Lambert Rebreather Technology
utilizes the HydroSpace Engineering Explorer Dive Computer/Decompression
Meter for controlling the FROG modular diving system. It is designed
to be simple and easy to use when diving with closed and semi-closed
circuit rebreathers.

WHY
WOULD YOU WANT TO USE A CLOSED CIRCUIT SYSTEM?
Prior to 1995 I
would have answered that question with: there is no way sport divers
should consider using the existing closed circuit systems. While
the advantages are significant, the cost to purchase, maintain and
service, combined with the additional skill requirements make closed
circuit systems special application devices.

The major difference between 2005 and
the prior to 1995 closed circuit systems is the application of the
digital microprocessor. Prior to 1995 the user had to maintain a
constant vigilance over the operating system. The units were not
"user friendly."
Errors could be made by the operator
during servicing and use that the system would not identify for
the user. Omissions and errors could prove deadly. The digital microprocessor
that is in the Frog monitors the system from the time it leaves
the manufacturer and during the entire life of the unit. The unit
never sleeps; in just go inactive when you do not use it. Some vital
functions of the system that are constantly monitored when in use:

The scrubber is a good example:
In prior to 1995 units there was no way to tell if:
- The scrubber
had been serviced,
- The scrubber
was working.
- The scrubber
was exhausted.
The 2005 Frog uses a pre packed scrubber that has a use date and
has the quality and quantity of the absorbent assured by quality
control inspectors in an FDA approved facility. The Frog controller
monitor the replacement of the scrubber to insure it is changed
prior to use. The scrubber performance is monitored during use by
temperature probe to warn of exhaustion or operation outside of
desired parameters.
Constant monitoring of the scrubber by the controller
relieves the user of the obligation to maintain a constant vigilance
of the system. The system will warn the user with audio and flashing
visual LCD displays of any system performance that is out of desired
parameter. Time to use, oxygen percentage, gas cylinder pressure
and system power is monitored the same to relieve the user of the
need for constant vigilance of the many system functions.
So, I can answer yes and give adequate
reasons for a sport diver to use a closed circuit system. The advantages
are:
- The time of
use is absolute, one hour means 60 minutes.
- The loss of
body heat is decreased by up to 70%.
- The silent operation
allows enhanced user hearing.
- The unit is
lighter than comparable open circuit units.
- The gas efficiency
approaches 60:1, providing longer use times.
- The cost of
use is less on a minute by minute basis.
- The system is
safer due to dependability, system options, system monitoring
and advanced warning capability.
ALL
THIS IS BASED ON ONE CONDITION:
THE CLOSED CIRCUIT SYSTEM YOU CHOOSE
IS A FROG MK-II MADE BY REBREATHER TECHNOLOGY
