Best CCR in 2025-2030 Rebreather Markets

[Wibble]

Capitalizing on the chance here, an aside to that aside
You dive a rEvo right? How do you have the 5 cells routed? 2>Petrel 3>Nerd?
And I assume you fly it on eCCR variant (not H or M)? (Sorry if I get things wrong that’s the depth of my revo knowledge)

I’m just thinking about the part about couple minutes of discrepancy in deco time and if it has something to do with the sensors as well (probably not with diveCan)
Anyways good to learn about the system (considering x-over)

I do dive a Revo.

There’s five cells; 1,2,3 are routed into the wrist-mounted Petrel via the DiveCAN bus (digital, 5 pin cables). Cells 4,5 are routed to the mouthpiece mounted Nerd using analog cables (4 pin). There is a third cable in the cell tray for sensor #6, but there’s no room in the tray for that. This could be used should your Petrel crap out and you can then connect three cells to the Nerd, OR you could add a splitter cable (sold by Narked@90) to have one cell shared between the Petrel and Nerd.

The Petrel is the controller so it drives the solenoid via the DiveCAN bus.

Revos normally have an “orifice” (also known as a Constant Mass Flow/CMF) which leaks a fixed flow of oxygen into the loop regardless of depth, typically around 0.6 litres/minute (flow needs to be set for the diver's metabolism). The CMF needs a modified oxygen first stage to fix the IP and not change by depth as all other first stages operate.


Now, because the Revo has both an orifice and a solenoid, they're referred to as a "Hybrid" CCR (hCCR): neither a

• Manual CCR (mCCR - has an oxygen orifice, no solenoid or controller)
• nor an Electronic CCR (eCCR - has a solenoid, no orifice).

This means that the orifice reduces the amount of times that the solenoid fires; decompressing for hours and the solenoid never fires saving the battery as the orifice is pumping oxygen in at the same rate I metabolise it.

The benefit for me (sorry, I don't care for the orifice haters!) is that I can leave the setpoint at a few points lower than I drive the unit manually. For example, I set the setpoint to 1.2 and drive the unit manually at 1.3. If I'm distracted and don't notice the PPO2 dropping, I will get the hiss of shame as the solenoid fires. I like that as I'm forced to monitor my PPO2 and anticipate what my PPO2 is.

I know that some people will throw a hissy fit at that; they totally trust their wonderful eCCR and bully for them.

I also drive a manual (stick shift) car with a handbrake lever; I despise automatics and the electronic crap in modern cars.


And to answer your last point: there's always slight discrepancies between cells 1,2,3 and 4&5, plus with the 4"/10cm difference in depth throughout the dive between my wrist and face.

Since you didn't seem to get a joke (or really are a bot), this CCR is nothing but vaporware for more than a decade now. It basically became a meme at this point.

I don't understand why a few ppl here seem so obsessed n frightened that a question could possibly be asked from a bot. why do you even care who is asking the question. It is a waste of time and energy to become an paranoied detective who try to analyze the personality or intentions of people asking a serious question.

That’s a very good conditioning mechanism

Thanks btw a lot for that user-pov crash course, way better than what I heard at boot about the unit and its diving intricacies

Cuz datamining a free, public forum is not very nice.

Because a Bot is not a serious diver.

Hmm, OP restricts profile views, and Google Lens tells us that the profile picture is stock footage from a photographer called Roger Horrocks.
Bot confirmed?

I wouldn’t be so quick to jump to conclusions, privacy and hiding behind „stock“ photos is common internet behavior

What about your profile picture, paranoied detective confirmed ?

To satisfy your curiosity: I do know about a major shake-up in the CCR market that will absolutely revolutionise closed circuit diving and bring modern technologies, including an AI-assisted decompression algorithm, to a proven, durable and rugged CCR design. Sadly I cannot disclose much but I do have a pre-release photo - the unit should be behind the yellow exoskeleton that is simple to release yet prevents corrosion and dents, especially on boats.

The unveiling will happen at GoDiving industry event on the 1st of March at NAEC Stoleneigh Park in Coventry. Hold tight.

Maybe it will reach a 30 years market benchmark!
