Perhaps more than one person, working together as a team, double checking for each other? If one person gets lazy about something, the other is there to maintain discipline, and then all one can do is hope that both do not have a complacency moment at the same time.
Honestly, I will admit to diving solo enough that I am not going to preach to others about whether to do it or not. I would love to be in a team more often. However, since going CCR, the reality is that I am back to a lot more solo diving.
Hey, do as I say, not as I do!
