Snubbish way to clean the o ring by a piece of toilet paper 😂
It is anodized aluminium
Good little instructor there!, haha, lol, aw, lil dudes gonna be a natural methinks
why is every company releasing chest-mounted rebreathers? They don't provide any advantage in terms of profile over back-mount.
Is this ok at 16 dives ?
Well done on the video bro, it was really insightful and a great review. Dive safe, have fun! 👍🤗🔦🍻
brilliant! thanks for sharing
Im awaiting my first ccr unit. Main reasons for me: - I’m fairly susceptible to depth narcosis. Trimix is way too expensive to be diving every single time I want to go to 30/40 meters. On the CCR it’s easy and “affordable”. - My main-buddy uses around 50% of the air I’m using. Diving deep is possible, but I’m the limiting factor for duration. - I’ve had a trip to the deco chamber once before after some deeper wreck diving. I can’t wait to be doing optimal decos with a fixed set point. - You look cool also f%}%ck with a ccr strapped to your back 😎 I

I am currently SSI Advance Adventurer Diver (equivalent to PADI AOW) I am interesting to take a GUE Fundamental classes in the future to improve my own diving skills (i.e. triming, buoyancy and other dive skills), would like to know what the GUE system which I may be interested to be part of the GUE Diver, as well learning to dive in twin set and dry suit. However I am not sure where to start first. Do I have to start from double and drysuit primer first or I have to start with GUE Fundamentals as part of the compulsory course to get into GUE System? Thanks

Kann man den Bottom Timer als Sporttaucher als Tauchcomputer verwenden?
Er hat halt keine klassischen Computerfunktionen…
Man, stop making sense of using $120 gas on two OC 30 meters dives. It does NOT make sense at all even if you are rich! This video was made 2 years ago, now helium is even more expensive due to sanctions against Russia. The only sensible time to use 30/30 is as travel gas for deep trimix dives
The problem with rechargeable lithium ion batteries is imho not so much that they discharge over time. The real problem here is that you charge your backup light to 100% and then "never" use it, leading to the battery being stored for months or years at (almost) full charge. This is a bad situation for a li-ion battery and causes it to deteriorate.
I'd love to know what your dil stretching factor came out to be after a year
This video starts out by trying to prove that bar*liter does not exist or is a valid unit and tries to prove it by answering a different question: - What volume 200 bar in a 12 liter cylinder would expand to on the surface at 1 bar. In argumentation theory, this is called a fallacy. I am not impressed by this video or the creators understanding of basic physics.
what a great informative video, love it
Hmmm i use a 2 lb tail weight to be trim.. will this help? And the cutouts… what if i cutout my wing? To let thru the spg?
That might help. You can try, but maybe it doesn’t fit well if you cut it out yourself
1000 bucks ☠️
I’ve got a cave instructors old dui tls350. And I just got an aqualung fusion bullet yesterday for free from a guy so. I’m all about free and cheap. Especially on the life support stuff. I just have my guy rebuild it and it’s good as new
Rebreather diving is not about money it is about a life style
Absolutely!
So, after 8 months, what do you think of this light? How do you like the 150° angle? This should make you loose quite some lumens vs a light with a 120° angle I guess. I want a light mostly for ocean videos (macro or to give a bit of reflection to shoals of fish).
Still using it and still satisfied. Is a good light for the price
I want to buy one from Colombia
Sorry…can’t you buy it directly from them?
friend, do you recommend the page to buy from Colombia ❓️
Appart from the trim indicator why would anyone choose a halcyon computer and not a shearwater? How does halcyon justify its release?
It’s the controller for the rebreather😄😄
Hello！！I'm Ellie， remember that we have a cooperation on our heated clothes? I've reached out to you many times.
Yeah I wrote back to do. The plugs don’t fit and I’ve to get other plugs in order to use it 😄
@@DoktorBEN Thank you for your reply, we checked our email and didn't hear back from you, we think it may have accidentally gone into spam. Still very much looking forward to seeing your collaborative video, we're going into the holidays at the moment. We wish you a happy new year! Love your videos！！！！😄😆
Die Marine (German Navy) uses SPLIT FINS? SPLIIIIT FIIIIIINS?!!!!
Yes
I haven’t seen any specs on the Halcyon chest mount rebreather… what is the scrubber size? What is the target usage? Cave exploration? Redundant system? So many questions… ???
Leave me some content for my next videos 🤣🤣 But yeah…it can be used as travel rebreather, as exploration tool and and bailout rebreather. Scrubber size is a bit more than 2kg
Like most chest mounted rebreathers, back up, or accessory for sidemount and backmount.
Weiß man schon in welchem Preisrahmen sich der Rebi bewegen wird ??
Noch nicht definitiv…aber man kann davon ausgehen, dass es der Standardpreis von ca. 10000€ sein wird, schätze ich.
It's not about depth, it's about duration. It's about footprint. It's about waste. It's about flexibility. Sure, you can go deeper, longer, but that's a benefit that not many will be able to take advantage of. You could make your same argument about justifying drysuit vs. wetsuit. Just dive less and you don't need a dry suit right... It's nonsensical for anyone more serious about diving. If you're worried about the financial sensibility about diving, just don't dive. Also nonsensical.
Having only 1 seam is actually worse. As the SMB spends most of its time rolled up somewhere and getting bumped around, having a sturdy seam protects the fabric, as it's also already under stress because it's folded over. You're calling the seam the weak spot, but i'm pretty sure it's actually the opposite. And in the end, EVERYTHING is manufactured in China anyways, including the Halcyon one. It just depends on how much you're willing to pay for the little brand badge on there.
I don’t know for sure, where halcyon makes the SMB‘s but I guess you’re right
I had several takeaways from your video, but the main one is I need to take the GUE fundamentals course. Great videos, thank you for sharing your knowledge!
Good to hear that! 😂😂. So with whom are you gonna take it?
That’s a great question! I tried going to your website but it seems to be down. Are you stateside?
I’m redoing my page now. Sorry!
No problem! Looking forward to seeing it.
I think he is more flexible than me , do have stitches to help us that flexible challenged 😂😂😂😂😂😂😂😂😂😂
Ascent rate is no more than 9m per minute
Well…according to PADI it’s 18m/min max 😉
Why not simply use the rule of thirds and divide by 3? 1/3 Descent and explore 1/3 Go back and Ascent 1/3 safety stops and emergencies
Because in many cases, it’s too aggressive
I'm SSI instructor and TDI tec diver, I cant sell OWD course below 590 euro. If you will pay also for AWOD you will pay + 380 euro, and you will end up to the same price with the GUE Fundamentals......if you are a good instructor and you spend you time for the best training experience for your client, you can't sell your course with a lower price. I think you speak about quality philosophy that's normal to have in the diving industry, not only in GUE. Otherwise we will produce "victims" of the "low cost philosophy", as we can see in Red Sea and in other crowded dive sites.
I wish everyone would think like that.
No. Because it's a 3 modes light. So, it's annoying underwater.
Now that it's been around for a while are you going to revisit this as a recreational dive watch?
Yes, I’m going to do that
How about the blend 18/30
Why would you want to blend 18/30?
@@DoktorBEN its for my bottom gas.
@@DoktorBEN the point is, how do you count for 18% of o2. Can you explain? 32% EAN is 14% of pure o2. So how about tx18/30, tx7/72 or tx12/52. I just need to now how do you get 14% of number for mixing 32% EAN. Thank you
In general, the topoff proportion is the ratio of the nitrogen content in the desired to that of the topoff. For example, for a desired 18/30 (nitrogen=52%) and topping off with air (nitrogen=79%), the topoff proportion is T = 52/79 = 66%. In this case with only one source of helium, things are simple: you know the helium added must equal the desired: 30% helium. The oxygen is whatever is left over: with 30% helium and 66% topoff, you need 4% oxygen. In general, though, the required pure gas is the desired fraction minus the topoff*mix. In this case of air topoff (mix=21%), the oxygen proportion is O = 0.18 - 0.66*0.21 = 4% (as we saw before). Similar for helium. (The general approach is needed if you're topping off with trimix. Also, a negative answer means it's impossible with that topoff mix. For example, you can't get 18/30 by topping off with 32%.)
DLRG 😊
Not helpful. bullshit comparison. DOnt even understand
Why?
Funny, I never paid more than 1000 euro for any of my rebreathers... I have some Inspirations, rEvo (999 euro), Ray, RG-UF, and recently I bought Hollis explorer for just 299 euro :D You just need to know, how to service them, and that's not a problem for any technically capable guy (or girl)...
Then you’re just lucky. Even the filthiest cat litter box is usually a couple of thousand bucks😄
Can you comment on the best place to attach the battery on your harness? Next to the light canister or do carry the additional battery somewhere else? I’ve never tried having two side by side canisters myself. I haven’t seen it addressed in any GUE materials so I’m curious. Also the Santi canisters have a shorter EO cord than most light canister EO cords..what are your thoughts on that? Last question is a pitkin controller to adjust output to heating system and prolong run time..I’ve got one I picked up at the GUE conference auction but I haven’t used it as I’m still researching heating vests/gloves/additional battery from Santi but your opinion is important to me. Thanks!
Well…thanks for the question and valuing my opinion. I personally wear two canisters on the right side. Another option would be to use a canister with two cables. Both has advantages and disadvantages, but I like two canisters more. I personally do not use a controller, but I don’t see a real problem with it. It’s nice to be able to control the heating.
It's class for owd
This is brilliantly done, although it assumes the gas prices will stay fixed (which isn't likely). You can't know the future prices, but the break-even time should also decrease further as gas prices increase. Thanks for sharing.
And you can easily add an increasing factor for the gas price
wait... i cant just rent them?
You can. Depends on where you are
Hi! does it use 1/4 screw mount?
Yes, I guess it’s 1/4“
I've been using their batteries for years. Bought them in Singapore.
All the Agencies are nothing but a diving club. Their authority amounts to zero.
In the US, yeah. But the US is it not the world. Still, why do diving clubs need authority anyway?
Americans are sold on the Go Up Early training program primarily because they believe bigger is better, and that you get what you pay for, which in itself isn't true. GUE is what PADI was and still is. A marketing concept. Computers free up manpower and allows training and education via online. Your own videos are a testament.
Well…I disagree. First, because GUE is, unlike PADI, not a company. There’s no monetary goal behind it. Computers free man power. But their in-water teaching capacity is still rather limited.
