Beyond the choice of a MC buoyancy system, consider how you can streamline or improve your gear with the right dry suit accessory, attachment hardware, or stage or primary regulator hose kit.
Doing It Right diving involves a series of choices about how to optimize your gear selection to maximize your dive quality. The system can be as subtle as making sure that your manifold has a soft rubber knob to resist cracking or deforming in the event of a brush with an overhead object, or as obvious as making sure that your stage bottles are properly marked with their maximum operating depth.
