Just finished my sidemount course 1 year ago, as the sidemount dives more, the more I realised that a better understanding of the design concept of a sm system is important. My course was conducted in warm water with Hollis sms 75, but my instructor used a Razor, and that course just taught you basic skills and principles, no further introduction on the design of Hollis sms 75. So even now I don't know the functions of some parts of my sms 75.
For example, what's the function of rail system on the butt plate and armpit Drings? Some people say the rail system is just to attach more cylinders but I wonder that is it only be used to take more cylinders? And, American style sm often have 4 Drings on the shoulder strap, but Razor and some DIR BP/W only have 2 on it, so I want to know its function.
In addition, we know that Razor and xDeep have a butt mount pouch, but I don't see Hollis, Dive Rite and Halcyon sell that pouch. Is butt mount pouches common in the cold water areas using American style sidemount systems? Or is US style sidemount users have their own ways to carry backup items?
Hope have a discussion, thanks
