This is an ad.

Those who want to be offended, look away now!

My review of the Discovery will be available in hard copy form in Diver and DYK any day now.


Thank you for not being offended.

Already got mine. Anyone else think Jingle is the spit of John Peel?

How'd it compare with Rich's review?

Any chance of a soft copy, I don't bother with the dive mags.

I dont get the point of a CCR for <40m no deco dives, but read it anyway.

Chalk and Cheese.

Rich clearly indicated its limitations and errors that caused him most frustrations. To be fair, Rich's review was clearly aimed at the technically competant diver and lets face it, the majority of Diver readers are unlikely to be riveted by the speil on how cell validation is determined and what error code means what. I am surprised JB didnt get the plethora of 'no dive' errors.
JB's article was fairly comprehensive and when you look at how much real estate it covered in the mag, it covered it quite well indeed. I also think you have to be careful who writes what and where it is written. I remember one article on a Ferrari that the author made a big thing over how crap the clutch was. If you drive a Punto all year, then your never going to get it. They are more interested in the 0-60 and the price tag than a thorough critique.
You have to write to your audience, I suspect if JB had written it for RBW or YD in this section, it would have been very different.

In the same way you justify a Porsche Cayenne. By walking into the Range Rover dealer and asking "hav'nt you got anything more expensive?"
Justification is in the eye of the user.

It is NOT a techical diving CCR. I have been to Cocos five times. Once I went with OC but never again. I otherwise used CCR but never went deeper than 40m. I got really close to the hammerheads with my camera by lying near a cleaning station and keeping still. You can't get good pictures if you are more than one metre away. It was never conceived for technical diving. If you look at Wetpixel you will notice many people are prepared to spend upwards of £6000 on a camera system so the price may not be a deterent.
Wrecks are being destroyed by the oxygen in exhaled bubbles from OC. If you want good pictures inside a wreck, CCR is the way to go because no bubbles dislodge the crap from above.
This is the sort of diving this Poseidon CCR is intended for. Let's wait and see if it takes off.

In diving, we progress to deeper and more challenging dives. To do this, we make sure we use the right tool for the job. Rebreathers are just a tool to allow us to do the job in the best way possible.
The issue is whether it is the best tool. We tend to replace one set of risks with another.

We dive air because we want to enjoy the underwater world. as we progres and want to stay in that world longer, we start mixing gases to help with that task.
So we use nitrox. We offset the extended time and reduced decompression with the risks of oxygen toxicity and reduceddepth capability.
As we wan to go deeper, we use trimix. Reducing the narcosis but adding to decompression and ascent/decent rate limitations.
As we go deeper for longer, we use rebreathers. Offsetting the limited gas and gas management limitations of open circuit with the advantaged of rebreathers, but add to the risks with complexity and consequences of unpredicted failure.
Right tool for the right job. If you dont need a rebreather, dont use one. Its not worth it, its not easy and its not cheap.

The amount of people that you discribe are few and I would not presume to debate their personal choice of risk vs. picture, but what I will debate is the other 95%+ of potential buyers who like to wear the emporers new clothes.

I came to diving late after years of competition paragliding. The wings we would fly at competitive level were often straight from the drawing board with only a few flights by a test pilot. Often they were mind numbingly dangerous and quit a few pilots were killed or crippled. But they won competitions and were really exciting to fly! However that was the nature of the sport and the hotships that we competed on were eventually sorted out and good up-and-coming pilots would rush to buy them and fly them. I reckon that diving is very similar and that we like to think we are progressing and benefiting from the technology that the pros are currently using. Maybe it is often the Emperors New Clothes but it's progress and it's a bugger to stop and people will get hurt or worse; though I'd put money on the fact that eventually rebreathers will be the norm.

When I go on a liveaboard outside of Egypt I find that nearly every passenger has an advanced DSLR camera outfit and wants to get close to the wildlife. Maybe the average British diver would not be interested but on a world scale most of the blue stuff is outside of UK waters. I agree that members of this site would probably not be interested in either DSLRs or this CCR.

Maybe 'divetheworld' is a misnomer.

 

[divetheworld]

And do you measure others CCR competance against your own experiences too?

Thats the problem with assumptions. Should we start the pissing contest now?

 

[BJ]

You are making the assumption that no-one wants a CCR for dives shallower than 40m and I am simply pointing at that a great many people do.

 

[divetheworld]

then try to refrain from childish comments and use reasoned argument.

Gentlemen, enhance your calm!!!

More generally and FWIW (not much really, but anyway...), I have learned to use a CCR for no-deco, sub 40m dives (partially based on comments/thoughts from [email protected] peeps at the last NEC diveshow incidentally!) and was interested in reading about this new machine. I completed Mod 1 with a view to be able to use the Evolution and see what it added to my diving - we can all read what it is supposed to be able to add but it's another matter to actually "feel" it. But also I could see what else it might offer down the line if I got on well with CCR diving (ie greater than 40m dives etc). OC tech diving hasn't ever really appealed all that much, so this seemed like a potential alternative.
Anyway, back to the subject; for me, the biggest issue with the Discovery is that at the moment there is no further progression path, though Posidon say there is a trimix/deco variant coming. It seems to me to be an interesting bit of kit for me but I'd have been learning to dive a unit with a limitation and no current progression beyond it (yes - I know the Evo has limitations too but that is WAY beyond my level and not something I'm likely to approach for years, if ever!)... I'm not rich enough to spend that much on a unit and then for Posidon to can it, leaving me to go back and learn another unit to take my diving further! Still, let's see how it gets on...
