Important Considerations When Purchasing a Freediving Mask
- It is often recommended to try on a mask in the store to see if it fits – that is, sticks to your face with an effective air-tight seal. This is a reasonable test but we have found that this is not indicative of the water tightness of a mask at depth.
- Often purchasing a mask is an experiment in trial and error to see if it fits your face and it does not leak.
- There is no correlation between the amount you pay for a mask, it’s brand and it’s water tightness. A cheap mask can be as effective as an expensive mask.
- Of course, as you descend the mask including the skirt pushes against your face. This is not replicated in a store when trying on a mask.
- In fact, it is important to have a comfortable fit with a mask at the surface. Do not try to have a tight fit in order to keep water out. This often reduces the effectiveness of the mask seal and causes “mask squeeze” as you descend.
- We believe the masks we sell will be effective in comfortably fitting more than 90% of faces.
- A beard or moustache can interefere with the seal of a mask. Some freedivers use petroleum jelly on their beard to increase the seal. We just think it is easier to shave.
- Most masks are touted as having some anti-fog resistance. This might be so when the mask is first purchased. Generally, any anti-fog properties do not last in a mask.
- If you want anti-fog properties in a mask use Johnson and Johnson Baby Shampoo Conditioner. It is Ph neutral, doesn’t sting the eyes (much) is very effective for about 1.5 to 2 hours in the water and is much cheaper than the dive store bought concoctions. You only need one drop on each lens. Best prepared well before diving so it drys and sticks to the lens.
- All new masks with glass lenses will need to be cleaned with a gentle abrasive substance such a toothpaste. Do not do this on polycarbonate or plastic lenses. You can buy dive specific concoctions for this task but toothpaste is just as effective for this simple, often one off task.
