OCTOPUS (Alternate Second Stage) USE
The diver controls available on the Zeagle standard Envoy second
stage make it an excellent choice for Octopus use. An Octopus
Regulator is often subjected to conditions that may cause a free-flow.
For example, jumping into the water or swimming in a strong current.
To minimize this, move the Dive/Pre-Dive Lever forward to the
“-”
Minus position. When the Octopus Regulator is needed for deliver-
ing air to a diver, the Dive/Pre-Dive Lever is moved back to the DIVE
“+” Positive position. Although breathing resistance will be somewhat
greater, the regulator will still deliver ample air on demand if the Lever
is accidentally left in the Pre-Dive position. Longer hoses are available
from Zeagle for Octopus use.
WET BREATHING
The Envoy second stage is much
“drier” than many other second
stage designs during use. However, it must be remembered that water
(including the
diver’s own saliva) will always settle to the bottom of the
case. If the diver is in an unusual position (i.e. head down or upside
down looking upwards) the exhaust valve is no longer at the bottom of
the case and the mouth tube is. This means that water will settle in the
mouth tube area and sometimes is ingested by the diver. A tendency
to wetness is aggravated by slow exhalations while inverted. This is
because the exhaust valve is flapping open with little air velocity, thus
letting water in. Of course a regulator that begins breathing wetter
than it has before, should be checked out by a technician, but avoid-
ing long periods of inversion, and using shorter stronger exhalations
if inverted, will keep the interior of the regulator drier.
PRE-DIVE CHECK
1. Before diving with the RaZor. Check to be sure that the black cap
is in place on the quick-disconnect filler (see fig. 3)
