OMS ® BC / Back Plate Harness Systems
Back Plate / Harness Specification Sheet       Proper Stringing of Quick release buckle

Back plates: OMS's superior deburring process eliminates back plate sharp edges, and prevents abrasion and cuts to webbing and BC’s. The Aluminum Back plate weighs 1.75 lbs., the Stainless 5.75 lbs and both include the following slots: 1” and 2” width Crotch Strap, (2) Cam Band, and a bottom slot to accommodate band bolts that are slightly off 11” On Center. Stainless Steel plate is passivated to prevent oxidation and the Aluminum plate is Hard Coat Anodized.

Harness Systems: OMS ® now offers 5 innovative harness systems that can be coupled with the Aluminum or Stainless Steel back plates. Perhaps the newest and most innovative development is that the Comfort Harness Systems I™ and II™ along with the IQ Pack™ now incorporate a pull dump tunnel on each shoulder pad. See figures 6 and 7

OMS ® PROFILE™ SIDE-MOUNT SYSTEM       Side-Mount System Setup

This system has filled a void and will offer the “at home” and traveling diver freedom from the weight concerns of handling “back mounted” doubles. Side-mount allows individuals with limited physical abilities and lower back issues to enjoy the redundancy of two tanks and two regulators by minimizing the amount of weight on the lower back and lowering the center of gravity for increased stability when entering/exiting the water. Additionally reaching behind your head to shut off or turn on your manifold valve is a thing of the past as both cylinder valves are near your hands. Traveling divers can relax knowing that easily available single tanks are all they need to enjoy redundancy and adequacy of gas supply for any dive around the world.

BP-SMS
    Features:
  • Allows the diver to utilize most harness and wing systems (with standardized 11 inch O.C. hole spacing)
  • Over the shoulder design keeps the wing close to the divers back and allows air to travel freely from divers left to right
  • Integral bib adds over 1/8” inch of abrasion protection to the vulnerable top part of the wing
  • No changes to the fit of the harness throughout the inflation of the wing from empty to full capacity
  • Permits the Rebreather diver to back mount the CCR scrubber and side mount the Oxygen and Diluent cylinders
  • Enables the diver to back mount the bottom gas and side mount the decompression gases
  • Streamlines the diver allowing access to tight, remote, hard to reach caves and wreck passage ways
