Absolutely. This used to happen to me all the time, and I was always having trouble keeping track of where my octo is, where my buddy's octo is, where even my buddy is. I am just trying to figure out some of the finer points about the hog rig, like the "you know what gas it is" argument. Maybe it will make more sense to me, when I actually do deco diving.I would think it's quite practical to not be giving an OOA buddy, who may be on the verge of panicking, a crappy, old, hard breathing regulator, that might be dangling in the wind when he actually needs it. How many times have you seen this? Too many times to count! A necklace makes this scenario impossible. That's quite practical.
