Full-Face Dive Mask FAQ

What is a Full-Face Dive Mask?

“Full face masks essentially fuse your mask and regulator (second stage) into one piece of equipment. So, your mouth does not have a regulator in it and, for better or worse, you can now, hypothetically, speak to your dive buddies!”

Do You Need One?

Benefits:

  • Communication with dive buddies and surface boat
  • Integrated regulator less likely to be lost
  • Larger field of vision than traditional masks
  • Reduced fogging due to consistent air circulation
  • Face isolation in cold water/muck diving prevents numbness

Drawbacks:

  • If lost, difficult to clear and replace (multiple straps)
  • Heavier and bulkier for travel
  • Requires specialized PADI certification training
  • More complex emergency procedures

How to Equalize Without Pinching Your Nose?

Each full-face mask includes integrated, adjustable nose pieces. To equalize, push the top of the mask to seal the nose pieces, then perform standard equalization.

Switching to Buddy’s Alternate Air

Signal out of air, remove mask using quick-release straps, accept buddy’s alternate regulator. Recommendation: Keep spare mask in BCD. Alternatively, some divers pair with buddies using compatible secondary hose attachments to their mask.

Prescription Lens Options

Ocean Reef offers optical lens supports that attach directly into masks, allowing opticians to install prescription lenses. Installation guide video

Lighting/Torch Add-Ons

Options include:

Requires extender/rail attachment systems on basic models

Communication Systems

Underwater and surface communication devices available as brand-specific add-on packages (microphone, receiver, wiring). Most intermediate+ models include dedicated comms ports.

Options:

Surface Air Valves (ABV)

Allow breathing ambient surface air to conserve tank gas. Most mid-level masks include ABVs; entry models offer them as purchasable add-ons for later installation.
