In Water Operations
The top leg of the spider can be loosened once in water. It is possible for the top
leg to be too tight which will cause the mask to be pulled up too far on the face.
The main purpose for the top leg of the spider is to provide on deck support of the
mask. Some divers may prefer the support of the top leg while in the water, too.
NOTICE
Proper hood fit and spider adjustments are needed for the
mask to fit comfortably and function correctly.
3.5 Purging Water From The Mask
If the mask is removed and replaced underwater, it must be cleared of water
(purged). This is done by simply holding the mask firmly on the face, keeping the
regulator in a low position, and depressing the purge button. A slight momentary
overpressure will be felt, followed by complete removal of all water from the in-
terior of the mask. A mask completely filled with water, should take no more than
3 seconds to completely purge.
B
CAUTION
In the unlikely event the mask should fill with water, depress-
ing the purge button should clear the mask. In the event of
a complete continuing flood, the adjustment knob should be
turned out to cause a regulator free flow. The diver should
then immediately assume a face down position in the water to
prevent the mask from flooding again. At this point the diver
should exit the water immediately.
