COMMAND AIR
HIGH PERFORMANCE ENGINEERING!
Totally effortless breathing under any conditions. The heart of this regulator 
is our state of the art Balanced Demand Valve System, which provides 
maximum air yield, regardless of depth. The external adjustment controls 
allow you to fine tune response to your specific requirements regardless 
of environmental conditions. Sensitivity control: Increase or decrease 
breathing resistance at a touch. Prevent free flow irrespective of face up 
or face down attitude. Turbo Boost Control: This allows the deep diver to 
increase air flow to the maximum without any increase in inhalation effort.
This world class regulator is designed to provide reliable, smooth even 
airflow for safe comfortable diving regardless of depth and water conditions 
and performs flawlessly in both sub arctic and tropical waters. Sold on the 
basis of safety, reliability, performance, durability and serviceability. 
This unit has an unblemished record and is backed up with an original 
owner lifetime guarantee. Praised by both professional and recreational 
divers the Command Air has earned it's rock solid reputation reputation. >>>

COMMAND AIR TURBO - Mk 1
Offers effortless breathing and simplicity of operation while retaining the same 
high performance as the Command Air. The turbo regulator is very popular 
in diving schools or as the alternative source of air. Turbo Boost: to 
vary the assistance of the venturi effect. This allows the diver to increase 
air flow to the maximum without increasing inhalation effort. Ideal for deep 
dives and situations of heavy demand. When used as an Octopus, the 
boost is turned down to prevent free-flowing when entering the water. >

EXPLORER   II - Mk 1  
Classical down stream demand valve regulators with very high reliability. 
Their simple design has been repeated in many regulators around the world 
for the last 30 years. The latest version of this system is the basis of the  
Explorer ll and Octopus regulator. They are made of strong lightweight space
age material and guarantee exceptional performance and long life. >

HOOKAH
Implements the classical down stream demand valve design but has a simple 
and unique non - return valve incorporated directly into the L.P. valve. The 
regulator is designed for the surface supply of air, which has substantially 
lower pressure than standard second stage Regs. To maintain smooth and 
adequate performance a special high flow orifice is used.
