OCTOPUS (Alternate Second Stage)
The diver controls available on the Zeagle (p/n 320-8110) Z Octopus
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 mini-
mize this, move the Dive / Pre-Dive Lever forward to the “-” Minus position.
When the Octopus Regulator is needed for delivering air to a diver, the
Dive / Pre-Dive Lever is moved back to the DIVE “+” 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 posi-
tion. The 36” Yellow braided hose that comes with the Z Octopus, is
stronger, lighter and higher flow capacity than standard Scuba hoses.
WET BREATHING
The Z 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 regu-
lator that begins breathing wetter than it has before, should be checked
out by a technician, but avoiding long periods of inversion, and using
shorter stronger exhalations if inverted, will keep the interior of the regula-
tor drier.
PRE-DIVE CHECK
1. Before mounting any Scuba regulator onto a tank valve, you must open
the valve briefly to blow out any water trapped in the outlet area of the
valve.
