Recently I met
Martien at my home. He took his brand new JJ-CCR and offered me
the first glance of this very nice rebreather. Martien followed
his Inspiration rebreather training in the Netherland with
IANTD. John Dekker his trainer, took him through level I, II and
III. Martien dives his unit on the North Sea for people who do
not know this Sea, it is not very easy diving. Many times there
are currents and visibility is not always at best. Since Martien
loves to dive in wrecks he wants a reliable unit and found this
in the Inspiration Vision rebreather. Unfortunately for Martien
he is a
short guy, so his arms are too. (although these arms have a
absurd diameter ;) ) He had troubles with the front mounted
counter lungs of the Inspiration and decided to try the JJ-CCR.
With pain in the heart he switched from Inspiration to JJ_CCR.
Together we took several hours to compare this new rebreather
with other units. I was happily surprised to find a very well
build high quality unit. Of course there are advantages and
disadvantages compared to Meg or Inspo, but I have to say I was
impressed with the high standards of this rebreather. In other
words: a great and very well build rebreather. Know how of
divers and not of designers. There are positive and some
negative aspects but see for yourself.

Impression:
|
|
|
|
|
The unit is made with very high quality materials and offers
many possible configuration. The "hardware" is extremely heavy
build. The unit is 32 kilo and is very stable on his stand. The
controller is made in Canada and not a part of the rebreather
factory. Also there is no CE marking so far but that seem to be
changed soon.
To me the unit seems very reliable, very well build for a
competitive price.
