My crack bottle dsmb and pocket reel fits in my BCD pocket.
Also, the old SMB suffered the neglect too common with backups and, thankfully, failed in test rather than when required. That is why I insist on the LP fill option as a fallback.
Especially when it's the DSMB carefully stowed at the top of the right hand pocket for when I'll want it.
I detect some resentment from you.
I usually have to meet people to upset them so much.
What's your problem?
I've also found that I can get my DSMB out of my pocket just as quickly if not quicker than unclipping it. I've tried both methods and prefer the pocket storage.
