Designed by a collaboration of experts, the O2ptima combines the benefits of the Micropore cartridge-based CO2 scrubber that now also accepts granular absorbent, Dive Rite's XT series first stage regulators, SiTech exhaust and manual addition valves, and now offers the Shearwater Research closed circuit mixed gas controller and decompression computer. The O2ptima includes an ultra high performance DSV that now also includes bayonet hose mounts, low profile 2.5L over-the-shoulder counter lungs (3L or backmounted versions are available as an option), and recently updated to incorporate the Shearwater electronics package incorporating CAN bus technology supporting a robust four oxygen sensor configuration. For buoyancy control, the O2ptima includes the divers choice of the Dive Rite TransPac or TransPlate harness along with their CCR wing specifically designed for rebreathers. The O2ptima includes { 20 cuft | 3L } cylinders and modular valves, but also accepts a very wide range of cylinder sizes from aluminum 13's (2L) to steel 27's (4L). Less the cylinders, the entire unit can be carry-on luggage for most airlines.

We are an Authorized Dealer for the O2ptima eCCR. We offer on-line ordering along with a complete stocking inventory of accessories, spares and consumables. Dive Gear Express also offers O2ptima instruction at our facility in SE Florida.

The O2ptima is an adjustable { 22 to 25 in | 55.9 to 63.5 cm } high, { 13 in | 33 cm } wide, and { 8 in | 20.3 cm } deep and the weight (without cylinders and absorbent) is less than { 28 lb | 12.7 kg }. Although airline luggage restrictions vary widely, the O2ptima qualifies as "carry-on" with many airlines. A fully configured O2ptima, utilizing TransPac Harness and CCR Wing, with cylinders and the absorbent cartridge has a pre-dive weight of approximately { 51 lb | 23.1 kg }; compared to a single aluminum 80 open circuit rig of { 42 lb | 19.1 kg } or a double aluminum 80 open-circuit rig of { 87 lb | 39.5 kg }.

Shearwater Petrel Electronics Package

The Petrel electronics package from Shearwater Research provides both a solenoid controller and handset, along with an electrically isolated and independently powered PO2 heads-up-display. The Petrel is completely OEM integrated with the O2ptima-SR rebreather and provides full real time decompression dive computer capabilities, including required stop obligations and time-to-surface calculation. Features of the Petrel CCR dive computer and solenoid controller include:

  • Full Setpoint Control
  • Loop PO2 Monitoring w/CNS Tracking
  • Air, Nitrox, Trimix and Heliox gas support
  • User Defined Gradient Factors Conservatism
  • Easy to Read and Simple to Use
  • Adaptive Menus with Large Display
  • Automatic Setpoint Switching
  • Fast 2 Button Push OC Bailout
  • Ascent Rate Display
  • Battery Voltage Display w/Battery Low Warning
  • Metric (Meters) and Imperial (Feet) Units
  • High resolution QVGA, full color LCD display

Handset - The handset display, normally worn on the wrist, shows the measured PO2 for three oxygen sensors, dive time, actual and max depth, and decompression information. Decompression information includes required stop obligations and time-to-surface calculation.

Heads-Up-Display (HUD) - There are two options for the HUD. The LED HUD option allows you to monitor your loop PO2 via the heads-up display using color LEDs mounted on the DSV. The actual loop PO2 for each of three sensors is displayed via a flashing code. The NERD HUD option provides a special optics and O2ptima specific mounting system that projects the equivalent of the Shearwater Petrel as a heads up display directly in the eye of the diver.

Four Oxygen Sensors - The head contains a total of four oxygen sensors, numbered 1, 2, 3C and 3H. The handset and HUD each share sensors #1 and #2, but the handset and HUD use sensors #3C and #3H independently of each other. You can also order an optional factory installed external PO2 monitoring cable with Fischer 103 connector to transmit readings from sensors 1, 2 and 3H to an independent backup Shearwater Petrel-EXT dive computer.

Bühlmann ZH-L16 Deco Algorithm with Gradient Factors - Bühlmann-based algorithms are among the most widely used decompression models, and the ZH-L16 algorithm is programmed into   many of today's dive computers. The improvement of Gradient Factors allows the diver unique and individual control of their dive computer decompression calculations.

Full Nitrox/Trimix/Heliox Support - The dive computer supports any breathing mixture of Nitrogen, Oxygen, and Helium. As many as ten different gas mixes (5 open circuit and 5 closed circuit) can be pre-defined by the diver and selected at any time during a dive. The O2ptima includes full Trimix support as a standard feature.

Rebreather Training

Every rebreather requires formal, model specific, training in order to competently dive with the equipment. Rebreather equipment pricing does not include training, and training is solely the responsibility of the purchaser. Training is available worldwide and Dive Gear Express also offers instruction at our facility in SE Florida for all models we sell. The typical full course training time is five to seven days consisting of a classroom lecture, confined water session and at least six OW dives. Our recommendation to divers seeking rebreather training is to select an instructor having several hundred hours of rebreather dives and for whom rebreathers are their primary mode of diving.

Because diving is a voluntary recreational activity, prior to delivery and training you must complete and sign legally binding agreements known as a Release of Liability and an Express Assumption of Risk. If you are not already certified for the rebreather, per manufacturer requirements you will receive a disabled unit that can only be enabled by your instructor. Once you complete training, your instructor will permanently enable your unit.

For general information on rebreathers, transitioning to closed circuit diving, rebreather safety, course descriptions, prices, and logistics, plus an equipment list for rebreather training, please visit CCR Instruction for the Dive Rite O2ptima and Poseidon Se7en rebreathers page.
