Military-Grade Breathing Systems


All users must be trained and competent in the use of this equipment

Failure to adhere to proper training and safety guidelines may result in injury or death.

The information below is not a replacement for professional training. Please reach out to your local dive shop to learn more about getting certified for scuba.

Preparing for use

Inspect the system

Visually check for damage prior to every use.

If your bottle has been opened for travel, ensure it is clean, empty, and dry.

Always check the green O ring and ensure it is seated correctly at the base of the threads before reinstalling the first stage regulator.

filling your tank

Check all your connection points

Always use a clean air source with oil/water filtration. Tightly secure all connections.

Filling your tank

Monitor your pressure

Do not exceed the Maximum working pressures:
  • 200 bar - ORCA 500
  • 300 bar - ORCA PRO (Carbon)
First time filling

Bleed valves

Warning: Do not attempt to disconnect the tank from the pump without first releasing the air from your pump's bleed valve!

Prepare for your dive

test your equipment

Prior to getting in the water, test everything on land.

be safe

Start shallow

Diving in the open ocean is extremely dangerous, only use the Orca as a primary air source in shallow water


Always exhale!

When ascending during a dive, it's crucial to exhale continuously to prevent overexpansion of the lungs, which can lead to a potentially life-threatening condition known as pulmonary barotrauma. This occurs when expanding air is trapped in the lungs due to inadequate exhalation during ascent, causing lung tissue damage. Proper buoyancy control and a slow, controlled ascent while exhaling is critical to prevent this condition, and ensure a safe and enjoyable dive.


Know your limits and be aware

The ORCA is not intended to be used as a primary source of oxygen at depths greater than 10 meters.

Always be aware of the air capacity in your tank by referring to the pressure gage at regular intervals

Nitrogen poisoning, also known as nitrogen narcosis or "rapture of the deep," is a condition that can affect scuba divers at depths below 30 meters (100 feet). It occurs due to the increased pressure at depth, which causes nitrogen to dissolve in the bloodstream. This can lead to symptoms similar to alcohol intoxication, such as impaired judgment, euphoria, and confusion. In severe cases, it can cause loss of consciousness or death.

To mitigate the risk of nitrogen poisoning, divers can use specialized gas mixtures, such as nitrox, which have a lower nitrogen content than regular air. Additionally, divers should adhere to safe diving practices, such as ascending slowly and avoiding deep dives beyond their training and experience level.

The Litres/Min (LPM) inhaled by a person varies greatly depending on their size, and circumstances. Typical Surface Air Consumption (SAC) rates from our product testing team were between 10-15 LPM.

A rough estimate of tank capacity can be calculated by multiplying the size (0.3L, 0.5L or 1.1L) by the number of megapascal of pressure the tank is at, then dividing it by the air consumption rate.

Examples are below:

10LPM on 1.1L ORCA PRO tank filled to 30.0Mpa =(300)(1.1)/10=

33 Min of breathing time

15LPM on 0.3L ORCA PRO tank filled to 30.0Mpa =(300)(0.3)/15=

6 Min of breathing time

12LPM on 0.5L ORCA alloy tank filled to 20.0Mpa = (200)(0.5)/12=

8.3 Min of breathing time

Approximately 30 minutes with a hand pump, 10 minutes with an electric pump, and < 2 minutes with the tank to tank adaptor.

30 day money back guaranteed. We send a postage paid box to you, No hassle.

2 year warranty on defects.
