The Spectrum Full Face Mask by OTS created the best Full Face Mask on the market that allows divers to user their own regulators and eliminating the heavy cost associated with standard FFMs, without sacrificing luxury. The Spectrum Full Face Mask provides a simple method to adapt your own regulator to the mask by eliminating the bite down mouthpiece and tying your own reg in with the rest of the FFM. This allows for some of the best features of our other Full Face Masks : no jaw fatigue, no dry mouth, double seal for a better fit, five point head harness and clear communications.

With over 60 years of diving experience, and having sold almost every type of Full Face Mask on the market, it was easy to see there was a need for something better. As a result OTS designed the Guardian Full Face Mask. A common problem with most FFM on the market today is the seal. The lack of a good seal causes the diver to use air quicker and can interfere with the divers ability to hear if using underwater communications. With that in mind, the GFFM was designed around a double seal allowing for the comfort of both small and large faces. Equalizing is a challenge for all full face masks one size does not fit all. In order to ensure everyone can equalize, we have 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 Guardians low profile allows superb visibility and its easily removable 2nd stage regulator works great for storage and easy maintenance. The 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. Adjustable head straps with robust hardware make this mask what it is, simply the best. We have also included a full face mask bag. 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. The bag has a carrying handle as well as a shoulder strap. The Guardian is fast becoming a standard with Search & Recovery, Law Enforcement, Commercial and Recreational divers alike.

With the Spectrum, Full Face Mask, Ocean Technology Systems created the best full face mask (FFM) on the market that allows divers to user their own regulators and eliminating the heavy cost associated with standard Full Face Masks (FFMs), without sacrificing luxury. The Spectrum FFM provides a simple method to adapt your own regulator to the mask by eliminating the bite down mouthpiece and tying your own regulator in with the rest of the FFM. This allows for some of the best features of OTS’s other Full Face Masks: no jaw fatigue, no dry mouth, double seal for a better fit, five-point head harness and clear communications. The all new Spectrum FFM has a coated tempered glass/iridium safety visor for exceptional and a wide field of vision. The skirt is manufactured from hypoallergenic silicone rubber with upper and lower visor clamps made from black polyphenylene sulfide (PPS) and the 5-point head harness made from EPDM a natural rubber blend. The inner frame, buckles and buckle locks are manufactured from glass filled zytel. OTS Spectrum FFM is tested to a maximum diving depth of 164′ (50 meters) per EN 250:2014. OTS Spectrum FFM is designed for water temperatures below 50° (10°C) and is suitable for cold-water diving applications. Ultimately, cold water performance is dictated by 2nd stage regulator being used. OTS Spectrum Full-Face Mask is tested for diving applications with breathing air per EN12021. OTS Spectrum Full-Face Mask has been tested per the Europea

Due to popular demand, OTS have developed a new high performance 2nd stage regulator. The Stealth (SRG-1) is designed to deliver more air at deeper depths! The venturi assist increases gas flow. This is a must when under a heavy work load or when you reach the deeper depths associated with Scuba diving. The diver cannot over breathe this regulator (assuming you have a high performance 1st stage). The new Stealth 2nd stage when tested at 200 fsw had a work of breathing (WOB) between 1.2 and 1.5 joules per liter. The venturi assist ensured the diver had minimal additional effort in his inhalation effort. The SRG-1 is a balance regulator employing a dynamic balancing chamber. This feature ensures the amount of air a diver draws remains low for different intermediate air pressures. In the event a first stage fails and starts producing air more than 200 PSI’s, the SRG-1 will free flow to prevent an unsafe build-up of pressure. The Stealth Full Face Mask can be set up for Through-water, Hard-wire or no Communications. The Stealth Full Face Mask comes standard with several equalizing pads to ensure you can custom fit the mask to your liking. The double seal of the Stealth Full Face Mask ensures a great and comfortable seal. THIS IS A MUST FOR THE HARD WORKING SEARCH & RESCUE DIVER! Miflex Supply Hose: The Miflex supply hose comes standard with our Stealth 2nd stage regulator. It is a high quality low pressure hose. The hose is designed with an external Nylon safety braiding which helps resist snags and abrasions. This double brading also resists UV rays when out of the water. This will extend the life of the hose. All the stainless steel fittings have been treated with a black PVD coating. The hose is a 32″ female 9/16″ UNF with a male 3/8″ UNF fitting. The hose includes 1 o-ring.
