First impressions diving a chestmount rebreather

[Fat old english bloke]

Poor access to your drysuit inflation seems disqualifying if there is not a good fix. What's the suggestion for that? Don't dive dry?

You get used to it soon enough. It’ll never be as easy as BM, but the awkwardness quickly goes away, even with thick heated gloves, glove rings, etc.

Hi
I have been diving the Triton for years and also have a few oxygen CM unit and got a few dives with the Chop.
-Necklaced reg is not a pb,
-accessing the DS valve is not a pb after you get use to it (from right or left),
-reading the Oxy gauge is indeed a bit of a hassle but you don't check that often and once you know were to push the right side of the bag and/or pull the gauge in the front, you don't even think about that,
-the Monox is being replaced by a new unit which will also be a computer and a HUD,
-yes, it needs a bit of adjustment to get it "nice" and you can also turn the breathing loops at the junction with the CL to get a better position and the upper clips need to be close to the D-ring (you only use one side of the double ender and not both side)
-I don't get this "nose pb", sorry.
Anyway, like with every piece of equipment, "adaptation" is the key word

I know of the Tec-Me head with the Narked cable which would remove the Monex. Are Triton changing to all Shearwater now?

Not Shearwater, some other lot. Can’t find the literature now otherwise I’d stick it on here.

The V2 Triton is there. You can even get a 3kg canister:

I don’t think I’m smart or patient enough for a CCR no matter where it’s mounted.

Interesting.

They've developed a new proprietary Monex computer called the NGC (next gen computer), now in colour with separate battery holder and their own HUD. They do allow a Nerd or Petrel to be added (not both), but the Monex/NGC is still required.

Wonder if they'd sell it without their proprietary electronics so we can just use Shearwater Petrel, Nerd or Shearwater HUD?

Not being a Shearwater fanboi, it's just that I trust Shearwater and have three of their computers which I'd like to reuse. Also the Shearwater cloud app is OK and very simple to use as it integrates exceedingly well with phones, tablets and desktop computers. Put it this way, I'm damned if I'm interested in anything else especially from a small company that could stop trading at any point. Same goes for the AP Inspiration 2020 electronics.



Interestingly on that video, there's a few minutes of people diving Tritons in clear warm water. This shows some quite different sized divers and it is interesting to see how the loop hoses vary in how they float around the diver's face. At least one has the loop quite tightly bent around their cheeks, probably impeding their head movement.

I don’t think I’m smart or patient enough for a CCR no matter where it’s mounted.

Rebreathers are a definite commitment in terms of both money and time to dive them.

Once committed and you've that first 100 hours on them, they become a lot easier and enjoyable.

Was strange to go from being extremely comfortable with my existing backmount rebreather to be very uncomfortable with a chestmount one, simply as I'm not familiar with it. Am certain committing a few dozen hours on the unit and it'll be just as easy to dive.

Having said this, playing on open circuit sidemount over the past few weeks has been lovely. So easy to dive compared with a rebreather that needs hours of prior preparation. OC: throw it on and dive. Simples.

Awesome dive brief/log, Triton is one of the units I really wanna try next, so you already saved me some research doing a „comparative writeup“

The blocked nose/sinuses worries me about diving chestmount. It was my first time on a Triton, but the symptoms concern me as it could be due to the additional loop pressure with chestmount. Only another dive would tell. Curious if others have experienced this before.

This is something i have been looking for leads on since I did my mod1 in May (only tried and trained on one single unit, kiss sidewinder) — haven’t found much so far
I did 12 days of sidemount OC right before the class, and did have very minimal sensation of blocked nose, but it’s not like I was using it, and once I went out of the water all was good
When diving on the loop, I for sure I felt it more (the sensation of blockage), and I also was (trying my best to, first time on CCR) managing over filled loop back to min volume through my nose
Not so fun surprise, snotty mask

I don’t think that was a „pressure“ thing (I also had a bcml not a chest mount, and nothing to compare to), but maybe a more generic curiosity on venting the loop through the nose, and mask „gurgle“

Thank you for making me feel less crazy

The Triton is CE with the NGC so you won't get it without it.
The NGC has nothing to do with the Monox which was only a monitor...and a bad one.
The NGC is going to be a full computer soon so the SW (Petrel 3 or Nerd) would be an extra add-on.

M3S, the company making the Triton, has an intensive military market so it might be small but secure with a substantial captive market.

Don't worry about the loop. As I said before, you just need to get your position by turning the base of the loop at the CL junction and after that, you forget about that. But it is true that coming from BM unit, it may feel different.

Warm water, cold water, open sea, cave, this unit is really good anywhere with any set-up you like.
I personally use it with just the oxy tank, no wing to "play" in the 6M range as a pure oxy rb or with a mini-SM wing and an S40 dilout for simple rec dive , or with a double BM tank and stages-deco for cave and deep dives.
Some people use it as a BOB and they took it well below the 200M mark.

Are the stage cylinders rigged to carry weight on hips rather than chest? With steel stages on backmount JJ-CCR I found it comfortable to use shortened riggings with adjustable cam bands closer to mid-cylinder.

How far upright before experiencing excessive pressures?

How does it dive with a single steel cylinder on the back, or mini-twins?
Anyone diving inverted (valves down) backmount or sidemount cylinders?

I heard that sustained positive pressure on the soft palate/nasal cavity can lead to conditions, tissue stress and/or air leaks.

I was thinking about this. When I was diving with a horse collar BC the drysuit inflator was towards the side (right). Maybe this doesn’t work for sidemount?

It really wasn't a problem at all for me when i had a triton. my hand slipped in easily under the bag to inflate/deflate and if i wanted to disconnect using both hands it was also very easy
