I am still skeptical about getting a rebreather. The cost is the big negative factor for me. You also mentioned a good point about having buddies that may not have one. They do still them fascinating and I wonder if in future they will be the norm even for a newbie.

If you aren't tech diving, the case for going rebreather is very very slim.
@Teampegleg Жыл бұрын
@S. M. In OW Tech depth is generally the prime factor as the cost of trimix easily offsets sorb. Which makes the additional cost and risk worth it. You get the most benefit in overhead diving like wreck and cave. In particular the cave environment where you don't have the time constraints or extreme depths. So you can spend hours in the cave, for example a friend would wake up early and do a 3 hour cave dive a couple of times a week.

Cool video, love your videos. I got my Rebreather in may 2022. A JJ-CCR . A big investment, but o boy how cool to dive with . You should have mentioned as number 4 in your list of benefits : logistics. Here in Norway we mostly dive on our own and in dive clubs, newer or rarely use of a dive centre. So when we travel in Norway we bringing a couple of oxygen tanks, sorbs, and some diluent tanks and we are self supporting our diving gas without bringing a compressor for a week of diving. When are blue world visiting Norway? We have some very cool dive sites here.

Very well put Jonathan. I think there is a misunderstanding about the universality of rebreathers that you have explained really well. Rebreathers, like OC gear, are just "tools for the job." If I'm diving deep, or in caves, sure, rebreathers are great (though sidemount is another great way of diving in those situations, to a certain degree.) But if I'm just going for an hour shallow reef dive, there's no real benefit to a rebreather, either CCR or SCR - easier to just grab a regulator, mask, fins, and go. Also, interested divers should understand, most accidents or casualties on rebreathers occur at or near the surface. So really proper training, like you (we) got from Edd, is just a beginning. You cannot be complacent at all on a rebreather. It is not as forgiving as O/C, although if properly trained and prepared, it can be safer.

I would have add in your list of advantages the fact that you have way more problems solving options with a rebreather then what you have with an open circuit rig ex(bailing out of the loop to fix it, passing on semi open , or just simply bailing out o a completly redundant second loop , diluant flush etc), its a major perk in my opinion

Some other cons are: If you get disorientated you can’t see the direction of your bubbles. You’d have to pay close attention to MODs for oxygen toxicity as well and more to the point about being the only diver on the boat with one is that you can’t stay down any longer anyway because the time is always limited and because the DMs want you to stay as a group you can’t really go super deep or they pick a dive site that isn’t deep anyway so unless you are going on a purpose trip and plan it ahead of time with the boat and go through advance prep and notify them etc it isn’t going to be that advantageous which also really makes this kind of another con in that you have to do a ton of extra planning to pull it off for it to count. Lastly when you travel with your tank and have to take the valve off as he mentioned you then can run into issues where the tank and valve need to be serviced/re-O2 cleaned just to be able to fill it again at your destination and that can not only take time and be difficult to get done but it’s yet another added cost. I’d certainly be interested to try one of these in the pool but don’t think I’ll ever get into them. Lots of people have died on these and you need a lot of focus and attention. The simplest thing could hurt or kill you in general while diving OC but this exponentially raises the bar and risk level

Rebreathers have about ten times the accident rate of open circuit scuba. Yet among the military, rebreathers have about 1/10 the accident rate. Why the difference? It seems to be that military divers are more careful about checklists with assembly. Accidents with rebreathers almost never turn out to be issues with the rebreather itself, but with mistakes made by the diver using it.

I'd love to see the effects of Propranolol on extending oxygen during a dive. It blocks adrenaline from sticking to your muscles and prevents the sympathetic effects of the fight or flight response. It's used as a performance enhancing drug in sports like shooting, public speaking, and singing. It keeps your body relaxed even if your mind is freaking out. I've seen studies that seem to indicate that since it temporarily reduces metabolic activity in the body, it can help minimize the effects of decompression sickness. Less oxygen consumed, less co2 generated, less nitrogen entering the muscle tissues. I've been prescribed it for anxiety, but i'm interested in just trying it the next time I'm out scuba diving to see how much longer i can make a tank of air last for. Also to clarify, it's a beta blocker it's not a gaba receptor agonist like a muscle relaxer is, it doesn't induce intoxication or anything or force muscle relaxation, it just prevents adrenaline from taking over your body which increases respiratory rate

Fascinating machines really. I have always wanted to enjoy long hours under water, huge advantage of rebreathers. But as you mention in your comments below OC is much better and logical choice if you dive shallow. For me the main problem is the high price of the equipment, maintenance and travel difficulties. Seems like is suitable for well financed expeditions (like your documentaries Jonathan), or being rich person to afford or if you live by the sea and dive every week... and you're willing to undertake hours of cleaning and maintenance each time.

All kiss are manual mecanical , it means you manually operate the valves , meaning that there is no computer that will monitor your set point po2 for you and automatically fire the needle valves for you , it requires more knowledge to operate in my opinion then lets say , an inspiration silent breather rebreather , its also more versatile for the cave aplication since the depths are not always constents lots of up and downs so you want to be able to adjust your loop blends by yourself but for other aplications like really really deep dives (more than 300 ft aprox) , the mecanical rebreather is not an option anymore

@Yggdrasil42 Жыл бұрын
Not manual but mechanical. There's a constant flow of oxygen into the loop (tuned to your body's metabolism) so you only need to occasionally add oxygen yourself. Maybe once in 15 minutes. It's not comparable to controlling a JJ manually (if the electronics are broken) which would require constant manual intervention. The Kiss is not yet CE certified but they're currently working on that. Probably late this year. Many cave divers prefer the Kiss over the JJ for two reasons. One, It's very streamlined, both the rebreather itself and the sidemount tanks you use for bailout/diluent. Two, the simplicity means that even if it breaks it's easy to troubleshoot and control manually so you can safely exit the cave. It's simplicity comes from the fact that's it's mechanical. No solenoid, barely any electronics.
