FEATURES BENEFITS
Bodyguard II The fully electronic monitoring
unit provides you with all the information you
need throughout an operation and can be used with
PSS Merlin telemetry system.
Bajonett rings Enable a quick and easy assembly
and disassembly.
New
Breathing air cooler To reduce the temperature of
the inhaled air, thereby minimizing the physical
exposure / stress, the breathing air cooler can
be filled with ice or as an alternative the
re-useable alcohol cooler can be used.
CO2 Absorber The streamlined CO2 absorber ensures
a high degree of breathing comfort. Depending on
your individual needs you can choose between a
disposable or a translucent refillable cartridge.
Optimal wearing comfort The ergonomically shaped
carrying shell, the low device weight and the
improved, well padded shoulder straps and hip
belt give a higher wearing comfort.
Spring loaded breathing bag The slight positive
pressure throughout the entire breathing circuit
generated through the springs protects the wearer
from toxic ambient gases.
Anti-Vibration-Strap The Anti-Vibration-Strap
ensures a smooth transport on vehicles.

DEHYDRATION
What is dehydration ? Medically, it is a
condition in which the body contains an
insufficiant volume of water for normal
functioning.
1)

• Signs of dehydration ?
• Thirst
• Headache
• Loss of performance
• Low endurance
• Rapid heart rate
• Elevated body temperatures
• Extreme sleepiness
• Fainting
• Vision may dim
• Delirium

HYDRATION
How much water is sufficiant ? This is difficult
to answer, because one needs to find the balance
between water and weight. Water loss
(examples) 1 gallon 3.785 liters - 2.5
liters / day Normal day (England) 1) - 3
gallons (11.4 liters) Hot weather 2) - 1.5
liters / hour Military operation in hot
environment 3) - 1 2.2 liters / hour Heavy
physical exertion in heat 4) Counter
measures Drink water before, during and after
your tasks. Up to 2 gallons (7.6 liters) / day
or for example 4 cups (1 to 1.2 liters) an
hour.5)

HYDRATION
Would 2 liters be acceptable ? 4 cups (1 to 1.2
liters) per hour are recommended. That would be
between 2 to 2.5 liters for a 2 hour
operation. We can not give the answer, but we
can offer options on where to place water
containers that can be bottles or
bladders/tubes. CamelBak offers a large variety
of solutions, adaptable to our connection. On
the following pictures you will see a 3 liter
bladder worn on the chest. This is only used as
an example.
