KEENE SPECTRUM FULL FACE DIVING MASK

KEENE SPECTRUM FULL FACE DIVING MASK (FM5SPECT) With the Spectrum Full Face Mask, Ocean Technology Systems 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. FAQ: How to install 2nd stage regulator into the Spectrum FFM? Remove the bite mouth piece (if installed) from the second stage regulator. Insert second stage regulator mouthpiece tube into the regulator port through the front of the Spectrum FFM. Install military standard (MS3367-7-0) zip tie tightly around second stage regulator so that it wraps around and fastens the mouthpiece tube securely to the Spectrum FFM. What are acceptable 2nd stage regulators? The regulator port of the Spectrum FFM allows regulators from 3/16" x 5/8" and sizes up to 1-7/16" x 13/16". Most standard 2nd stages should be compatible. How to equalize? Unlike the Guardian and Stealth FFM, the Spectrum FFM allows you to simply pinch your nose to equalize.
