rebreather

Selling a Hollis Prism2 rebreather. Unit purchased in 2019 from an owner of a shop where it had been used as a try diving unit with only 8 hours on it from ~2016. I upgraded the head in 2021 with a Petrel 2 controller and new HUD. Since then I have only dove it twice. I added an extra 5-pin...

Might be selling my Meg 15, almost all parts are brand new. Putting feelers out there first. $5,000

I ran into some issues with wanting to move where my Nerd 2 was positioned relative to my eye, while still using the adjustable Revo mount. I created a 3d model of the original part then created 2 different sized extensions that add 10mm or 20mm to the original part. It does require a bit of...

I’ve noticed that some divers for especially deep or technical diving are choosing to off board diluent in their bailout cylinders. This is more or less how the whole sidewinder/Gemini community does it in my understanding. My question for anyone who does this is, how do you choose the PO2 of...

Hi there, are there any Meg Ledge charters that organize trips for CC divers? From what I understand, these are typically 30m/100ft dives that would benefit greatly from a rebreather to increase bottom time and decrease deco time. After some time spent on Google, I have not been able to find any...

Hello to all. I'm trying to update a posedion MKVI for months but I got zero progress. I think I have tried all the things I can think of and got nowhere. I wonder about your thoughts and advice about this. Here is the story: Poseidon MKVI is no longer produced and not getting updates and...

To preface, I am a relatively new rebreather diver (only ~20 hours on the unit). On three distinct dives, with all three being more strenuous or task-intensive, I’ve had an issue where my nose will begin to “free flow” or “vent” on inhalation. My first reaction was to reduce loop volume...

I wonder if it’s common practice to replace the O2 sensor cables/ harness when replacing the sensors every year. This is the JJ philosophy whose sensors already include the wiring. According to some the cables are prone to oxidation and hence may cause sensor failure even if the sensor itself is...

Would like to get the experts opinion on which options to get with a new Optima CM. Here are the ones I identified so far: Nerd 2 as controller paired with HUD — no cables going to the wrist XT1 first stage — rotating turret Upgrade the ADV/MAV to a high flow quick disconnect QC-6 fitting...

Very curious which rebreathers divers in south Florida are using. I'm sure northern Florida is dominated by cavers, but what about here in the south? Would love to hear not just the make/model, but also the type of diving you use it for, why you initially chose it, what features you like/don't...

As the title states, I'm interested in learning about local community/group for CCR divers. I'm very interested in converting, but need to find buddies, information, etc. I mostly dive out of Pompano. I'm not even sure where to start. I'd like to know what units others dive in the area. I see...

For sale is a KISS Sport rebreather with the stainless steel box (vs the Aluminum) and a three cell (PSR-11-39-MD) sensor pod with a single fischer cable from Tecme. I changed out the original KISS BOV for a DSV (can't remember the brand). Also added a SS handle/ pod protector to the frame...
