With over 60 years of diving experience and having sold almost every Full Face Mask (FFM) on the market, it was easy to see there was a need for something better. A common problem with most FFM is the seal. The lack of a good seal causes the diver to use air quicker and can interfere with the diver's ability to hear if using underwater communications. With that in mind, the GFFM was designed around a double seal. This along with many other great features (i.e. semi positive pressure, quick release 2nd stage, easy maintenance, etc.) is why you will find the Guardian is the best choice for your money when looking for a full face mask.
The Double Seal 55-60 Shore A Liquid Silicone Skirt with High Strength Polycarbonate Visor (Lens) was specifically designed to allow people with a small faces or a slim face, especially in the temple area, to seal better. Everyone has a little different face. As divers you all know how important being able to equalize is. Equalizing is a challenge for all full face masks One-Size does not fit all! In order to ensure everyone can equalize, OTS has put together an Equalizing Kit which comes with every Guardian full face mask. The kit consists of two bases. One is a standard size without any holes. It can be adjusted up or down to fit as necessary. The other base has two holes which allow for different size pads that can be added. In the event the standard base does not work for you, one of the pads and the other base should fit the bill.
The Guardian offers an easy to adjust buckle system. OTS has made the buckles out of a tough, robust compound which should give you years of use. However if a buckle does break, it will be easy to replace. There is definitely one thing you won't have to worry about and that is RUST. Rust is the number one cause of replacement when using metal buckles. The 5-Point Spider Strap is just the right thickness to allow for a comfortable fit no matter what depth you go to. As you go deeper, the strap will help take up the slack. When you go shallow and everything readjusts, so will the strap keeping you snug in your Guardian full face mask.
The ABV-1 Ambient Breathing Valve allows the user to breathe ambient air at the surface, conserving your tank air. It is simple to use and its low profile keeps it out of the way. To use the device, while on the surface simply rotate the valve counterclockwise. The one way valve will open and allow air into the FFM. The one way valve located on the inside of the FFM ensures that your exhaled air does not go back out the valve. Your exhaled air is sent out through the second stage regulator ensuring you do not get a Co2 "building" in the FFM. The valve also is forced closed when diving. The over pressure in the FFM assures that. If you forget to close the valve before diving, the valve disc will help keep water out.
The Guardian full face mask has a custom designed Balanced Downstream Demand Valve 2nd Stage Regulator that was specifically designed for a full face mask. OTS also realized what is involved with the maintenance of a full face mask and regulator. They designed the 2nd stage with trouble free maintenance in mind - it is easily removed! This is important for cleaning and/or maintaining your full face mask. The Regulator has an Injected-Molded High-Impact Housing for Strength and Durability and comes with a 32" (81.3 cm) 3/8" threaded Low Pressure Hose.
You paid hard earned money for your Full Face Mask. Why not keep it in a bag designed to store it like it is supposed to be stored. The mask bag was designed to help keep your mask in the right drying position, keeping water from pooling in your 2nd stage regulator. It also has vents to keep good ventilation helping to stop mildew and drain holes to let water drain away from the mask. Lots of storage pockets as well. One is a dry storage compartment! The bag has a carrying handle as well as a shoulder strap. In all, it's a great investment to help keep your valuable GFFM. The Guardian Full-Face Mask is available with a Black, Blue or Yellow Skirt with Black Frames or Black Skirt with Pink, Green, Blue or Red Frames, comes with a 12 month limited warranty and Owner's Manual.
