regulator to diver 1 and prepares for slow ascent to surface (no more than 30’/minute). Diverguard realizes that diver 1 is not breathing and begins sounding alarm. Diver 1 is still suffering from narcosis and confused by the noise, diver 2 cannot determine quickly how to disable system. Diverguard inflates Diver 1’s BCD at approximately 90’, moving him/her uncontrollably towards surface. Diver 1, still panicked, does not release Diver 2’s regulator and drags him to the surface also. In only a few seconds divers 1 and 2 move from 4ATM to 1ATM of pressure. Both divers suffer from Barotrauma and die on the surface.
