Mask Care and Maintenance
Care Before the Dive:
- During the manufacturing process, a thin film of silicone will develop on the glass lens. This film of silicone will cause rapid fogging that is resistant to conventional anti-fog measures. It is important to remove this film of silicone from the lens prior to your first dive. To remove the film you will need to scrub the lens inside and out with a mild abrasive. Gear Aid Sea Buff Dive Mask Cleaner is ideal. Rub the cleanser into the lens with your fingers several times and then rinse clean thoroughly.
- Mask fogging is a normal occurrence, even after the film of silicone has been removed. Normal fogging can be easily prevented with aftermarket anti-fog agents or saliva (we prefer Gear Aid Sea Drops). Rub onto the lens and then rinse. Your dive can now be fog free!
Before use, always inspect every part of the mask (including the buckles and strap) for damage, defects or irregularities. If any issues are found, do not use the mask until the issues are corrected or the mask is replaced.
Care During the Dive:
- When entering the water either from a boat or a beach, place a hand over the lens of your dive mask and hold it securely in place. This will help ensure your mask stays in place during entry and will help deflect any direct impact of water on the lens caused by the jump into the water or any approaching waves.
- A typical dive staging area is a dangerous place for dive masks. Care should be taken to not leave your mask in a location where it might be exposed to dropping weight belts, tanks or stepped on accidentaly.
- It is best to avoid putting your mask on your forehead at any time during the dive. Several factors can cause the mask on your forehead to be dislodged and subsequently lost. If you want to temporarily remove the mask from your face, the most secure option is to place the mask around your neck.
Care After the Dive:
- Soak in warm fresh water (not over 120°F /49°C) to dissolve any salt or other mineral deposits.
- Rinse thoroughly with fresh water and towel dry before storage.
- Store in a cool and dry place out of direct sunlight.
- Store in provided protective box to avoid permanent deformation.
Repairing a Damaged Mask:
Damaged parts must immediately be replaced using original spare parts. Please contact SubGravity for guidance and availability of replacement parts.
Using the Mask / Adjustment
- When putting on the mask, brush away any hair caught between the silicone skirt and face. Hair trapped under the skirt is the most frequent cause of water leakage.
- To tighten the strap, simply pull back (away from the lens) on bothstraps evenly, until the strap is just tight enough to hold the mask on your face. Do no overtighten straps!
- To loosen straps, push on the small, round symbol in the center of the buckle, this will release the tension on the strap.
PREVENT MASK SQUEEZING: Pressure increases when descending into water. Just after you equalize or “clear” your ears, you should also equalize your mask to avoid “mask squeeze”. If you use the Valsalva maneuver to clear your ears (pinching your nose and blowing gently) then follow this process by gently pulling the nose-pocket away from but not off of your face, as you slowly add air to the mask through your nose.
Do not dive head first with any diving mask into water.
Avoid any contact with alcohol, oil, gasoline, aerosols, or chemical solvents. Do not expose any part to aerosol spray, as some aerosol propellants attack or degrade rubber and plastic materials. Do not use any type of alcohol, solvent or petroleum based substances to clean or lubricate any part. Do not store your equipment near any oil, gasoline, chemicals, or solvents.
Never use this mask as a substitute for appropriate above-water safety eyewear. The Vadose TRU CLEAR lens exceeds the impact test requirements set by the American National Standard Institute, Z86.11-1985 and well as the European standard EN 16805:2015. Impact resistant lenses can break or shatter and cause injury to the user if subjected to undue force or impact.
