Open Circuit Vs Rebreather is actually a very interesting topic and is probably one of the biggest leaps since going from snorkelling to scuba diving. First of all, I need to break down some of the gear and terminology because I’ll be rattling off acronyms throughout this video and if you’re watching this then you probably don’t know the difference between an SCR and a CCR.

No.1 reason to use ccr is that you look like the coolest diver in the world
True story
Straight out of a video game
Another advantage of rebreather is the quiet. On dives with lots of marine life, you can get p close and personal with them without scaring them off with the deafening scuba noise. You also get to hear the reef. The sound of parrot fish chewing on coral. The crackling of the reef itself. So many sounds you just can't hear on scuba.
I've been diving closed circuit rebreathers for 20 years now and I will disagree on one point. I use my rebreathers on every dive. I accept there are differing opinions on this matter especially within the rebreather community but this is my opinion. I do deep tecnical dives, cave dives and extended decompression dives. I also do recreational dives within decompression limits and I use my rebreathers for all of them. Rebreathers are fundamentally and functionally completely different from open circuit in almost every aspect of how you plan for and execute a dive. Why would I choose to change every aspect of my equipment and emergency procedures only on the occasion that I am doing an especially dangerous dive?? By keeping my equipment and bailout sequence consistent and practicing emergency drills regularly I can be confident that my training and experience will give me the best chance of surviving an emergency that I can hope for. I don't want to be that diver who dusts off his rebreather every two months and tries to remember how different it is from what he is "used to" as he is descending 100 meters down to explore a shipwreck.
I met once a CCR diver who called rebreathers "the most expensive suicide machines'. he liked his CCR though :)
probably was a YBOD.
CCRs aren’t dangerous, but the people that operate them may be!
@@nickbrooker1411 true, but they can kill you in new and more ways =)
My crotch rocket has you beat on the most expensive suicide machines................trust me. Is Anyone in the market for a motorcycle that can hit 200 miles per hour in less than 20 seconds.
@Pagani Zonda suppose your right
I love my ccr, I consider the whole unit(including bailout/BO CCR) much safer than open circuit single or twins. Yes there are downsides, and risks, but with proper preparation and risk mitigation you can get so much more out of your dives.
I agree with this. People say twin engine airplanes are twice as likely to have an engine failure. Sure, but with risk mitigation you'll be glad you had it.
@@kasken719 I jump out of planes all the time, have I had pulled my reserve? Yes. But that's why it's there, if you have tools for risk mitigation then claiming to not have them or trust them or rely on them can't be an excuse that someone puts on others, I'll always allow personal trust and fear sure, but not mongering.
@@Mrich775 I'm not sure you understand what I was saying. I agree what what you say. Not "mongering". Not exactly sure how you came to that conclusion. Having and trusting your secondary or safety equipment is important. I'm a professional Pilot. That's literally all we train for. I can see how CCR has its risks but so does Open Circuit. The point is, as long as someone is comfortable with the risk then have at it.
You're comfortable with your equipment and backup equipment while diving.that's actually pretty awesome. I'm not. I did it one time to say I did but it's just not for me. That doesn't make me wrong or right. If someone feels safer and more comfortable in CCR or cave diving, etc then by all means dive that way.
@@kasken719 I was simply agreeing but ok then.
When the term CCR is mentioned, am I the only one who thinks about Proud Mary.........Bad Moon Rising......Who’ll Stop the Rain..........ya maybe I’m on my own here? 🥺 😳
Let's be profecinoal and talk about..... Mark's vest. What is that for?
Yechiel Rechtschaffen: Does it perhaps convert to a BCD 007 gadget style when you remove the handkerchief?
Bottom button of your waist coat is undone, a nod to correct dress, or excess girth? 😁
The earth is one large rebreather
Thanks for the info! Would also like to know the longevity of the gear (taking into account avg wear & tear). What are maintenance costs? Setup time?
I've been really looking into it but the cost is holding me back for now. 🥺 First saving up for a drysuit, then a cave course.
Super excited for this subject!
Guys I love your rebreather videos! I think it's so great to get more people diving CCRs. And really I've learned that most people don't becuase of the price or they are just nervous.
Once again. Thank you
Oh and one correction you ALWAYS HAVE a O/C bailout bottle. You never dive CCRs with out one.
You can now get rebreathers that can be worn like sidemounts. Much lighter and more practical. I would like to try one but lm a little worried about their safety record
Stephen S2r Then go with an mCCR like the KISS Sidewinder. Barely any electronics since manual. The KISS has double scrubbers which means flooding one isn't the end of the world. Very good safety record which is why it's popular with cave divers.
@@Yggdrasil42 Many thanks for your recommendations. I'll look into them
I run a kiss sidekick for a bailout breather since I can convert it between scr and ccr, sidemount units are great, and if you stick with a commercial product vs homebuilt or modified you should be fine. Kiss as well as liberty have great sidemount units.
And on a more serious note, you may have convinced me to start learning rebreather
Our plan is working!!
Very informative! Thank you!
Used CCR in the Navy at Dive School. You need to get into some areas without being detected. I loved it and want to get one for sport diving. I will probably need to take the classes for mixed gas and Re-breathers as Most classes do not recognize Navy training. Plus I have not been doing CCR for over 30 years so there is probably some changes in things that I learned.
Dale Johnson i retake interest on scubas after take my diving course on 1995 ,it’s like how to learn to go on bike, a little refresh from a scuba diving school is a nice opportunity Too. I switch from ara to rebreather Too and i am impatient to learn a technical diving philosophy
They dont recognize Navy dive training? I would have though Navy divers would be the best divers
@@chang.stanley My experience has been that if the military institution does not have an arrangement with a certifying civilian body to make transferable maritime military skills (diving, Coxswain, Captaincy, navigation) recognized by civilian entities then you will have to get those civilian qualifications. What is often seen by civilian certification bodies is that competent mariners/divers will nail the civilian certifications.
very well done
I used CCR for many years and I came back to OC. The reason is simple it is like driving a Formula 1 race car in London. ;-)
I was scheduled to to board the conception tonight and depart at 4 am for a dive trip with the Marin dive shop.
I just got quoted $1,900 for service of my rEvo CCR at the rEvo factory. Just warning you about that expense.
Good videos lads as always!!!
Thank you for the advice on tec bcds...... I want to see what Mares is going to do with their horizon scr model.
SCR has all the disadvantages of OC and none of the advantages of CCR.
Can't take part in the poll. Haven't had the opportunity to try CCR yet. :( Sounds awesome though! I know a guy who dives one and he says he'll never go back to OC. lol Is there such a thing as a try-dive for CCR? I wouldn't mind doing that!
Chris Carleton yes there is I did one
Chris Carleton Yes, but there's lots of variation in rebreathers (which is why each one has its own certification) so make sure to research and try multiple if you're interested.
Good choice on being sensitive to the recent dive boat tragedy RIP.
But in the near future please do the originally scheduled video because the purpose of which is to learn and live.
I would love to try it, but I don’t know of any dive shops (Northern California) that offer it. Got any suggestions? Willing to travel anywhere.
What's the advantage of scr over ccr? Didn't mares launch a new one a few months back?
A liberty rebreather, is gonna cost you about 10 grand. But they are very safe and bad ass.
how does a bcd work with rebreathers?
do you need a cylinder just for bouyancy?
Depending on setup, but usually you use the Diluent gas
should work of your diluent id guess but not sure
Waleed Zaghloul either use Dil cyl or added extra mini cyl, but for dry suits we tend to plug direct into our bailout cylinders (large side slung)
Nick Brooker Perhaps I miss read it, but did you just say you use bailout gas fot suit inflation?
Björn Jakobsson yes, from the first stage on my ali 80 i have a hose straight to my BOV and another hose direct to my dry suit feed....saves your Dil for it’s intended purpose!
Only have 43 dives under my belt but I’ve jumped into this hobby both feet in I ditched my jacket style for a utilitarian backplate and wing bought a top of the line dry suit but now I want to learn rebreathers I’m looking at buying my instructors drager dolphin scr any suggestions? I’m very comfortable in the water but a single 80 only last me one hour underwater and I ain’t slinging no doubles f that I’m not a body builder I’m a twiggy little guy I know scr and rebreathers aren’t light but if I’m gonna lug around some heavy sh*t I’m not carry 2 doubles 😂
Here I am 3 years later over 1000 dives later i Own an rd1 ccr and I love it so much
I'm certified on both open and clossed circuit. With a NAUI Evolution cert.
How does it work man?
I'm getting my cert in Open Scuba/Nitrox, do I have to wait a while?
@@jaysaini955 it is expensive and you need to put in much time in the water to build up your muscle memory in case you get into trouble. I had to bail out once when my loop flooded and I got a slug of liquid Acid in my mouth instead of fresh purified air. I assended slowely and started vomiting at the surface. It took all day before the swelling in my throat went down enough to drink a cold beer at the Catalina bar.
Any recommend units?
JJ CCR all the way ;)
Qiukai Pan AP Inspiration.....pedigree and excellent track record! Most rebreathers are modelled on these!
KISS Sidewinder; Liberty
2.05 you say you are not breathing under pressure like with open circuit, explain please how this is possible?
I recon he means that youre not breathing from a pressurised unit
he's talking about an SCR. Different beast. SCR has all the disadvantages of OC and none of the advantages of CCR.
Happy with your decision not to carry through with the “10 ways to die” Great decision!
i have heard that Rebreather are more dangerous? or do i confuse it something else
More complexity + Humans = More danger.
I have heard that rebreathers are quite scary, or they have a really short window for error
they are unforgiving, but not scary. The window for error is not short though, although depends on the error. Training covers all this.
Who told you this? OC has a short window for error. Critical gas failure and you have a few seconds to respond. On a CCR, if I loose all my O2, or all my diluent, I can still solve my issue in minutes before getting too low on O2. In these few minutes, I just plug in my bailout and manually feed from there and I can use my 80cf bailout 3 or 4 times as long as a backmount 12L cylinder. With proper traning, a CCR is much safer than OC
Björn Jakobsson well i am a total noob at all of this, since I have not even get into any training at all but i will in the next two months, the thing that kind of scares me is the risk of hypercapnia that makes you lost the ability to think straight and make the right decisions and that its not easy to spot the firsts symptoms of it, ill defo get into it, im just researching on what should I be cautious with
@@dante316a Hypercapnia is a bigger issue on CCR for sure but as always, if you dive within your limits and do not push it, and have correct training, you are not really in the risk zone. You do have a bail out that (usually) helps if you start to feel the symptoms, and you should, if not during training, so do it after, try to get hypercapnia under safe circumstances with a friend nearby just to feel it. I did do by going to nearest quarry, picked up a stone and started jumping around. That will for sure do it!
Ive watched 3 of your videos about rebreathers. WITHOUT YOU ACTUALLY SHOWING ONE.
Im a newly certified Open Water Diver with only 13 verified dives so.. AllI care to know is which will preserve or increase my changes to 'not die'! ..thats all.
Congrats on your OWD. Knowing your limits, having a responsible buddy and properly maintained gear will, not the type of the circuit :)
Rebreathers can add task loading which can increase risk, take your time, build your hours, then look at ccr down the road.
drunkerjack holds the key !
Rebreathers are awesome and unmatched in what they offer. But if sensors get "confused" it will actively try to kill you with every breath without you even knowing it until it's too late.
Open circuit is just a #flappysnaghazard
OC 4 LIFE
I'm wary of rebreathers following the death of Rob Stewart.
@@zilla5g Yes, you're probably correct. Sotis seemed reckless. www.flkeysnews.com/news/local/article141263723.html
Rebreathers always. But unfortunately every major diving company is spineless and won't sell front mounted rebreathers at a reasonable price..
Just go with a back mount CCR and live a happy life :)
No. I have a choice. The major diving company need a too sell a inexpensive front mounted rebreather ....
Dive rite is releasing a chest mount optima very soon. However no ccr will be inexpensive.
I see a bad moon rising... no just me
Sorry.
