2.9 Recommendations For Donning Or Removing The Exo-26
Become familiar with the way in which the mask attaches and properly fits your
face. Because the face seal fits the face well when loosely fitted, it is easy to as-
sume that this is how the mask should be worn. This assumption is incorrect and
can cause negative results when diving.
Wearing the mask with an incorrect adjustment will not allow the divers face to go
far enough into the mask. The air space inside the mask will be excessive causing
possible buoyancy and problems with the fit of the seal and oral nasal. The main
portion of the face seal is very flexible and should be stretched to form a proper seal.
The spider (head harness) and buckles are also important for proper function of the
face seal. The spider legs and rear head cup are all shaped to pull the mask up to
the face. The head cup should be placed as low as possible to reduce jaw fatigue.
The buckles swivel (except the top) to allow the spider to find its natural correct
position. Do not try to force the buckles to swivel completely around. They are
allowed free but limited movement to keep the spider from becoming entangled
while the mask is being handled.
2.10 Donning The Mask
1) Make sure that all other gear is properly donned, the air is on, and regulator
functions and communications tests have been done.
2) Make sure all 5 legs of the spider are loosened all the way.
3) While holding the mask in position by the chin cup, begin tightening the spider
at the bottom straps, but not all the way.
4) Make sure the cup of the spider is centered on the back of your head. It should
be low, but not down on your neck.
5) Next, tighten the top two straps above the temples. Alternate between top and
bottom straps until the face is positioned properly and snugly into the mask.
The mask is usually the most comfortable when your nose is partially into the
nose pocket. The top center strap can be tightened slightly to give support to the
mask while standing by for water entry. Once in the water this top strap may be
loosened. Sometimes, if the top strap is too tight and the diver’s hood fills with air
while diving, the hood pushing against the top strap may cause the mask to lift up
on the face. The spider may be readjusted during a dive.
