Page 5: Introduction
This full-face mask (FFM) is one of the few that has been designed from the ground up as a scuba diving mask. Years of experience has gone into the development and design of the Guardian and second stage regulator. It was designed with comfort, fit, and function in mind. Having... -
Page 6: Warnings And Precautions
Warning Note • Diving a Guardian full-face mask or any scuba diving equipment without proper training and experience can result in serious harm or death. • This is an advanced piece of diving equipment that requires special training and practice prior to diving it in an open water environment. -
Page 7: Description
Physiological Considerations The Guardian FFM protects the diver in other ways as well. If, for any reason, a diver were to become unconscious underwater, the Guardian FFM is able to maintain a breathable airspace in front of the diver’s nose and mouth assisting in survival (assuming the scuba tank has air). -
Page 8: Training And Practice For Safety
Training and Practice for Safety As with any piece of high-tech equipment, the Guardian FFM does require additional training and practice. Air sharing in an out-of-air situation is more difficult, often requiring bailing out of the mask (depending on your gear configuration). -
Page 9: Rear Aspect
Equalizing Insert Skirt (inner) Figure 2: Back of Mask Guardian Skirt The skirt of the Guardian FFM is made of high grade (55-60 Shore A) liquid silicone with some unique features that add to its durability, comfort, and functionality. Inside you will notice we have designed the mask with a double-seal (Figure 3). -
Page 10: Visor, Frame, And Ambient Breathing Valve
Visor, Frame, and Ambient Breathing Valve ® The Guardian FFM visor is constructed of high strength polycarbonate. Although scratch-resistant, it is not scratch-proof. Protect the mask when not diving by storing it in its bag. When diving, minor scratches on the outside of the visor are difficult, if not impossible, to see due to water filling the scratch. -
Page 11: Regulator To Mask Interface And Air Flow
Regulator to Mask Interface and Air Flow The Guardian Regulator is specifically designed for use with the Guardian FFM. The design allows inhaled air to flow in a directional manner through the mask. As the diver inhales, breathing air is injected through vents below the visor, flushing the mask with cool, dry air. -

It should be tight with no movement and will not dislodge. The Guardian Regulator is a balanced, downstream valve designed for excellent performance regardless of depth. The threads of the hose connector are SAE standard 9/16”... -
Page 13: Warning Note
Using two wrenches, attach the female end of the low-pressure hose to the second stage (Figure 7). OTS wrench (137053- 000) is supplied with the Guardian FFM; use this on the second stage and another wrench on the hose fitting. -

Utilizing these components will allow you to vary the height of the equalizing assembly. This feature gives the Guardian FFM an increased range of comfort and performance for virtually any size face. How does this work? The rubber, V-shaped equalizing block is designed to fit under your nose. -
Page 15: Preparation And Adjustment
ALWAYS inspect your diving equipment to ensure it is not damaged or defective and that it is fully functional. DO NOT dive the Guardian FFM or any other equipment if you have not verified that it is in good condition and working properly! If this equipment has been damaged, tampered with, or found to be defective, return it to OTS or have a qualified technician inspect it immediately. -
Page 16: Donning And Adjustment
Donning and Adjustment Proper donning is crucial when using any piece of diving equipment, even more so with the Guardian FFM. An improperly adjusted mask will result in jaw fatigue, increased air consumption, leaking, and an overall poor fit. Donning correctly starts with understanding how the mask fits. The mask comes in a single size designed to fit the widest range of facial dimensions possible. -
Page 17: Diving The Guardian
If the pad is too low, you will not be able to reach your nose to equalize. As previously shown, your Guardian mask comes with an equalizing assembly kit that will allow you to adjust the height of the pad. - Page 18 First, know the location of your air supply, then start by removing the Guardian FFM. This is best done by grasping the bottom of the mask and placing your thumbs on the lower buckle tabs. Pull out on these tabs, loosening and rotating the mask forward and back over your head.

Page 19: Warning Note
Next, take a cautious breath to ensure the mask has cleared and to prevent inspiring any residual water. After the first inhalation, look down and exhale forcefully to clear any remaining water. Repeat this forceful exhalation a few more times and you should have a fairly clear mask. Again, practice this until it is second nature. -
Page 20: Post-Dive Procedures
If necessary, a mild detergent may be used for cleaning the mask. Never use any harsh detergents, abrasives, or solvents on your Guardian FFM. Use caution when drying the visor after diving in a sandy environment to prevent any scratching of the lens. Do not use paper towels to dry or clean visor—they tend to scratch the lens. -
