Where should I start to approach the rebreather world

struggling with trim in a 3mm

Couple dirty looks at Ginne but you can learn to dive one of these in a cave if thats what you got to dive with. Draker can also cherry pick a few moments of brilliance

(which, apparently, EVERYONE else except Poseidon agrees is a good idea).

The fact that the patent on the 2 physical, one virtual, constantly calibrated and compared method of sensor validation belongs to Poseidon (via Bill Stone and co and the various Cis-Lunar models since the 80's) may also have something to do with it.

One interpretation could be that voting logic is the next best alternative.....

How did you "paint" the Revo cover.

Appalling trim in those photos. You must have drowned many times.

Do please keep those excellent photos coming. At the end of this season we need inspiring photos so we can all live the dream albeit vicariously.

One problem from mainly diving solo and in crap visibility is there’s few photos to look back to

Truck bed liner built up and the epoxy paint pro stuff not rattle cans.

Nice.

So you literally masked off the bottom and the round disk in the middle then sprayed it?

That's how I did mine. But, with Plasti-dip rattle can sprayed right onto the cover.

I'll give you that one - to the extent that "everyone" MAY feel that way.

Personally, I watched the presentation from the scientist/engineer/whatever at Poseidon that explained why their system is better. In short, I majored in Applied Mathematics in college. I feel like I have some qualifications to form my own opinion on what he presented - and I do not believe that the Poseidon system is as good as a 3-cell system with voting logic that is used and maintained as intended. IIRC, the Poseidon guy even acknowledged that in his presentation. His basis for saying the Poseidon system is better was based on a presumption that many people do not change their sensors as often as they should or something like that.

Don't hold me to the details of all that. It's been a while since I watched the presentation. The point is only that I personally do not think it is as good. But, it's just an opinion.

First of all we need to sort things out. Rebreather diving has been around since 1800. Mostly done by the military divers and with machines that costs fortunes to buy and maintain. The thing with Poseidon Rebreather, is that it was the first aim at the recreational market. It was the big revolution in diving, since the recreational market is 10000 times bigger than the technical side. Together with old school rebreather inventor/diver they came up with the MKVI 2009. It was not a rebreather and will never be one. The difference lays in the monitoring system of the diver. A system for a recreational diver has to be so much more sophisticated than a rebreather monitoring system. A "normal" rebreather can kill you in 2 min if you don't know what your are doing and can respond to different types of errors and changes inside the system. The Poseidon system is monitoring you as a diver and will tap you on the shoulder when something is about to happen. It look 15min ahead in time and tries to predict what will happen. It will then ask you to do something about this. This approach is unique. Other manufactures makes rebreathers. They tell the diver to get training and experience. Even experts do mistakes. On a Poseidon it is more likely to get information about what is going on and the being able to respond correctly. The machine is a little bit more advanced and if you don't look after your machine or have been taught the knowledge about small-little-things-that-can-go-wrong-during-startup then you will hate the machine. A good instructor will teach you all these skills and know hows. A rebreather is a simple construction of lungs, gas, sorb, hoses. This way you can always override thing and get into the water with a non working machine. Poseidon has another approach. If something is wrong on the machine, you wont get it into the water. However, it has a fail safe function. Even if you jump into the water without starting it up, it will start up and keep you alive until you are above water again. A feature no other machine can perform. The Poseidon is the safest machine in the world.

The thing for beginners are to get a SE7EN Sport. A basic startup version of Poseidons life supporting machine. It is priced very aggressive and is also upgradeable to a full Trimix +150m beast. Your choice.

If you are sick n tired of filling your tanks and looking at the manometer all the time, then this is for you. Diving with a Poseidon is a joy. You can stay down 3-4 hours with 3lit oxygen, 3lit air and 1 cartridge of sorb material.

Start off by booking a try dive with an instructor. Do an Open Water + Advanced course on the machine. This will make it possible for you to get another certificate (yeeeeaahh!) and also being able to rent a machine to begin with.

It is just such a shame that the poseidon will lock you out of you personally owned unit
until you send it to a dealer for servicing and unlocking even if servicing is not required
