AP have the best rebreather manual imho. Attached shows the considerations they have for scrubber duration.

I am an absolute rookie. Page 43 of the AP xpd manual has a warning on repetitive dives on the same scrubber. https://johnclarkeonline.com/2013/11/11/how-does-your-rebreather-scrubber-handle-the-deep/ This is a link explaining the concept. AP have their own Ansti machine to test these...

Split counterlungs are used when there are two counterlungs, one for the inhaled gas and one for the exhaled gas. They are flexible bags and must have enough volume to contain a full inhalation or exhalation. They can be mounted on the front, back or over the shoulders of the diver, their...

Hi just wondering how people are going with their seaskin suits? Are they holding up or turning into tea bags? Looking at a seaskin or just spending the money and getting a Santi elite (don’t know how much better it can be 🤷‍♀️)

I own a 2020 vision with the newer head (electronics seperate, cheap to repair/replace though I have never had a problem) Said this many times but the main benefit to AP to me is the direct to market parts, no middle man. If you service your own gear AP is fantastic. The AP regs are great and...

I dive a AP2020. One thing not mentioned and it’s one of the big benefits for me is that AP will deal directly to you. Any parts, spares, upgrades and even a new rebreather without going through a shop or instructor (I am not a fan of the middle man) this might drive people away from...

AP has a audible alarm “buzzer” which is really loud underwater liberty rebreathers have vibration alarms which are apparently really hard to miss only ones I could think of. But you should never need them if you are monitoring your rebreather like you where instructed in training.

Yes the philosophy is different and the design is different hence my point the JJ is not a AP 2.0, I like the JJ and nearly got one but got a DPV instead Its made out of a metal that corrodes and the anodizing that is put on to prevent it also suffers in salt water and heat. Flood the unit and...

I don't understand that more evolved description... AP has a scrubber life monitor, C02 sensor, one of the clearest displays on the market with hall sensors not piezo on the handset. fibre optic hud that wont ever flood like the shearwater. dual controllers in the head. Its own regulators, bov...

Well you can alway make another one! Well done. Maybe work on Delrin trigger rod. Saw a post on a Facebook group. Gets rid of possible corrosion issues

Super cool to see, I need a short body for my cuda for boat diving . You where spot on in other thread. Absolutely no reason to reinforce 6mm alloy.

Will you be adding any ribbing or welding in support? I’m not sure if the pirhana has any or not. Seems like these bodies are made out of 200mm diameter 5mm thick pipe and then just lathed. The Sierra was left 5mm the whole way (like the pirhana?) cool project looking forward to the finished...

Awesome work on the tube and battery holder. Would be good to see when you’ve got it on the lathe and machining the sealing surface! I have chemical stripped the powdercoating. Interesting it didn’t touch the alodine underneath. Sanded and then scoth brite the alodine off to get the clean...

it was a custom battery, huge thing still trying to work out the details with that but is 63 amp hour apparently. Very nice on making the replacement tube, looks really good. I’m looking at glass beeding my cuda body/tail, getting the sealing lip tidied up (will help maintain clearance with...

I ended up getting a cuda 650 with a lithium battery. Thanks for the advice.

I boat dive (in Perth) of a 21ft boat. I put my bailout in the water first. I clip it on to a piece of rope that's attached to a boat and also a float. Rollback holding mask and dsv then clip on in the water. Just an idea as it might allow you to keep the loop from getting water in it. I...

any update on the neoprene suit?

Got a link?

What is complicated about the xccr? From comparing specs and engineering. objectively Its a better generation of the megalodon rebreather that doesnt rust (delrin can vs alloy), better ADV, bayonet head and removable cell holder, one of the best bov's, c02 sensor, hp sensors in the head.

Hi, I am after a cuda 650, in decent condition and not flooded. Not too worried about the battery condition. Let me know what you have. Cheers
