I understand and agree with the obligation to return ok signals. Do you really return the emergency signal? I would think that instead of returning the emergency signal, that you go ahead and deal with the emergency - the first reaction being to deploy your primary.novadiver:In my cavern course they teach that a light signal can be done on the wall and returned on the wall to prevent a diver from turning to ask OK.the way it works is very easy. The same signals are used,circle for OK,Slow back and forth for attention, fast back and forth for emergency. All of these signals are returned on the same wall as the guestion signal. this way the team keeps moving unless they really need to stop and help a member of the team.
