@lukeb , I looked at the diagrams - they make sense, probably because I was taught that way... The diagrams imply that the "thick" REM side points to the exit. Not sure if that is entirely correct, as REMs are individual markers and some divers may choose to use the "thin" end to point to the exit. Explaining these options in the diagrams would have been better.
