Full Face Mask Course
This course is designed to introduce divers in the correct use of a “Full Face Mask” (FFM) unit.
A Full Face Masks have many applications, for example; diving in cold or polluted water and dives where normal verbal communications needs to be maintained. Another plus for using a FFM is that it creates less stress on the diver as breathing through the mouth and nose is more natural compared with tradition regulators.
A Full Face Mask is different than the traditional dive mask in that, the FFM encloses the mouth and nose which means that you can breathe through either. The demand valve is fitted to an oral / nasal mask instead of the traditional mouthpiece that is fitted to a normal regulator. This internal oral/nasal enables the diver to breath normally as if they were on the surface. For (FFM’s) that has a built-in communication system, will allow you to talk normally between you and your buddy or the surface supports /dive boat.
This underwater communication is extremely useful when the divers are conducting various underwater projects or tasks; such as, conducting underwater surveys, diving in low visibility, marine conservation surveys wreck diving etc. However, the FFM unit can also be used for normal recreational diving too.
>> Entry level requirement:
The entry level for this course is Ocean Diver or equivalent
>> Course Duration:
The course duration is 1-day
>> Theory lesson:
This short theory lesson starts by taking a look at the advantages of using a Full Face Mask. We also look at some precautions to consider when using this type of equipment. We then move on to take a look at the different components and features of the Full Face Mask which includes, the Mask, the Regulator, Nose blocks - used for equalizing your ears and the Spider etc.
The correct way to don the mask is very important if you want to avoid any sealing problems. The Full Face Mask has a number of straps (The Spider) that needs to be tightened and adjusted in the correct order if leaks or a malfunction of the mask is to be avoided. So at this point, we take a look of how to fit and adjust the mask properly.
The theory lesson concludes with some useful hints and tips when using a Full Face Mask.
>> Dry Practical:
On this Dry practical, you will practices the procedures of the correct fitting and removal of the mask. Once you have fully mastered this important skill, you can then progress the skill in a swim pool or shallow confined water.
>> Pool Lessons:
In this pool session, you will be able to become comfortable with the mask and its operations. As mentioned in the Dry Practical session you will run through a number of mask skills. The first skill you will learn is how to clear a flooded Full Face Mask, by using the regulators purge button.
After mastering this skill, you will then move on to the procedures of mask and regulator switching. As the Full Face Mask regulator is your primary air supply and is part of the mask, in the case of a total malfunction of the FFM you will need to bail-out and switch to a normal regulator and a traditional dive mask.
>> Open water dive maximum depth 6 – 10 metres:
On this dive you will gain experience using the FFM in a more realistic environment. On this dive, apart from becoming familiar with the mask and communication system, you will also get the chance to repeat the Mask Clearing and Mask and Regulator and Mask switching skills already learnt.
On successful completion of this course you will receive the BSAC Full Face Mask certification card.
