Third day with Boris.
Meeting at 7.30 o'clock, beginning of the pre diving procedures.
All it' ok , up to the test of negative pressure.
The SG unit and mine, lose from the connection of the inspiration hose.
After various attempts, we realize that the Orings must not have greased , otherwise they to go out of their center and to damage it.
Changed o ring, all ok, the test at the end doesn't take very more time of a test with any unities, if done following the procedures.

At the port washing and control unity.
Theory with procedures for possible malfunctions.
My confidence in the Boris and the pleasure of dive with it increases of time in time.
Note: I have changed the original mouthpiece Poseidon, with a spare of my MEG.
Another story, best breathing and any pain to the jaws at the end of the Dive.
It's a unit with the great potentialities, perhaps the best on the market in this moment, with some things in progress of setup.
Perplexed from: Manual injectors of O2 and diluent - hard and diluent with low flow
choice of the batteries - rapid consumption
Fragile structure
connection jack of the sensors - I have some ugly memoirs on the reliability of this connection
Laboriousness to change the sofnolime, asks for time, calm and space, I would see complicated change it on a normal boat diving during a navigation
Not to the height of the unity:
practically any accessory, not even a key to open the batteries compartment VR3
Cylinders painted in the garage
labels HUD lost after 2 dives
An exceptional rebreathers, however and I am happy to possess the two rebreathers that personally I hold the best on the market in this moment.
I appreciate the Boris for its characteristics of endless redundance, facility of breathing, everything behind
I appreciate the Megalodon for hits sturdiness, simplicity, safety and facility of breathing
Two rebreathers to perhaps be used for differents objectives
You excuse me for my language and thanks for your attention.
It is difficult for me to express some concepts in English and at times the sense can result wrong
PS. These are personal opinions and I don't perfectly know still the unit, I wanted only to share with you my impressions
I can organize in may some try dive in collaboration with my Instructor.
If you are interessed please contact me
Best regards
Aldo
