Contact Simple Dive if you would like us to check your computer model before ordering.
How Wireless Air Integration Works
The transmitter installs into a high-pressure port on your regulator first stage and measures cylinder pressure. It then sends that pressure information wirelessly to the paired dive computer.
Depending on the capabilities and settings of your computer, this information may be used to display:
- Current cylinder pressure
- Gas time remaining
- Gas consumption information
- Pressure-related warnings or alarms
- Multiple-cylinder pressure information on supported computers
The transmitter supplies pressure data. Features such as gas-time calculations, alarms and multi-transmitter displays are functions of the paired dive computer.

Important Oxygen & Diver Training Notice
The 100% O₂ compatibility of this transmitter is an equipment specification. It does not mean that an untrained diver should use oxygen-rich breathing gases.
Divers should not use breathing gases containing more than 21% oxygen unless they have received appropriate training and certification for the gas mixture and its intended application.
Recreational Nitrox training generally covers enriched-air mixtures only within the limits of the diver's certification. High-oxygen mixtures used for accelerated decompression, stage diving or technical diving require the appropriate additional training.
Always follow the oxygen exposure limits, maximum operating depth, oxygen partial-pressure limits and procedures taught by your recognised diver-training organisation.
Simple Dive offers Nitrox Diver training for divers progressing beyond air.
Divers progressing into accelerated decompression and higher-oxygen decompression gases can also view our TDI Advanced Nitrox & Decompression Procedures course .
Important Equipment Compatibility for Oxygen-Rich Gas
An O₂-compatible transmitter is only one part of a complete breathing-gas system.
When elevated oxygen concentrations are used, all relevant gas-contact components must be appropriate for the intended oxygen concentration. Depending on the configuration, this may include:
- Cylinder
- Cylinder valve
- Regulator first stage
- High-pressure fittings
- Hoses and pressure components
- O-rings and compatible materials
Installing an O₂-clean transmitter does not convert an otherwise unsuitable regulator or cylinder system into an oxygen-compatible system.
Transmitter Installation
The transmitter connects to a standard 7/16" UNF high-pressure port on a compatible regulator first stage.
Ensure the transmitter is installed in accordance with the manufacturer's instructions. Do not install it into a medium-pressure / low-pressure regulator port.
For technical or oxygen-rich configurations, the complete regulator and gas system should be set up and maintained appropriately for the gas being used.
Using a Transmitter With an SPG
Wireless air integration provides convenient wrist-mounted cylinder-pressure information and can help create a streamlined regulator configuration.
Whether a separate analogue submersible pressure gauge (SPG) is carried as a backup depends on the diver's equipment configuration, training, procedures and intended dive. Technical divers should follow the redundancy requirements and procedures appropriate to their training.

Frequently Asked Questions
Is this the 40% or 100% O₂ Aqua Lung transmitter?
This listing is for the O₂-clean version suitable for breathing gases containing up to 100% oxygen. This version is identifiable by its green battery cover.
Can I use this transmitter with normal breathing air?
Yes. The 100% O₂ rating represents the transmitter's maximum oxygen compatibility. It can also be used with normal breathing air and appropriate Nitrox mixtures.
Can I use 100% oxygen because the transmitter supports it?
No. Equipment capability and diver qualification are separate issues. Oxygen-rich gases should only be used by divers who are appropriately trained and certified for the gas mixture and its intended use.
Does a recreational Nitrox certification allow me to dive with 100% oxygen?
Not automatically. Recreational Nitrox qualifications apply only within the oxygen concentration, oxygen exposure and operational limits of that certification. Higher-oxygen gases used for decompression require appropriate technical diving training.
Does the Aqua Lung transmitter work with Shearwater dive computers?
It is compatible with selected Shearwater air-integrated computers that support legacy MH8A/Pelagic transmitters. This transmitter is marked FCC ID: MH8A. Confirm your individual computer model before purchase.
Does it work with Oceanic dive computers?
It can work with selected Oceanic air-integrated computers using the corresponding Pelagic/MH8A transmitter system. Exact compatibility depends on the computer model.
What does FCC ID MH8A mean?
MH8A identifies the legacy Pelagic wireless pressure-transmitter system used by a number of air-integrated dive computers. It is particularly useful when checking cross-brand compatibility with compatible Shearwater and Oceanic computers.
Does the transmitter make my regulator oxygen compatible?
No. The transmitter is only one component of the breathing-gas system. Every component exposed to the gas must be appropriate for the intended oxygen concentration.
Can I replace the transmitter battery myself?
Yes. Aqua Lung specifies that the transmitter battery is user-changeable and commercially available. Follow the manufacturer's battery-change instructions carefully to protect the sealing surfaces and O-ring.
Does the transmitter display cylinder pressure by itself?
No. The transmitter measures cylinder pressure and sends the information wirelessly to a compatible air-integrated dive computer. The pressure is displayed on the computer.
Will it calculate my remaining gas time?
The transmitter supplies cylinder-pressure data. Gas-time-remaining calculations depend on the features and settings of the paired dive computer.
Do I still need an analogue SPG?
This depends on your equipment configuration, training and intended dive. Some divers use wireless air integration as their primary pressure display while others retain an analogue SPG as a backup. Follow the redundancy procedures appropriate to your training.
