Dont think many CCrs will understand that. May I translate?is shucking Scallops on the shotline at 9m doing Deco and slashing your hand the same as an oyster slip ? asking for a friend ...
1. After a deepish dive one has to do at least one decrompression (deco) stop.
2. One normally sends up a bouy on a rope then ascends on that rope......holding on at the eg 9 metre stop.
3. One may take those few minutes to open the oysters he/she has collected.
I imagine its not nice to slash your hand while having to spend 3 minutes hanging there.
