We use them routinely on any drift dive....by design, not by doing anything we shouldn't have. Helps your boat find you, and prevents (in theory) other boats from running over you. And that's a GOOD thing. There was a Divemaster trainee years back when I was working for another shop...first, she "independently" did a drift dive with part of the group (she was supposed to just tag along with the guide) and worst of all, she LOST her sausage on the surface. So, as the boat headed down the coast to more or less routinely pick up these 4 drifted-away divers, I spotted what looked like 4 coconuts a few hundred yards to the side.....THOSE turned out to be the divers, while the sausage, with nobody attached to it, went sailing happily away. Not a perfectly-executed dive, to say the least.
