Long hose, no he’s not bragging or being obsene when he say’s to grab his long hose during the buddy check. It’s a 7’ to 10’ hose on the primary reg that allows a diver sharing air to swim beside or head to toe exiting a wreck or cave. The donor goes to his octo since an OOA diver tends to grab the one in you mouth anyway!
