I’d echo the above. Saying you’re on your way out, it doesn’t need to be as polished is asinine.
Yeah, piling on to problems by ruining visibility and/or ramming gear into rocks ain't gonna help any or make an already limited gas supply last longer.
It wasn't my comment. I just shared what someone said to me. But, I feel like you are taking the statement "OC buoyancy doesn't need to be as top notch as what an OC cave diver would have" and interpreting then responding as if the actual statement made was "OC buoyancy can be crap."
My fifth and sixth dives after I finished OW were the two loops in Dos Ojos cenote. That is pretty shallow (i.e. harder to control buoyancy than a deeper dive). I somehow managed to follow the guide and the line all the way around both loops without ever touching the ceiling or the bottom - including not banging my tank on anything.
Does that mean someone with 4 OC dives has good enough OC buoyancy for CCR Cave? No. But, I submit to you that the buoyancy required to follow a line out of a cave, without banging into stuff and without silting it out, is easier than the buoyancy required to, for example, tie off a line correctly as you are going into a cave. It seems entirely feasible to me that someone has been diving enough to be ready for CCR Cave could very well already have good enough OC buoyancy that there is really NO reason to make them take an OC Cave class first. However, I have no cave training, so I could be completely wrong. I will have to rely on my eventual CCR Cave instructor to tell me if my OC buoyancy is good enough or not.
