1. How do you equalize in the Guardian Full-Face Mask?
Equalizing in the Guardian is simple. First you must adjust the equalizing assembly to fit you. We offer different size pads to build up the equalizing assembly to fit your nose. The equalizing block can also be moved higher or lower. 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.
2. What happens if my mask floods?
First off, due to the positive pressure inside the mask, it is very difficult to get water inside the mask. Even if you break the seal underwater, air will push water out instead of water coming in. Having said that, if you do manage to flood your mask, simply look up and press the purge button on your regulator. This will drain out the water. Resume normal position and take a hesitant breath to ensure all water is displaced. Repeat as necessary.
3. Can I use any 2nd Stage Regulator with my mask?
No. The only 2nd stage regulator that can be used with the Guardian is the OTS-designed regulator that is built into the mask.
4. I need glasses. Is there a kit for this?
Yes! Contact your OTS salesperson to find out how to install the eye wear accessory kit made for the Guardian. Your mask is already set up to use this!
5. What happens if my mask fogs? Do I still need defogger?
Due to the unique air system of Full-Face Masks you do not need any defogging agent. Your mask will not fog!
6. What happens if I forget to close my Ambient Breathing Valve®(ABV®)?
It’s always best to remember to close your ABV, however, if you forget to close it chances are you will be fine – no water will come in. That is, of course, as long as you remain at an upright position while underwater. If you leave your ABV open and invert upside down you can expect to flood your mask – and very quickly.
7. What’s the difference between Positive Pressure and Demand (Semi-Positive Pressure) regulators?
Why would I choose one over the other?
The Guardian Full-Face mask is a demand regulator with a semi-positive nature. Having said that, positive pressure is a feature of some full-face masks primarily used by SCBAs to continually deliver air to you whether you are demanding it or not. These are used for fire fighting and hazmat emergency response. Positive pressure is designed to keep contaminants out of the mask if there were a break in the seal by blowing air out. A demand regulator gives you air as you “demand” an inhale when properly sealed.
7B.) Is a demand regulator positive pressure on a full-face mask while underwater?
Yes. A demand regulator does maintain a slight positive pressure while in an upright orientation. This is due to the position of the regulator being lower than that of the rest of the mask.
8. What if I run out of air while diving a full-face mask? How do I buddy breathe?
If you are diving a full-face mask, it is highly recommended you are familiar with emergency procedures and are comfortable doing them underwater. Get in a pool and practice if need be. Read your manual!
It is highly recommended that you have a spare air supply octopus, pony bottle, etc. and a small spare mask on you. If you run out of air, remove your full-face mask, utilize your spare air and don your small mask. You cannot buddy breathe using a full-face mask.
9. Does the Guardian come in different sizes?
Nope. One size fits most. Because of the Guardian’s unique double seal, the mask will fit almost everyone. If the first seal doesn’t fit properly, we’ll get you on the second seal.
10. Does the silicon material of the skirt degrade or lose shape? Is it as durable as rubber?
The silicone material is sturdy as can be and does not warp or degrade. You can fully expect for your Guardian Full-Face Mask to maintain its durability and shape regardless of how often you use it.
11. I want to use my Guardian with a Hookah system. What must I do for this?
We do not recommend using the standard Guardian Regulator with a Hookah system. The air pressure required for the Guardian Regulator is 135 psi, which is a much higher requirement than most Hookahs. Although it can be done, you may not be able to enjoy the Guardian at its full potential. We recommend using the Guardian FFM w/ STEALTH Hookah Regulator. You can buy this as a set (Mask/Regulator) or you can buy the Regulator alone if you already own a Guardian FFM.
12. Why does the Guardian Visor have frosted sides? Can I get the visor without this?
Years of experience have taught us that without frosting the sides of the visor, many people experience vertigo, dizziness, or distorted views. Frosting the sides of the visor eliminates those problems and still allows for a great field of vision. Frosted visors are the only way they come.
