READ THIS before buying a full face snorkel mask!
No matter how good the brand, there’s just no getting around some things with full face snorkel masks.
Whether it’s a traditional mask or a full face snorkel mask, water will get in if there’s any hair between the skirt of the mask and your face. Beards create tiny spaces that will cause water to enter the mask.
These are not designed for Free Diving or spear fishing. There’s too great a volume of air inside the face cavity of the mask, and it quickly becomes uncomfortable when diving below 10 feet (3 meters).
Full face snorkel masks are designed for snorkeling in relatively calm water. As with a traditional mask and mouthpiece, if you lean your head too far forward, water will enter the snorkel. The float valve system only works when the snorkel is in a vertical position. Water may enter the snorkel when duck diving.
Snorkel tubes on full face masks are not wide enough to provide a swimmer with enough oxygen when swimming at an exercise pace. These are not designed for swimming laps in a pool.
Full face snorkel masks are designed for leisurely surface snorkeling. They work wonderfully well when breathing calmly, but are not a good choice for swimmers while exercising. You will need to remove the mask when swimming longer distances to get to a new snorkel location. Heavy breathing/exercising is less effective in full face mask designs.
If you want something for swimming laps, or for more vigorous snorkeling, then have a look at the PowerBreather Snorkel rangeof snorkel masks. These are made for specially for swimming laps, or for swimming in choppy water.
