Suited for Malaysian Dive Sites

Care & Maintenance
- Rinse the metal frame thoroughly after each dive – salt accelerates corrosion over time.
- Dry completely before long-term storage; moisture trapped in the frame joint causes rust.
- Polish the frame occasionally with a soft cloth to maintain its finish.
- Inspect the seal between frame and glass – metal expansion in heat can loosen it.

The bio-metal frame sets this mask apart from standard plastic designs. The Apollo Bio Metal Duo Yellow is a premium tool for freedivers who want quality, durability, and performance in one package.

I used the Apollo Bio Metal Duo Yellow for my last dive trip at Pulau Tioman. Breathing was super smooth even at 30 metres, and I had no issues with jaw fatigue after an hour underwater. The bright yellow hose made it so much easier for my buddy to spot me in the low-viz water.

Thank you, Wei Ming, for sharing your dive experience with us. We’re happy to hear the regulator provided both smooth breathing and high visibility in those conditions. If you have any further feedback or questions about maintenance, feel free to reach out.

Is this regulator suitable for diving in cold water? I’m planning a trip to Sipadan and want to make sure the Apollo Bio Metal Duo Yellow won’t free-flow or freeze up during deeper dives.

Hi Navin, the Apollo Bio Metal Duo Yellow is designed and CE-certified to perform reliably in various environments, including cold water. Its dual-stage system helps prevent free-flow and is rigorously tested for use in challenging conditions, so it is well-suited for your Sipadan dives.

Love the comfort of the mouthpiece and the lightweight feel of the setup. Only thing is the purge button was a little stiff with gloves on my first few dives, but it’s getting easier with use.

Thank you for your feedback, Nurul Afiqah. We’re glad you found the mouthpiece comfortable and the regulator lightweight. The purge button typically loosens up with regular use, but if you experience any ongoing stiffness, please let us know and we’ll be happy to help.
