Description

Details

The O2ptima is a fully closed circuit, constant PO2, electronically-driven rebreather with built-in decompression ability. Unique in the rebreather marketplace, the O2ptima is specifically designed for the rigors of cave diving where immediate surfacing is not possible. The resulting features are also highly desirable for wreck and deep ocean divers.

The O2ptima's design includes minimal risk of a caustic cocktail. Two water traps in the loop along with horizontal, behind-the-head positioning of the scrubber canister create a difficult path for water to travel. An even greater advantage is gained by using Micropore Extend Air scrubber cartridges, which do not contain dust. It is the dust that reacts quickly with water to form a caustic cocktail.

The O2ptima delivers excellent work-of-breathing that allows divers faced with strong flow or ripping current to breathe comfortably. Over-the-shoulder counterlungs along with the scrubber positioned behind the head means gas has less distance to travel, so the diver does not have to work as hard to "pull" gas through the loop. This also allows the O2ptima to have smaller diameter loop hoses, which minimizes jaw fatigue.

A stainless steel frame and Rhinotec 600-denier polyester cover protects the O2ptima from tight cave squeezes and rolling boats. Hoses, regulators and tanks are kept neatly streamlined and away from potential snags inside a wreck or cave.

The O2ptima comes standard with the following features (see tech specs for details):

  • Over-the-shoulder counterlungs
  • Shearwater Divecan - Petrel controller
  • Shearwater Divecan Heads Up Display (HUD)
  • Dive Surface Valve (DSV)
  • Automatic Diluent Valve (ADV)
  • Water traps
  • XT Regulators and hoses
  • AI R22 Oxygen Sensors
  • Choice of Dive Rite harness
  • CCR XT wing

Technical Specifications:

  • COUNTERLUNGS: Over-the-shoulder 2.5L counterlungs, 5 liter total loop volume provide easier work of breathing in all dive positions. Counterlungs include diluent and oxygen manual addition valves. An over pressurization drain valve is located on the exhalation counterlung. The O2ptima counterlungs are covered in tear-resistant Rhinotec. ( 6 liter set available on request)
  • ELECTRONICS: Powered by Shearwater Research, using the latest in Shearwater technology the DiveCan system. The oxygen injection has an independent control board and long lasting 9 volt battery with a detachable Petrel controller.
  • BACK UP ELECTRONICS: Powered by Shearwater Research, using the DiveCan Heads Up Display (HUD). This unit has its own control board and long lasting 1.5 volt power supply, all contained in its own seperate housing. The HUD has seperate LED's for each oxygen cell, color blind mode and red buddy warning light.
  • OXYGEN SENSOR MONITORING: The system utilizes 4 oxygen sensors, sensors 1 & 2 are shered by the Primary and Backup systems while the third cell on each are independent for maximum redundancy.
  • DSV: Dive surface valve utilizes a friction seal so there are no o-rings to wear out and replace on the barrel.
  • ADV: Automatic diluent valve adds diluent to loop automatically maintaining a breathable volume. Located on the inhalation counterlung, the ADV includes an in-line shutoff in case of free flow.
  • WATER TRAPS: Dual water traps, one in the canister and one in the T-piece on the exhalation counter lung minimizes possible water interaction with the scrubber cartridge.
