While I agree with this up to a point, it would never happen. They got away from the old school way because the exclusive militaristic mindset of survive or die wasn't meshing with the mindset of the new regular civilian public that wanted to learn to dive. Diving was suffering in attendance and graduation because too many people were being excluded. So around the early 80's the top powers got together and decided to give the image and training protocols a change, I understand that. However, to the point that training deteriorated in some pockets of the industry is pretty disapointing.
I think they concentrated too much on profits and growth throughout the entire spectrum and getting these people properly trained took a back seat.
So now we have a debate here about donating the primary and the discussion goes to all the other problems that divers could face doing this, reg muggings, panicked divers, tanks coming loose because of faulty gear designs, hose configurations wrong for primary share, etc.
My feeling is that the primary donate isn't really an appropriate solution to anything until many of the other issues with divers' skill are addressed first. I see the primary air share as kind of a bandaid to bad divers skills.
My problem is I'm not seeing the primary air share they way they are claiming it will work with any configuration to be a better solution to share air. I think the panicking OOA diver and the reason they are an OOA panicking diver in the first place need to be addressed first. After that, I'm not seeing why SSI can't take the lead and become a proactive leader in changing the industry to a properly configured primary donate system, if that's what they want.
The way they are proposing now seems to me to put both divers at risk worse than the current standard octo method. Everybody needs to pick one style then teach it really well, it got way too fragmented.
