My gear also has a lift bag (in a Dive Rite pouch attacked to lower rear of BCD harness) and a reel (I use reels made by Larry Green - you can purchase them yourself through Joel Silverstein’s company Tech Diving Limited) and a whistle (Fox40). If your Dive Mask has coated lenses (I have contrast lenses with a special coating on the glass) then you don’t need a signal mirror. The mask can be used as such. If you are on an expedition then a personal EPIRB becomes a requirement. If you are simply exploring a remote location then a Pinger becomes your only real hope (these are so freakin’ cool!).
On that note, I also never wear a snorkel. My snorkel doesn’t have a purpose at 30 FSW any more than it does at 300 FSW. I don’t snorkel - I dive. If I’m diving Recreational then my AI computer keeps a firm grasp of my air and I have no excuses for running out. In a current a snorkel will turn your mask completely sideways on your face. Get a folding snorkel and for those of you with pockets feel free to keep it in your BCD pocket. If you are diving Lake Travis or what have you then a snorkel can be worn without causing issues but if you are diving the Gulf Stream and it’s ripping then in no time your mask will be cocked on your head like a gang-bangers hat.
Constructive discussion is welcome. Calling me out for being different than you with no logical sound reason is simply unacceptable.
