So true. Divers having fun simply avoid unfavorable circumstances. Commercial divers are there to get a job done safely, efficiently, and on time for their client; or they will find someone who can. This results in conventions that are not applicable to recreational divers.
For commercial diving contractors, it is less about litigation liability and more about good business. Exaggerated payouts are limited by the Jones act in most cases and big insurance companies do the battling. Sure hurting employees may raise insurance costs, but it also stops the job and that costs contracts. That is what justifies the equipment and support investments to stockholders. This is not to imply there isn’t a driving human side. There is a near fox-hole sense of comradery that develops when lives are so interdependent.
It also doesn’t mean one discipline is superior to another. It is just different. Most commercial divers could care less about their SAC rate, the names of critters, or the ability to hover. A lot of them are useless in Scuba and would rather go through table 6 than use it… OK maybe that is a slight exaggeration. Table 4 maybe.
