recently during Jan 2013, my wife finally overcame the worry of diving. now she is pretty well in the open water except during 2 incidents, which had happened during her 1st and 2nd night dives with an instructor.
before we went for the training of AOW of SSI, we have went to Tulamben for shore dives, which was 3 dives on the 1st day and 2 dives on the 2nd day. After that we break for one day before heading for night dive. the following day, we went for 2 deep dives, which was around 33m and followed by a night dive. next day, we went for 2 deep dives which was 38m.
During her day dives, she use 10 pounds of weights and with the BCD deflated, she is negative buoyant.
But during the night dives, she was unable to sink down during the 1st night dives, and was given additional 2 pounds of weight. during the dive, all of a sudden, she became positive buoyant and shot up like a balloon and i went up to catch her down to 10m.
During her 2nd night dive, she used a total of 12 pounds, and after her safety stop, she became positive buoyant again...
Both of the cases, she is having 80 bar of air left, after the dives.
is it due to panic?
After a week later, she got decompression sickness... which i think, it's caused by the positive buoyancy.
It can't be caused by the deep dives, as we were within the no decompression limit, went we are left with 2 mins, we proceeded to ascend.
