Training and Practice for Safety
As with any piece of high-tech equipment, the Guardian FFM does require
additional training and practice. Air sharing in an out-of-air situation is more
difcult, often requiring bailing out of the mask (depending on your gear
conguration). See “Training & Emergency Procedures” on page 13
for detailed instruction on this topic. When properly used however, the
Guardian FFM provides an additional margin of safety to diving. Proper
use of communications to relay a problem, combined with the security of
the ve strap harness system securing the Guardian FFM, adds a degree
of safety to diving not found in standard equipment.
