There has been a lot of discussion about an adequate (i.e. safe and effective 99.999% of the time) system for making sure all divers are on a boat before it leaves the dive site. Which of these systems would you feel safest with, and more importantly adhere to (that means no bitching about it to the boat captain or circumventing the system) knowing it is for your own safety?
Would you pay extra for a boat that used a more expensive electronic system?
