There have been plenty of "how to choose a rebreather" or "help me choose my first rebreather" type threads over the years, with a couple of great discussions happening recently. So I decided to be completely redundant and start yet another one with what I've deemed some of the most important...

After telling myself I'd never switch to CCR, I'm beginning to hear the siren call and am going to do a try-dive on a Sidewinder next Spring in Tulum... Until then, do any of you have recommend/favorite books on the subject to keep me busy until then? Although I have a couple of units that...

The Liberty is touted as one of the most fault-tolerant rebreathers on the market. Redundancies abound. It’ll come with some accessories (I purchased protective custom sleeves for the exposed rubber breathing loop, for example), soft goods, hose caps for storage, etc. All you’ll just need is...

MAKE OFFER! You tell me what you'll buy my meticulously maintained, well loved rebreather for? Selling my Shoulder Mount Counter Lung O2ptima, shearwater electronics SS stand, packable and cartridge canisters. Bayonet style DSV. Large counter lungs. Brand new never wet Kydex cover. 4L steel O2...

We asked some of our friends, associates, and followers on social media to ask us questions about rebreathers we could include in an upcoming video. Here is Jon and my take on the 'Dark Art' for both recreational and technical divers

Full disclosure- I know next to nothing about CCRs but I want to keep my options open to learn and use other equipment in the future. I have been looking at the Teric and Perdix computers and when they list features about operating modes, I have seen comments such as "supports CCR bail out"...

So I took my new Blacktip out for its first run Saturday 3/7/2020 at a dive site with current strong enough to keep me in an absolute stall in gear 3. I was kitted in a rebreather (rEvo CCR) with a AL40 bailout. I have owned a Sierra and was diving with two buddies, one had a Sierra with the PTB...

I’ve had the pleasure of joining Bruces’ wreck diving trips out of Sami San before and was looking forward to getting out to sea for 5 days - without wifi connection! This alone would have tempted me, also on offer was the chance to dive two of my favorite shipwrecks - the Seacrest and the...

Would love to hear the pros and cons of the shrimp bov and divesoft bov. -What has your experience been like? -What do you like or dislike about the bov you are currently using? -Can it be user serviced? Are parts easy to find? For the Divesoft, if you have the BOV + ADV version, I'd love to...

I will be travelling with my JJ for the first time soon. As this is my first time and I am still relatively new to rebreather diving, I am not sure what spares and bits to carry. Does anyone have a list of spares that they usually carry? Also any particular things which you have found useful...

I have noticed that when I am holding a stop at a fixed depth, the loop volume steadily slowly increases until I have to vent some gas out. I cannot understand why this is the case - the electronic system is adding in enough oxygen such that it replaces the oxygen that i have metabolised. So...

I have decided that it is time to switch to CC diving and i am currently looking into what unit to get. I am mostly inclined towards the JJ because it gets solid reviews and all my rebreather buddies dive JJs. My first instinct was to buy the unit new to avoid any unnecessary issues when...

Hello, I'm selling my O2PTIMA. It has not been in the water since it's last service in 2015 by Dive Rite at the Flordia HQ. It is fully functional and the unit is unlocked. ( if you buy this unit you assume all responsibility for appropriate training) . The reason it has not been dove since...

Hi Team! I’m wondering if anyone has any leads on instructors/shops that teach the PADI Tec 60 CCR course on the Hollis Prism 2 in the Asia/Pacific region (specific enough...?:D). Preferably not in the US, so closer to Australia. I’ve done some googling and not having much luck. I’ve also...
