Mask features
The Apollo SV-4 Panoramic Mask uses four windows to open up the view to the sides. A double-flanged silicone skirt and swivelling buckle attachments provide fitting adjustment for recreational diving and snorkelling.
- Four-window layout adds side visibility to the front viewing area.
- Double-flanged silicone skirt provides flexible contact around the face.
- Push-button buckles allow straightforward strap adjustment.
- Flexible swivelling buckle attachments move with the strap.
- Protective plastic box is included.
Snorkel features
- Semi-dry splash guard: The shaped top helps deflect spray and splashes. It stays open rather than sealing with a float valve.
- Oval tube and silicone flex section: The streamlined upper tube joins a flexible lower section, allowing the mouthpiece to move without pulling the entire snorkel.
- Large collection chamber: Water gathers below the mouthpiece and can be cleared through the one-way purge valve.
- Replaceable angled mouthpiece: The orthodontic-style silicone bite can be replaced when worn, extending the useful life of the snorkel.
- One-handed quick release: The detachable keeper lets you separate the snorkel from your mask without rethreading the strap.

The regular-to-large fitting guide is a starting point only. Check the seal, cheek clearance and nose-pocket comfort before selecting the mask.
Face width, shape and nose-pocket comfort determine mask fit. A small, medium, large or youth label is a starting guide only. Keep hair clear of the skirt and use light strap tension; do not overtighten a mask to compensate for a poor fit.
Snorkel fit and use
Adjust the keeper so the mouthpiece rests comfortably without tension in the lower tube. Despite “Dry” in the model name, this snorkel uses a semi-dry splash guard: the top can admit water when submerged.
Use the snorkel for breathing at the surface with its opening above the water. Clear any water before taking your next breath; a snorkel does not supply air while submerged.
Buying for someone else
If this is a gift, ask about the wearer’s current mask fit and allow time to check the seal and mouthpiece comfort before the first trip. Mask size and mouthpiece comfort need separate checks. Our Hallam team can help compare suitable shapes.
Care and storage
Compatible cleaning products
For standard uncoated mask glass, TUSA TEC52 anti-fog treatment is an option when permitted by the mask and treatment instructions. For a separate neoprene strap cover, if you use one, we recommend Cressi Neoclean Wetsuit Wash or Revivex Wetsuit Shampoo to clean compatible neoprene. Wash that component separately according to its care label and the cleaner’s dilution instructions, then rinse thoroughly and dry in the shade. These neoprene cleaners are not a recommendation for the mask lens or a regulator assembly.
Rinse in fresh water after use, including the buckles, then let the mask dry in the shade.Store it in a protective case without crushing the skirt. Follow the supplied instructions for lens preparation and anti-fog treatment, especially for coated lenses. Avoid abrasive cleaners, toothpaste and flame treatment.
Flush the snorkel, mouthpiece and any valves with fresh water after use. Remove trapped sand and let the equipment dry in the shade before storage.
