I can tell you from 1975 forward…before that someone else will have to chime in..NASDS always taught that your weight belt is released with your right hand, your 2nd stage is removed from your mouth with your right hand and your left hand is only for venting air from your bc so you don’t breach the surface after you drop your weight belt when it’s necessary to do an out of air emergency free ascent. When the 2nd edition of the text book came out they decided to leave then 2nd stage in the divers mouth for obvious reasons but instead you were instructed to release with your right hand and then point your right hand toward the surface. Air sharing was also taught with right hand control of 2nd stage and weight belt if necessary. In 83 it was beat into our heads on a daily basis about the right hand release and if you allowed any of your students to put on their belt with the buckle that released to the left you were penalized by towing two divers home while wearing their weight belts looped around your shoulders…..Part of this was for routine and part was so you learned to pay attention to every little detail of every little thing that your students did. When I did the SSI instructors crossover I don’t think it was mentioned. Most of the book was on how to make students buy computers and not sue you.
Doing it right should include some common sense, not just blindly following specs and instructions. .Gary D, AWAP on SB
