How To Equalize With Full Face Snorkel Mask?

A full-face snorkel mask involves equalization, which involves exhaling gently through the nose while keeping the mouth closed. This action helps to regulate the pressure inside the mask and equalize the pressure in the ears. Equalizing is something that all divers have to do, thanks to Boyles Law. Depending on the style of mask used, the techniques to equalize differ. The OTS Guardian Full Face Mask utilizes an equalizing block or V Block to block off the diver’s nostrils to clear their ears.

During a dive, a large volume of air in the mask restricts access to the nose, making it difficult to equalize the pressure in the ears. Both masks have a piece of rubber underneath the nose inside the mask, which can be pushed up to block the nostrils and equalize. However, not everyone uses the block, and some people can equalize. Most full face snorkel masks have adjustable straps that allow for adjusting the mask to fit the face snugly. Silicon skirting on the masks also helps with comfort.

Equalizing in the Guardian Full Face Mask is simple, but since the distance of the chin to the nose varies, first adjust the equalizing block. A full-face mask does not allow equalization as you dive deeper, as divers typically block their noses and begin to exhale to get rid of the pressure.

How do divers equalize their ears with a full face mask?

VALSALVA MANEUVER | Pinch Your Nose and Blow. This is the method most divers learn: Pinch your nostrils (or close them against your mask skirt) and blow through your nose. The resulting overpressure in your throat usually forces air up your Eustachian tubes.

• It does not activate muscles which open the Eustachian tubes, so it may not work if the tubes are already locked by a pressure differential.
• It’s too easy to blow hard enough to damage something.
• Blowing against a blocked nose raises your internal fluid pressure, including the fluid pressure in your inner ear, which may rupture your “round windows.” So don’t blow too hard, and don’t maintain pressure for more than five seconds.

Swallowing—and various methods of equalizing—are all ways of opening the normally closed Eustachian tubes, reducing the pressure differential between the outer ear and inner ear. The safest clearing methods utilize the muscles of the throat to open the tubes. Unfortunately, the Valsalva maneuver that most divers are taught does not activate these muscles, but forces air from the throat into the Eustachian tubes.

Why are full face snorkels not allowed?

Can we use a full-face snorkeling mask? The answer is no, and this is why.. Full-face snorkeling masks have gained popularity in recent years due to their promise of enhanced comfort and ease of use. While some snorkelers may find full-face snorkeling masks convenient, they pose four significant risks. The first risk is full-face snorkeling masks can pose a high chance of carbon dioxide build-up within the mask due to the limited ventilation system. This can result in symptoms like dizziness, nausea, and in extreme cases, unconsciousness.

Another risk is the utilization of full-face snorkeling masks has been linked to an increased likelihood of engaging in shallow breathing patterns. The third risk is the design of these masks can make it difficult for users to clear water from the mask, leading to restricted visibility and potential panic underwater. Finally, if water seeps into a full-face snorkeling mask, the task of clearing it becomes more intricate compared to conventional masks.

In this blog, we will go into further detail discussing the four risks and shed light on why these masks are not suitable for snorkeling. To make the most of your snorkeling experience, the Maui Snorkeling morning and afternoon tours provide reliable traditional snorkeling masks suitable for individuals of all ages, eliminating the need to bring your own!

How to equalise in a full face snorkel mask?

One of the most commonly asked questions is “How do you equalize in the Guardian Full Face Mask?”. Equalizing in the Guardian Full Face Mask is simple. Since the distance of the chin to the nose is different for everyone, first you must adjust the equalizing assembly to custom fit you. We offer different size pads and wires to build up or lessen the size of the equalizing assembly. The equalizing block can also be moved higher or lower by fixing the assembly on higher or lower notches on the wire stand. Once you’ve achieved the equalizing assembly fits you in both comfort and function, you will then push up on the base of the regulator which will push the equalizing assembly up on your nose, blocking your nostrils, and allowing you to equalize.

Can you dive underwater with a full face mask?

Conclusion. A full-face snorkel won’t turn you into a dolphin but it can definitely make your snorkelling experience a much more enjoyable one! It’s important to remember that full face snorkel masks are the only suitable for diving one to two meters deep and always ensure to submerge vertically down to stop water from entering the breathing tube. Failure to follow these tips can be dangerous when using a full face snorkel mask. If you are looking to do more deep diving then we recommend checking out our traditional snorkel set. Perfect for free diving with equalisation nose pinch technology and free mouth nozzle breathing tube.

Can you equalize with a full face mask?

Stay On The Surface. Never dive underwater with full face snorkelling masks! Yes, you often see photos of people diving underwater with them. Worse, the companies that want to sell the masks use these type of pictures. But this is highly dangerous — they can be used on the surface only.

With most full face snorkelling masks you can’t equalise by blowing hard and long against pinched nostrils as you descend underwater. Thus you may rupture the round window membrane between your middle and inner ears.

The “mask squeeze” (pressure) is much greater than with a traditional dive mask — because of the greater surface area and interior volume. That pressure can contort the mask/face seal and allow water to breach the seal and flood the full face snorkelling mask. This is not something you’d want to deal with at depth, especially given it’s difficult to remove the mask, and you can’t easily clear it like you can a traditional mask.

Freedivers and spearfishers who apnea dive underwater on one breath prefer very low volume, close-to-the-eyes masks. Many recreational scuba divers also prefer low volume masks, as do most deep technical and cave divers. A full face snorkel mask is an extremely high volume mask, not suitable for use underwater. Experienced one breath apnea divers also prefer a simple, wide, short, open-end snorkel with no bells and whistles of any kind. A hole at one end and a mouthpiece at the other end. Suck, blow, keep it simple! Full face snorkel masks have a very complicated snorkel arrangement.

How long can you breathe underwater with a full face snorkel mask?

Conclusion. How long you can snorkel underwater with a full face snorkel mask depends on a number of factors, the quality and fit of your face mask, the weather conditions, currents & swell, your snorkelling experience, how comfortable you are in the water and your overall fitness level. 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. Remember, snorkels are designed to be used floating above the water, with only limited time to be spent actually underwater.

How to breathe with a full face snorkel mask?

As a full face snorkel covers your entire face, users are completely safe to breathe through their nose and mouth, providing a natural breathing pattern! This design is far more relaxing and comfortable compared to traditional snorkel masks. People who have high levels of anxiety often struggle with rhythmic breathing and avoid snorkelling all togethe, children snorkeling can also struggle with this! With a full face snorkel, these same people can calmly explore the beauty of the underwater world for hours on end. Another major difference between traditional and new full-face snorkels is the lack of tube pieces. Reef Mask full-face snorkels have an inbuilt air tube at the top of the mask, while traditional snorkels require the user to clamp or bite down on a rubber tube in order to breathe. This smart design eliminates jaw fatigue and allows people to actually smile for any underwater photos, truly a world first! A bonus feature is the full face snorkel mask tube can lockdown, making it super easy for storage.

Can You Choke on Sea Water With a Full Face Snorkel?

Reef Mask Full Face Snorkel is designed to clog and black ocean water from entering down the tube and into the mask. This is achieved through two ways: an anti-leak seal that is found around the lens of the mask, stopping water from seeping in like old traditional snorkel masks. The second feature is a water lock built into the tube, which stops any water from entering if the breathing tube begins to submerge into the water. This simple but effective mechanism has eradicated the need to blow the water out of the breathing tube when you submerge underwater and come back up, a feature that is not found with the traditional snorkel mask.

Why are full face snorkel masks not allowed in Hawaii?

Abstract. A recent rise in snorkeling-related deaths in Hawaii has inspired several bans on full face snorkel masks (FFSMs). However, while there are theories to explain the deaths, little physiological data exists about the way the FFSMs provide gas to an exercising subject. To evaluate the safety of the FFSM concept, this study was designed to test how use of a full face snorkel mask (FFSM) may be physiologically different than use of a conventional snorkel, and to assess if any of those differences could lead to increased risk for the snorkeler. Ten volunteer human subjects were tested using a variety of commercially available FFSMs, with real-time monitoring of blood oxygen saturation (SpO2), inspired airway pressure, and inspired and expired levels of carbon dioxide and oxygen. Two of the three FFSM design types were shown not to function as advertised, but none of the masks provided physiologically problematic gas supplies to the snorkelers. While this testing yielded no conclusive “smoking gun” to explain the snorkeler deaths, some of the mask models showed patterns of increasing breathing resistance with water intrusion because of a shared design characteristic, and this increased resistance could potentially create elevated levels of respiratory distress to snorkelers during real-world use.

Are full-face masks safe for snorkeling?

3. No Guarantee – As with all snorkeling equipment, there is no guarantee of safety. All equipment, especially full face snorkeling masks must be properly cleaned and maintained. Poor maintenance could prove to heave deadly consequences.

4. Fogging – If your mask is fogging up, it’s important to stop using it and get it re-fitted or try a different size as soon as possible. The breathing part should fit neatly over your nose and as close to your face as possible. When in use, only the breathing part should fog up while the looking glass should stay clear.

5. Tighter Fitting – The tighter fitting head straps of full face snorkeling masks make them harder to pull off in an emergency.

Snorkel Mart Full Face Mask – How Are They Safe?. The game-changer in full face snorkel masks is the revolutionary purge valve system by Deep Blue Gear.

Two years after the original full face mask hit the market, Deep Blue Gear developed a full face mask with additional one-way purge valves near the temples of the mask frame.

This new design allows exhaled air to travel half of the distance to escape the mask compared to the original design while the top of the mask is completely dedicated to inhaling fresh air.

Deep Blue Gear Is Tested. To make sure these masks’ extra purge valves work as they intended, all Deep Blue Gear full face snorkeling masks have been tested at an independent US-based testing facility called Dive Lab in Florida.

The results of these tests confirm that our masks exceed the EN 250 safety standard, which is widely used in the scuba diving industry to set the maximum safe concentration of CO2 in SCUBA regulators.

How Does it Work?. With a snorkel mask, you have separate areas for breathing in and out preventing you from breathing in your own air again.

The full face mask has a tube that is compartmentalized into three sections. Fresh air comes into the middle, carbon dioxide leaves through the top and water is dispelled out the bottom.

These valves keep oxygen steady and keep you safe and comfortable while providing a comfortable snorkeling experience.

Benefits of Full Face Masks. Full face masks were developed to make the snorkeling experience better. They are easier to use than traditional snorkels, and give a wider range of view.

There are many additional benefits of full face masks which make them so popular.

• Clear View – This is the biggest benefit of full face masks. Because the mask curves around your face, there is absolutely no obstruction to what you can see in the water. Your vision is not limited and your peripheral vision is not cut off. They don’t fog up like traditional face masks can, giving you the ultimate underwater viewing experience.
• Water Purging – The bottom valve, near the chin, is designed to automatically push any water to the bottom of the mask. This gives an easy way to remove water that may sneak into your mask by simply opening this valve.
• Easy Breathing – With a full face mask, you can breathe through your nose. For many snorkelers, this benefit changes the entire snorkeling experience. It makes breathing less of a focused effort because you won’t need to change your natural breathing through your nose.
• Minimal Effort – A full face mask requires very little effort to use. You don’t need to have a mouthpiece in your mouth, no biting or jaw strain, no mouth breathing and no need to strain your neck by constantly turning to see everything around you. It’s simply easy and comfortable for unlimited snorkeling.

When Shouldn’t You Use a Mask and Snorkel?. Breathing through a snorkel is only appropriate for relaxed surface swimming.

Anytime you are exerting yourself, you shouldn’t be using any type of mask.

If you are swimming hard for exercise, or find yourself paddling hard against a current, take the mask off and breathe air directly by lifting your face out of the water.

FAQ About Full Face Masks. What should I do if my full face snorkel mask fogs?. Typically, fogging only occurs in cold water. You can treat your mask with a defog solution or wash with baby shampoo. If you find that your mask is fogging in warm water, it is likely due to sweat, dirt, and sunscreen on the inside of the mask. Wash the mask thoroughly with a mild soap such as dish soap and a soft cloth to prevent fog.

Will a mustache be a problem while using a full face mask?. A mustache is not a problem with full face masks as long as the seal sits on the jawline and chin. However, beards and goatees can cause leaking.

Can I go free-diving with a full face mask?. No. Diving down deep with a full face mask is not recommended. A quick dive to a shallow depth may be possible, but a deep free-dive causes more pressure that is difficult to equalize in a full face mask, causing injuries to your ears and sinuses.

Are You Ready For a Full Face Snorkeling Mask?. Clearly, there is no question that full face snorkel masks have some advantages over a regular mask.

To ensure you’re using a safe, certified face mask snorkel, ensure you’re using a mask that has been tested and certified.
