rebreather

Jack's Dive Locker did a great job supporting our recent trip to the Big Island. They had multiple Steel 23's for O2 and Dil (no waiting for fills), bailout bottles with rigging, and jugs of Sofnolime for about the same price as we pay on the mainland. David, the Retail Manager, was...

Hello, is anyone here willing to share their experience with the Fathoms MK III rebreather? I'm considering diving with a JJ or a Fathoms. Currently, I'm a bit more impressed with the Fathoms; I like the lack of electronics. I'm from Europe, and the device isn't really widespread here yet. I'd...

Hey all, Sharing my recent malfunction. We were about 165m into the sump and -8m depth. The oring of the omniswivel (ball swivel) connecting my left sidemount tank to my BOV decided to explode just when we were about to start the exploration of new cave passage. It was not the big oring...

I'm looking for a fully functional Drager rebreather available in California. The more complete, the better. I'm obviously not looking for something in the thousands of dollars or I would buy a new unit. Mostly would like something for backup/training/parts. Let me know what you have and how...

Had my Gemini for about 9 months now, recently completed MOD2. I've had a persistent issue with WOB when doing more than one dive on the same exhale scrubber. If I do, say, a 90 min dive on two fresh scrubbers, WOB is always great. Even at the end of a normal dive, it is still breathing...

Great condition. Some slight wear from use but otherwise great. $150 USD for set. Can ship immediately from Canada or from a US address every few weeks if you’re not in a rush. Buyer pays shipping.

Has anyone tried NRC D05R sensor for rebreather diving? I found their sensor is slightly cheaper than other Analytical Industrial and Vandagraph. I wonder if it has the same quality with them or not.

Hi my highest qualification is (soon to be) trimix extended range diver (45m, 1 deco gas) I am considering the AP inspiration EVP as my first rebreather and would appreciate insight from all of you as to why I should or should not get this particular unit. Why I want a rebreather Firstly the...

I have learned that the absorption of CO2 on a rebreather scrubber is imbalanced as there will always be some dead spaces that remain unreacted. I wonder why the scrubber works in that way?

hi i have an hammerhead my primary it's a dwtin computer (company seem close, but support continue). my secondary it's a Juergensen Marine rev c+ with hud diva. I search to replace my revc+, will need i think to replace diva hud too. Only the hud should be ok, but dtwin can power the diva...

Hi all! I'm here looking for advice on which rebreather to get! Living in Singapore, there is not much CCR diver presence and the one of the only means to get certified would be to cross the border to Malaysia (about 4 hrs) to get any form of technical diving training. The dive shop I'm...

New to the forms and trying to sell my Rebreather, haven’t dove for quite some time due to lifestyle changes. I’d figure I’d try to sell it here since trying to sell it on Facebook and craigslist in Hawaii is impossible. Looking to sell the Rebreather for $5000, OBO, Buyer pays for shipping...

Hey all, I'm a Senior Marine science student and diver out of Sydney AUS and have been deeply considering a rebreather at some point this year. However, most rebreather forums tend to focus on cave diving, while my diving is more like 2/3s shore dives to 18-20 meters and the other 1/3 of...

Parting with my Choptima as I'm getting out of tech diving for the time being. The unit has been loved and well taken care of, always rinsed thoroughly with steramine and fresh water after every dive. It has never seen salt water. There are approximately 40 hours on the unit and it was purchased...

Saw the post this morning on Halcyon's Instagram page. Looks like they are teasing a new rebreather design / product line. Just from the picture alone it looks like a chest-mount design (which, of course, wouldn't shock anyone given how many new chest-mount models have entered the market...

It is with a heavy heart that I post this, but I don’t dive it enough. I have a dive ready CCR Liberty that I purchased it in 2018. The unit is in perfect condition. The entire unit was service in March of 2023, and the head was just re serviced in August of 2023. The unit had around 80 hours...
