Had a discussion yesterday with a shop owner/instructor about which wrist/forearm to wear dive computer. I was trained to wear it on my right wrist/forearm so that if one needs to vent using the corrugated hose with the left hand while ascending one can still pay attention to their ascent rate indicator on their computer on their right wrist/arm.
The shop owner/instructor was explaining to me that the computer on the left wrist/forearm puts it above the head while ascending and venting via the corrugated hose which helps contribute to keeping the airway open. He stated that with the computer on the right wrist the tendency is to look down which could lead to blocking the airway which can lead to pulmonary injury.
When I asked him where he learned/read that having the computer on the right arm increase risk of pulmonary injury, he pointed to one of his former students coming out of the water wearing a suit with a velcro tab on the left wrist to help hold a computer in place and tried to use that to further rationalize his statement.
My thoughts are that one should wear their computer however one finds it comfortable and convenient but it was interesting that this guy seemed to site what comes across as bs pseudo-medicine/pseudo-physiology reasons for teaching this to all his students.
In 24 years of diving I have never heard of this, I am interested to know what others are teaching or have been taught.
