Do we have one on this forum who prcatices the dangling method I would love to hear from them?
Not exactly "practicing the dangling method" but I and other instructors/DM's I know (who dive 7ft config) will sometime switch to our backup and keep the reg end of our primary hose draped over our left forearm when we have students doing mask removal/flood/clear, reg removal/replacement, air shares with other students, etc. Pretty much any time there's a student that we think might end up losing/spitting a reg. I like being able to immediately offer a reg with one hand while controlling the student's buoyancy with the other if needed. This is hovering over a platform doing skills however, not during any actual "diving" portion of the dives.
