Although not brand-spanking new, Dive Rite featured their TransPac at the DEMA show. The TransPac is a completely modular system, meaning it can be customized to fit any body type, and each piece can be replaced independent of the rest of the unit. Think of it like a high-end stereo with individual components versus an old-school boombox.
Made from 1000 denier Cordura nylon and featuring 316 marine-grade stainless components, the TransPac comes standard with 7 one-inch D rings; 2 two-inch waist D rings; 2 two-inch angled shoulder D rings; a Waist buckle; and Cam buckles (2 cam straps).With the TransPac, divers can easily switch from singles to doubles -- or even use side-mounted tanks.
Combine the TransPac with aircells...
...and you have a BC system that is built exactly the way you want it.
