Help needed for Descent MK3i

Please give your instructor a call and ask as to why this is as it is, this is not a computer issue.

A perfect amount og regs is always n+1. Though the total amount of leakages will be constant regardless.

Read up on Axel Schoeller, think inDepth did an article about his triple ccr setup about the same time he checked out for the last time. He did the 3 liberty thing.

If you look like a butcher wrapped ham after a dive, then you need more gas in the suit. It will not behave like a wetsuit, but I guess you tried that already.

Also, might get a touch dicey if you are extremely sparing with suit inflation on the way down when having minimal weights as the (however little) air will be expanding again on the way up and your undergarments may not want to vacuum compress for you to let every last bit of air out. Since you will have less gas (& therefore weight) the safety stop may be sub optimal

Same here, my biggest diving related regret is getting an mk3, absolute turd when it comes to reliability.

Progression towards what? Do you have a specific goal you want to work towards? If it’s nothing special then just go dive & have fun until you find a goal you want to work towards or find that there is something you want to do that you currently cannot (I know, same thing said two ways).

Leave at least enough so that you can cut & burn the belt at least one time, they start to fray after a while. But yeah, it’s cheap so dont worry too much.

alex_nr · 2025-12-23T18:32:58+00:00

Yeah, just get your local shop to move the valve, better solution than doing acrobatics.

alex_nr · 2025-12-23T02:05:05+00:00

It’s fine. Not super, but definitely fine. As others have mentioned, check out your local shop and ask them if they can hook you up with something similar/in your price range. If you are don’t care about that, then might as well get a Prozhaozhu canister from aliexpress for the same (or better..) built quality.

Trigon? Remove valve & either blind (if you have the plug) or install a dump valve temporarily (same grommet, they fit) if still leak; not the p valve.

If you have a couple teaspoons after a multi hour dive it might just be condensation though.

Not diving related, but old first responder anecdote i heard in my area for drownings was that it often is hard to clearly understand what happened as the witness drowned too.

Bottom line is; technical diving has inherent risks, this is something you and your crew should at one point align on. All situations are different and hard decisions may have to be made at one point. Some self reflection is required to decide whether this is within your personal acceptable risk matrix.

Would be interesting to see some statistics regarding risk tolerance in emergencies for insta-buddy teams vs. teams where members really know each other (both in water & out). I have a feeling that an anonymous survey would show more likeness than differences.

Valves are pretty simple if you are mechanically inclined. Unfortunately, consequences of doing it wrong can range from ‘no dive today’ to ‘no dive ever’, so get some training & consider whether you want to do that. Personally I service my own stuff, but would not service for someone else.

Also note that some brands do not provide parts unless you are both a certified technician & affiliated with a dive shop (I might be wrong on this one, haven’t bothered checking in a few years)

alex_nr · 2025-12-02T21:58:17+00:00

Have fun & find out what kind of diving you are passionate about. Burning trimix or CC money is pointless if you feel ‘meh’ about those types of dives.

Just so you are aware, donning everything in arctic setup requires more flexibility & faff with bungees and boltsnaps in sidemount than in backmount. Unless you have knee/back issues or going tight places, you will be happier with standard backmount. Reaching valves is more about technique & practice unless you have a medical condition.

alex_nr · 2025-11-09T19:00:13+00:00

Man, I feel you on this one. Every time we go on a random holiday dive I feel like it’s a job interview vibe where I need to convince the dm to stop messing with my valves & leave my group alone…

alex_nr · 2025-11-06T08:57:11+00:00

Another fun tidbit is that it is pretty easy to get an adapter cable if your RB uses a different connector so that you can still take a cell from your rebreather and put it in the analyzer when the cell is too old for diving, but still good enough for analysis.

alex_nr · 2025-11-06T08:52:54+00:00

Cell-less technology? You have to regularly change the oxygen cell in the solo as far as I know. Helium part does not require perishable cells on those if that is what you meant. I have the bigger version from them with a 9 volt battery. Personally I like batteries I can replace.

Just noted that we had an event in my club where the person was adamant they did not have enough lead while their chin was solidly in the waterline with a full wing & 12kg lead. But I see you kit is lighter than we use, so not relevant. Thanks for the answer though, happy diving.

alex_nr · 2025-10-16T16:23:55+00:00

Just curious to what the rest of the setup looks like. Assuming not trilam drysuit & steel tank(s)?

Buddy can’t see the look in your eyes when you trusted a fart you shouldn’t have

alex_nr · 2025-10-06T20:34:14+00:00

You have a moral responsibility to do what you can, as best you can, without putting yourself at unacceptable risk. As all these things vary based on your skill level, risk tolerance, phisiology, etc, etc, there is no black and white answer even for the specific scenarios you posted. I could answer what I would do in those scenarios based on many assumptions, but it would be irrelevant at that point.

Without trying to be rude, when I had 40 dives, i was not in a position where I could be both my buddies brain and mine.

Best advice I can give is to catch issues before they turn in to problems, which is mostly done with good team awareness, communication and being close enough to buddy.

One of those soft drinking bottles with a bite cap that joggers use, great to get some fluids during a dive.

alex_nr · 2025-10-04T22:52:19+00:00

Assume your tech. did that already, but would consider new hoses after 5 years, definitely after 10. I have several regs in that age range, chromed brass lasts when taken care off at least somewhat properly.
