Some folks use it for cave exploration, british style. Ie in small, shallow, muddy holes, where one might have to pass only short sumps. Advantage is that they are easy(er) to carry than full size cylinders.

Ok, since everyone else has already gone off the rails, I can happily add my piece of survivor bias. On my last tech dive trip, after 6 consecutive days of decompression diving to 50-52 meters (165-172ft), I was on a plane home some 8 hours after surfacing from the last dive. So was my buddy...

@Kevin Floyd since you were recently asking about DIR and are considering going tech, I would strongly recommend to not get the Suunto. The reason is the proprietary RGBM algorithm. For tech diving, imho, you want a computer that runs the same algorithm as the program you use for planning your...

Well... also bear in mind the legal implications of offering advice of when it is safe to fly. Anyone with a sane mind will for sure err on the side of caution, to not be sued by litigation-happy Americans. That’s why a lot of dive computer manufacturers do not offer any kind of no fly...

This. I‘m nowhere near the level AJ is, but I do dive caves and Trimix :-) Breathing techniques is the wrong focus, anything else than normal is worse. As soon as you consciously try to influence it, you’re headed the wrong way. Instead, focus on diving skills: buoyancy, trim, propulsion...

If you ask me, the MTX is a shiny version of the FSR ... not sure if anyone has been able to measure a performance difference, but the price difference is for sure ;-)

DST with the 5th port has the best routing by far. Routes the same as the popular Mk25 alternative from the other brand. I dive Apeks DST with 5th port in my doubles amd am very happy with it. Second best routing, but far more expensive is the FSR (XTX100/200 first stages). The angled ports...

@Kevin Floyd I agree with the others. Get a proper light when you first buy one. I was in a similar situation as you before fundies. What worked for me, was this: Initially practice in places not too dark or too deep, so there’s no need for a light. In the beginning, buoyancy and stability are...

Pretty sure that this is what my fundamentals instructor explained to us. Maybe they changed it in the meantime, but this is from the fundamentals course materials (version 5.1 from 2015): Think of it like GUEs stance on computers, which boils down to “we recognize that todays computers can...

@Kevin Floyd since you mentioned fundies in the OP: as far as I’m aware, GUE does view the cordless lights as “DIR”, so long as they have the right burn time and beam pattern. BUT: to get a tech pass, you need to demonstrate that you are proficient with the corded can light, after that you can...

What PcfAj said ... for me one if the biggest factors against cordless is the weight. If you want a light with decent output and decent burn time, today’s cordless versions still tend to be fairly heavy. For me, the corded can lights are much more comfortable to use, No matter how high tech your...

Fun fact: many chinese people (non-divers) use the hang loose to mean the number 6

@tmassey thanks for the comprehensive writup! The interesting question for me would be: let’s assume you have cave training, full cave with all bells and whistles, and you also have full trimix training. So all the skills you described (line work, zero viz, deco, etc) should be second nature...

Well, lets call it a sign for a stop then. Some rec divers indicate a safety stop by hand with spread out fingers on top of three fingers of the other hand or something like that. It means 3min at 5 meters. I’m sure there a many more signs for this stop or other stops. To a tech trained diver...

In tech training the pinky is standard and will be recognized by anyone who trained with a reputable agency. In recreational circles there are likely many different signs.

ewww ... do they still have that student workbook that shows an instructor demonstrating a gas switch ... while kneeling on the bottom? Regarding the original question: as mentioned above, no wrist slates in GUE or DIR in general.

Hi @matjazr ! Would you have some more information on cave diving in Slovenia? Where are the caves, how deep, access rules? I’m thinking of planning a trip there :-)

If you have the discipline to pull this off long-term I applaud you. Just don’t underestimate the lure ... my guess is that you will always wonder ... „What’s around that next corner? It’s really close ...“ „Where do the jumps go that I keep swimming past?“ „That super decorated room further...

Well, some people like to make several dives a day, maybe even on consecutive days. On a liveaboard that would be quite common. In these cases, Nitrox is a huge benefit, because at the end of the week, the folks on air have NDLs of 10ish minutes while the Nitrox folk have 20s. Fair that...
