Dive Talk Go Rebreather

[InWay2Deep]

Many thanks for those responses very helpful.

Im learning this is like buying a car…..
I have been asking around reading manuals and generally trying to build a base of knowledge. So your responses are very helpful.

Is the primary reason the go is unsuitable for trimix the scrubber duration? Or are there structural issues solenoid size or type, or the shape of the canister that means it will not work well with tri mix?

As I am looking to unlock the 60-80m range it seems that a choptima or triton FX are eager options that will travel and accommodate trimix. (Ignoring the EvsM considerations).

Is ths a fair statement?

Cheers

Just so you know the GO is an mCCR, so no solenoid. I think the reason most people say No GO for trimix dives is the duration of the scrubber. Typically in Tech diving you want a LOT of margin for safety. Most use the rule of 1/3's. This goes for EVERYTHING, not just gas. Battery run time on lights/scooters/heaters are also included in that rule. As should your scrubber duration. So unless you are planning quick bounce dives the GO does not leave you much margin for safety due to the short scrubber duration.

There is nothing inherently different about the GO than any other mCCRs. You have a loop in which you breathe, you inject O2 to replace what your body metabolized and you have a scrubber to remove the CO2. That's it. Pretty simple. Nothing about that (or really any other piece of gear) cares if you are running TriMix through it, diving it in a cave, or open water. The only real thing you need to concern yourself with is the depth/duration rating of the gear.

I don't think scrubber should be included in the rule of thirds regardless of the severity of the dive. You have bailout gas (or a bailout rebreather) to take care of loss of functionality of your rebreather.

Rule of 1/3 for scrubber duration?!!!!! Really?!!!! Do you dive CCR?

I actually have some love for Dive Talk since their videos in part inspired me to get certified some years back, and I still watch some of their videos as entertainment.

However now that they have a training agency and are manufacturing/selling equipment, I'm a little worried at their lack of professionalism.

They are now pushing this CCR to inexperienced divers as a solution to high gas consumption among other things, and that sounds like a horrible idea to me. The way they ridicule the criticism they receive and the uncritical way they use their channel to push sponsored products and now their own, gives me an uneasy feeling.

The defense that they're just entertainers and shouldn't be held accountable clearly holds no weight at all.

I lost a ton of respect for them over this past year.

The channel used to be awesome, covering legitimate topics like the ones we cover on SB in video format along with their reaction videos.

Now it’s all blatant marketing and clickbait thumbnails. They do not take any kind of criticism well and pander to the most common denominator in their fanbase. You can’t have a serious discussion on their Facebook group, for instance, without people losing their minds. Maybe Scubaboard ain’t that different on that last point.

They also get very preachy about anyone vocalizing criticism and “judging how other people dive”, yet they built their whole said channel on doing just that.

I recently spent two weeks diving with a Go on the boat and I was really impressed by it. The unit completed 7 out of 13 dives without flooding. I was incredibly impressed as after looking at it, I didn't think it would even be close to 50% let alone beat it.

As someone at the first step of the RB journey is a 47% flooding rate good? Presumably this is not catastrophic flooding or flooding leading to caustic gas, just a little water in the loop? apologies for the lack of knowledge here if this is a stupid question.

1/3rds of a scrubber? I dont know anyone tossing 1/3rd of a scrubber. What unit are you diving? What temp, depth and duration do you consider the scrubber 100% spent and what's your 66% temp, depth, time?

… how many dives completed on the loop?

The only time a unit should flood is user error or a very rare mechanical problem. If the unit passes pos/neg test, it shouldn’t generally flood on the dive.

I would not personally consider 47% flood rate good.
I have completed probably 5-700 rebreather dives and I have had two floods requiring me to bail out and end the dive on OC.
Both were caused by me doing stupid things and not a unit malfunction.

7 out of 13 were completed on the loop. The rest were ended on OC

I would agree with that statement.
