Interesting point. I recently did the well-worn (PADI) Rescue Scenario #7 again, for AI this time. Reading your post, I am left wondering what it would be like to get a tired/unresponsive diver out of a HOG harness, or get myself out while managing the diver, without those handy quick releases. Not saying it can't be done, or would be unmanageable, or any thing like that. But, I certainly need to practice that skill as well. Most of us in the shop tend to dive a jacket while doing an OW course with students, in order to have an equipment confiouration similar to the one the students are wearing, and we therefore practice with that rig. Thanks for the post.
