Drain Tab
The Purge Drain Tab is located under the
chin pocket of the mask and is designed
to help fully eliminate any residual water
remaining after a flood and clear of the
mask. After clearing the majority of the
water out via the regulator purge button
simply pull down on the tab and blow out
any remaining water.
Visor Drain Holes
The Spectrum features two Visor Drain
Holes located in the inside of the mask
on the top of the oral nasal pocket where
the “teardrop” portion of the visor meet.
The holes are designed that if water pools
in the visor, it will drain into the oral nasal
pocket where it can then be evacuated by
blowing out the nose or mouth, or by using
the purge button of the 2nd stage regulator.
Inner Frame
The inner frame located in the oral nasal
pocket is key in properly mounting a second
stage regulator into the Spectrum FFM.
The purpose is to add rigidity to the mask
while adding the least amount of weight as
possible. When the inner frame is properly
implemented, the oral nasal pocket is
significantly strengthened. This reduces the
amount of “push / pull” effect of the second
stage regulator when inhaling & exhaling,
as well as limiting the range of motion of
the regulator.
