Is there a difference between a scuba mask and a snorkel mask?
Scuba masks have a lower internal air volume, making it easier for divers to equalize pressure at depth. Snorkel masks often have a higher internal air volume, which is fine for surface use but not recommended for deep diving. There’s been a lot of talk around full-face snorkel masks recently—and there have also been some questions. While the full-face mask works pretty well for snorkeling at the surface of the ocean for short periods of time, the dry-mouth snorkel is a far superior option for snorkeling in general.In most cases, we don’t recommend diving underwater for any more than 2 minutes with a full face snorkel. Even if you are an experienced snorkeler who is going out in perfect conditions, we don’t recommend diving for more than 2 minutes.Anyone that suffers from cardiac or respiratory issues have a higher risk when it comes to snorkelling and using a full face snorkel mask! If you or anyone in your family has a history of asthma, heart disease or any other serious medical issues then be cautious when snorkelling.While using a full-face mask you can inhale and exhale through either your nose or your mouth. The natural breathing helps keep you calmer and more relaxed in the water. There is also no learning curve or getting comfortable breathing through the snorkel, which is great for beginners.
What are the disadvantages of a full face snorkel mask?
The tighter fitting head straps of full face snorkelling masks make them harder to pull off in an emergency. That’s not good, and when combined with carbon dioxide build-up causing snorkellers to become dizzy or disoriented, it becomes a potentially lethal combination.

Both are comfortable, well made, and—most importantly—designed with proper airflow systems that make them safe to use.After trying a few different models, these are the two full-face snorkel masks I truly recommend: the Tribord Subea Easybreath by Decathelon and the Ocean Reef Aria.

They are a source of drag in the water, which is not a good thing when they tug on the mask, a decidedly critical piece of equipment. They can also be a source of entanglement, for example, with kelp or hair.
Why are full face snorkel masks not allowed?
Humans exhale carbon dioxide (CO2) when they breathe, and this CO2 can collect in the voids inside the mask when being used in the water. When CO2 levels increase in the mask, users may experience headaches, panic, dizziness, and unconsciousness, which of course can be life-threatening when experienced in the water! While full-face snorkeling masks may appear convenient, they pose significant risks, including: Inadequate Airflow: The design can restrict airflow, causing dangerous carbon dioxide buildup. This can lead to dizziness, confusion, and even loss of consciousness.In most cases, we don’t recommend diving underwater for any more than 2 minutes with a full face snorkel. Even if you are an experienced snorkeler who is going out in perfect conditions, we don’t recommend diving for more than 2 minutes.Navy SEALs can hold their breath underwater for two to three minutes or more. Breath-holding drills are typically used to condition a swimmer or diver and to build confidence when going through high-surf conditions at night, said Brandon Webb, a former Navy SEAL and best-selling author of the book “Among Heroes.
Is a black or clear snorkel mask better?
Some divers find black masks claustrophobic. This is why most beginners start with a clear silicone mask. They are also more “friendly” looking. Despite their advantages, full face snorkel masks have been banned in many locations. The primary concerns revolve around safety issues, including the risk of carbon dioxide buildup, limited emergency response options, and potential design flaws.CONs of a Full-Face Mask A full-face snorkeling mask restricts the access to your nose, so you are unable to equalize the pressure in your ears that increases as you dive down. What’s more, during the descent, a large volume of air in the mask creates a strong pressure on your face.There’s been a lot of talk around full-face snorkel masks recently—and there have also been some questions. While the full-face mask works pretty well for snorkeling at the surface of the ocean for short periods of time, the dry-mouth snorkel is a far superior option for snorkeling in general.While there is no statewide ban, some tour operators and snorkeling companies have chosen to prohibit the use of full face masks on their excursions due to safety concerns.
How do I know what size snorkel mask to buy?
You need to measure your face to find the right snorkel mask size. Measure the distance between your eyes, from the bridge of your nose to the outer edge of each eye. This measurement will help you find a mask that fits your face snugly and doesn’t let water in. The fit of the snorkeling mask is the most important factor to consider. A mask that doesn’t fit correctly can be uncomfortable and leak water, which can ruin your snorkeling experience. When choosing a mask, consider the shape of your face and the size of your head.To wrap it up, the main difference between snorkel masks and dive masks is that one is designed for going deep underwater while the other is mainly designed for the surface or shallow diving.A full face snorkel mask is not designed for breathing underwater – you cannot breathe underwater at all with this mask. It only allows you to breathe while floating on the surface, with the snorkel tube above water. When used correctly at the surface, you can breathe normally for hours, just as you would on land.Before shopping for a snorkel mask, measure your face to determine the correct size. You can use a soft tape measure to measure the distance between your eyes (width of your face) and the distance from the bridge of your nose to your chin (height of your face).
