NASA, NOAA, NPS, World Class Record holders, deep explorers and those who simply demand the best specify OMS® BC’s.       Why?

Pull down the zipper of the outer cover of the OMS® BC and you will see 1000 denier Nylon fabric backed with 5 to 6 oz. of Thermoplastic Polyurethane (TPU) and on the Chemically Resistant BC’s 5-6 oz. TPU front and back . This thicker TPU coating helps prevent abrasion and increases puncture resistance. Most competitors use only 1/2 oz. or no urethane backing on their BC covers making them susceptible to punctures, abrasion and subsequent leaks.

Housed inside the outer cover we use a puncture resistant bladder constructed from 200 denier Nylon fabric backed with .12 mm of TPU. Most of our competitors use only a thin plastic film bladder that is more susceptible to damage.

There are other differences such as 100% quality assurance inspection for leaks, imperfections and defects before your OMS® BC is delivered.

Elastomeric Retraction Band BC Features :

1. DUAL BLADDER: Inflator hoses and Dump valves are interchangeable for a variety of unique hose configurations. The dual bladder model features a total of four (4) pull dump valves located:

• Diver's Side bladder: lower left and top right
  
• Tank Side bladder: lower right and top left     (see figure at right)
  
• Colors: Black or Red

2. SINGLE BLADDER: The single bladder model has two (2) relief valves located: divers' right shoulder and divers' lower left.
   Inflator hoses and Dump valves are interchangeable
  Colors: Black or Red   (45 lb. & 60 lb. Black only)

3. POWER DEFLATION / ORAL INFLATION: The unique elastomeric bands (use is optional) assist in deflation, but still allow the diver to orally inflate the BC.

4. ELIMINATION OF AIR SHIFT: The OMS^® elastomeric bands evenly compress the BC, eliminating the massive airshift associated with non-banded BCs that typically occurs when changing body plane.

5. LOW DRAG / LOW SNAG: The OMS^® bands typically retract the BC to a width less than the diver's shoulders greatly reducing Drag and Snag potential.

6. TRIM ADJUSTABILITY: By adding or eliminating bands in different parts of the BC, the diver can adjust: a) lateral trim to compensate for stage bottles, cameras, etc. b) Horizontal trim e.g. head up, down or level.

7. Cam Band accommodation: (2) Top and (2) Bottom Slots are positioned in the non inflated area for Cam Band usage.

TESSERACT™ BC        

TRIM AND AIRFLOW: This BC is engineered with an 60 lb. lift dual bladder design, incorporates a “donut design”, resulting in superior buoyancy and trim control. The top of the BC (neck area) has a narrower air pathway design and the bottom air tunnel adds 10 lbs of lift (butt area) creating an optimum “heads up” trim position.

LARRY GREEN SIGNATURE SERIES BC™

The 45 lb. and 70 lb. Larry Green Signature Series™ BC’s incorporate the latest thinking in hydrodynamic engineering. Deep Underwater cave explorer Larry Green conceptualized this innovative design after many years of deep cave diving experience. Both the 45 lb. and 70 lb. lift BC’s are designed and tailored to fit the full length of the cylinders providing increased control over trim and the reduced width dramatically reduces drag. These are the first BC’s to be designed that are specifically tailored to fit aluminum 80 cu. ft and taller cylinders.
