Happy Diving! Full Face Mask

What is about Full Face Mask?

A full face mask is a mask that covers the entire face. The full face mask used in scuba diving has a mask edge called a skirt that is in close contact with the forehead, temple, cheeks and jaw lines. The mask is firmly fixed to the head with 5 belts. The regulator (breathing apparatus) is incorporated in the full face mask, a small space that can breathe is completed inside the full face mask.


The history of the full face mask is old, it has been used for commercial diving which requires conversation in the water and the surface, also underwater report of the TV. Moreover, it is also used for submarine operations such as adding hood and other equipment, super-extreme cold seas and dams, and diving work in contaminated waters.


Diffusion to leisure diving is delayed.

The reason for being late is not clear, but people who buy the masks themselves and borrow the regulator (breathing apparatus) with rental or maybe because there are many people who have masks and snorkel by snorkeling or skin diving. As a technical aspect, it may be related to complication of dealing with air shortage in the water. As for the shortage of air, we will touch again in the "demerit" part of the second half of the article.


However, recently in the leisure diving industry many benefits of full face mask have been reconsidered, from PADI a full face mask training course was announced or purchased as personal equipment in leisure divers with weak jaws and tooth.  Some people mentioned impression that "It would have been better if we could receive a license course with this mask from the beginning" in the diver.

Disadvantage of Full Face Mask

You can not use this mask unless your face fits

If your face is too small like a child, your face may not fit with the full-face mask. In such cases you can not use full face mask.


※ In our Taiken scuba diving(experience diving), we will rent you with a regular mask and a separate regulator (breathing apparatus).

It's complicated when you have no air.

Fully fix the face and mask securely with a belt so that the full face mask does not come off the face. This raises the safety and comfort of the full face mask, but in the case of air exhaustion it is necessary to remove the entire mask from the face. This is more complicated than removing a regular regulator from the mouth. Therefore, when using a full face mask, it is very important to "save enough air" and "check and remaining amount of air frequently".


※ You don't have to worry about your air even you use full face mask or regular regurator, because it's the most important work to check air carefully for customers.

Advantage of Full Face Mask

Water doesn't enter the mask

Although it is premised that it is fitting, the full face mask is structured to be very hard to inundate. Also, it is made to drain easily even if there is flooding in the mask. Important thing is to wear it according to the procedure and to start diving after conducting the test according to the procedure with the feet standing depth.

You don't have to bite regulator mouthpiece

  • The regulator never goes out of your mouth
  • Your chin won't be tired
  • You can talk under the water
  • It's easy to clear your ear
  • You can breath from your nose (sometimes it's not best way to breath from nose, it's depend on mask fitting)

Hight safety

People who originally have injuries or a case history that are problematic in diving can not dive, but in the unlikely event that the regulator will not come out of the mouth in the event of loss of consciousness in the water.

Diving in cold climates and contaminated water can be done etc.

Full Face Mask for Taiken (experience) scuba diving Introduction

Loco Divers is a diving school since over 25 years ago, it'a head office of the Irabujima marine Marine Center. In addition to school , Loco Divers has been work using full face masks, such as survey in contaminated water and safety management of TV underwater reporters. In particular, the license  course using full face mask has changed our perception significantly.


In the license course, it includes acquisition of a skill called "mask clear" (a skill that drains the submerged mask water underwater), but practicing this skill with a full face mask is very difficult. Even if you create a gap on purpose by pulling the mask from the face for practice, water will hardly enter just because the air inside leaks out. Structurally it was very difficult to put water in the full face mask. In the end, what we did to achieve this skill was to "remove the mask completely and reattach". As expected the water entered. The full face mask was a mask in which "water does not readily enter even if you want to enter it".


Loco Divers has educated over 1,500 new divers. When asking what skills you most disliked to graduates, most divers say "mask clear". People do not like having their nose and mouth covered by the water.


These two things, "It is hard to get water even if you think to be in it ", "Everyone dislikes mask clear" became a hint for introducing a full face mask to Taiken (experience) scuba diving. After repeating the test by the instructor, this idea was introduced to the Saipan branch from the mid 2000's. The Irabu-marine Marine Center is taking over its know-how now.
