Decompression on Explorer

[Ken Hawk]

Have you had a go on one Mark?

 

[barrygoss]

and if he was not being a Pompous D*ck out of the gate,

et to brute, p.s. the d*ck doesn't need capitalisation in English.

How about the Gem, or ay other scr? Does the human race, divers in particular, never try new things JUST TO TRY NEW THINGS?

it isn't new technology, remember the dolphin? Maybe your marketing strategy hasn't looked back at what's failed because it didn't work. Some of us looked on while that happened.

Just to give you an idea of where this unit fits- I have done more than twice the amount of classes on the Explorer compared to how many I have sold. That has resulted in more classes and sales of other RB's.

no you've sold more courses. McDonald's has sold more food than anyone else, doesn't mean it's Michelin star though.

This includes going back down from a tech RB to the explorer.

nice! what real RB's are you qualified on?

Anyway, I called you on another thread. Still waiting.

Do You Even Dive Bro?

I saw Doctor Fish get in the water, he's done it at least once. Might've been a try dive

+1 this thread reminds me of a circular conversation I once had with a draeger rep when they were pushing the dolphin as the future of diving many moons ago.

you are correct, I was typing fast and didn't catch it

My comment-and again you all have such a self centered attitude- was about NEW divers who would like to learn about Rebreathers, not about technology. But since you brought it up, there are a couple thing different from the dolphin. I teach that during class. Maybe you should attend.


My comments are not a marketing strategy, I just enjoy getting a response from people who think arguing on the internet actually results in a win for anyone.

I was there also, watching and learning. But my CV is not the issue(if it is then you are just attacking me and not interested in getting info about something you seem to be soo interested in)

Again, you have never met me or dived with me, so why do you care?

I built my first homebuild and went cave diving with it over 15 years ago. I dive and teach the Explorer and the P2. I am sure there are many people here that have more experience than me. Buuttt that's not the point.

No doubt, but it was a joke, google "do you even lift bro"

Ah context.
But you said, "Do you even Dive Bro?"
and Do you even lift Bro is meant as : Do You Even Lift?***8221; (DYEL) is a condescending expression used on body building and fitness forums to question the legitimacy of someone***8217;s fitness expertise or weight lifting routine

So either you were trying to be condescending (and failed) or were joking (and failed)
I understand irony is a hard to understand concept in your parts.

But the irony of that original statement is awesome, hows the weightlifting going? neck getting a workout or a bit sore/red?

PS still waiting for the profile and why it's better than OC 32% throughout the dive.

PS (not seen gobbers in the water, I have run some math with him, mostly Daltons, you know him? about 1801 for that bit of math. Your country was 25 years old)

 

[H2Ocaver]

actually laffing out loud, so far I had had about a dozen people read parts of this thread and two responses came from almost everyone

1. "What's wrong with those English guys"
2. "haha, do u even dive bro"

so far this evening, I have heard -"I'm hungry-do you even eat bro", "we need to stop for gas-do you even pump gas bro", and the best one while driving and someone cut in front of my buddy "DO YOU EVEN DRIVE BRO!" to that I said "settle down, are you even british bro?"

So thanks to Barry I am sure I will be hearing upset British jokes and Do you even-Bro jokes for the next few days.

As far as the profiles, I will post one when I get a chance to pull one that is not from class.
...I'll be diving this weekend for fun, I'll take one of the Explorers up to our favorite hole and get a good example for you. Why don't you let me know what you want to see, or just a dive that's better than oc on 32.

And that last comment is coming from the country that got it's behind kicked by this country when the English were too much of pain to deal with. How's that British Empire doing now? Hell even in 1997 you gave up Hong Kong, and even gave up this forum. Not to good of a hot streak, eh?

I really hope you guys are smiling, this is too much fun. I love British Humor, television, Motorcycle racing, History, and Cars. My Dad (RIP) and I restored a 66 Triumph Spitfire MKII, I loved that car and the time spent with my dad. Anyway, I love you guys, really do.

Can we forget the personal attacks and get back to answering a valid question that was made by the OP.

As far as decompression goes the nature of SCR means that you will not get as extended of no decompression times as you would diving nitrox because at any given time the PO2 in your loop is lower than what you would be breathing if you were on the same nitrox mix OC. That could definitely be considered a con to SCR vs OC. I feel there are many more benefits that diving a rebreather offers.

I dive many full trimix rebreathers and still enjoy a relaxing easy dive on the explorer. If you are interested in doing deco than I would suggest that you consider CCR and not the explorer. It is depth limited and designed for a recreational market (No one is trying to hide that fact).

I really don't care if some of you think it is expensive overly complicated or not the right rebreather I am just trying to honestly answer his question. He lives in a different continent from me and will probably not be buying it from me.

If you are curious about the DCP and why you might select different settings on it there is a lengthy thread of me and few others answering Fish's questions about it. It is a little bit more civil than this one.

 

[Pat413]

@ Michael: +1 mate, and you never know if I would not come over and dive with you and buy something:cheers:

Indeed I would dive it only in REC together with my girlfriend and she goes not that deep, so the Explorer would fit 100% these dives. The question was how the unit reacts in deco and this was perfectly answered by Dinspiration. I see the benefits of Explorer in: Warm gas, easy going and handling, light for traveling, 2 hours dive time (on OC I would need minimum double 12L), weight dive ready...
So all good for me. And yes, for serious dives I would take Boris or Sentinel.

Cheers, Patrick.

ello bro .
i dont have the time at the mo to kick your arse some more ,
have other things that need kicking right now ,
but ill get back to you after you post some profiles

cell read outs for ppo2 s would be nice ,
nitrox mix used , gas in gas out ,
time at each depth , and the dcp setting for each depth , maybe the max injection-rate for the solénoïde LPM
thankyou ,

ps you need to get that manual sorted out , i see it shows a dive log with a 36m dive on nitrox 36 for 30min and a gas use of 600psi ,

AS FOR all the shit flying about , i think you will find , the first bump was tossed in by your good self ,
but hay now problem ,
you keep at it ,

profiles first , try toss in a wreck dive with a real bottom time please , the 2hr at 6m dive im not in two , but toss one in just for fun ,

catch you soon ,

 

[ebt]

I'd be interested in seeing some proper profiles. Proof is in the pudding and all that.

Just for clarity I'll add that Im not the target market, for recreational stuff I love the simplicity of a simple tank of nitrox or two, where you know whats going on without resorting to extra complexity.

i think you asked a question about the unit going in to deco . and it was then answered , my olny input was to say it runs air deco cos the numbers / real ppo2 will be a lot less than your nitrox cylinder , and could be at some points v close to 21, so not as safe as was suggested, ie less safe than a nitrox dive but more safe than a .21 air dive ,

o and your out of gas be4 deco , well it will want you to move up be4 that , as for not knowing what your breathing , well you may be able to see it blow by blow , but it will change so much you wont be able to keep track , so in truth once you lose the depth Advantage ie the unit is not doing sfa .(daltons law, in play ) the ppo2 will be up and down , like my x wife nickers , she was a go errrrrrrrrrrr

after that it all went down hill with the turd tossing

 

[Nitrogenius]

Nice Fred here..
Let me collect some goodies..
First of all what is all this:

O2 percentage in the loop is around 5 to 6 percent less as in the tank, so you can calculate it by yourself. And with knowledge of rebreathers you should know that. Have a look at SCR. The big point of the Explorer is, that its a dymamical setpoint controller. Go for a course,, its not all written in the manual.

Blue, you are so right. But the problem is these guys are professional poo-poo 'ers, they want to Sh*t on anything they don't dive/understand, and they are way too damn cheap to pay for a class to answer all their questions and try a dive on one..

If you want to know how the unit works get a class bollocks ??
Is this a super secret box?
If you think people are wrong here, then why not starting with explaining how the unit is supposed to work? On all units I can gather infos to make an educated choice if this fits my need and interest upfront, why is this supposed to need a course to get simple questions answered?

ok, all dives on nitrox have nitrogen loading, as long as you get to do a safe dive-who cares about higher loading?

Seriously? Are you getting the oxymoron or paradoxon you are expressing in that sentence? (Are you even deco modelling bro? )
Safe dive and higher loading do not fit too well in my book.. certaintly a lower load is safer, no?

I have no issues with the explorer, I think it s a great unit for those who wants a light unit for diving within recreational limits. I have tried different units, but the Explorer is not for me, I just can't justify the cost for what it does.

Jeppe that is a somewhat funny statement from you.. Maybe I remember wrong, but didn't you start diving ur P6 (and invest to it) when there was not even a "Deco battery" yet and it was completely unsure if this would ever exist?
How was cost for what it did at that time then ? :sarcy:

Lastly which already been responded to by my fishfriend from that lovely island trying to rule Europe but yet not wanting go metric or share a currency:

@ Michael: +1 mate, ...
.. The question was how the unit reacts in deco and this was perfectly answered by Dinspiration.

So what are you complaining about?.. You question has been answered so let us play a bit.. Can't even call it a highjack since the OT has already been covered

 

[Mark Chase]

Have you had a go on one Mark?

Why would I seek to have a go on a recreational NDL unit? It fits exactly nowhere in my diving requirements. I have mode no coment on the way it dives? What insight could i possably gain from diveing one?

As i say my views are purely bassed on my experiance with various units and using that knowladge to analise the function and performance of other units

And i repeat i have noting against this unit. I just find it a buying in to the whole CCR thing an limiting your dive choices in such a drastic way a very odd choice. And I wouldent dive this unit without a bailout tin unless i was planning on using only 2l out of my 5l supply, nor would I dive any other CCR without one.

Thought you may have had a go just for the craic

 

[Mr fish]

http://www.rebreatherworld.com/new-to-rebreathers/3874-measuring-vo2-on-a-scr.html#post39425

ken

down load this scr sim , go to page tWo and put in nitrox 40 , and a flow rate of 9.5 lmp

on the left hand side you will see some numbers under VO2 , IE , the divers o2 use at low to hi work rates ,
the other side shows the fo2 in the loop

what you see is the norm setting for a scr , the last number is 19 at a v hi work load , if you dont have 19 or better the diver would pass out ,


now play with flow rate , see what happens keep in mind the .19 .

now this unit is smart for a scr , cos it can read the loop ie has cell s and also can put more gas in or slow it down

get your head round that and ill tell you some more ,

ps forget about cc rebreathers as you think you know them , ie this unit can not add to , it can only use what it has , the ppo2 controler is doing nothing more than stopping gas going in whaN the unit had a depth advantage , have a think about what it trys to do , make long dives keep you away form NDL

 

[Mr fish]

now lets say .19 is the ace in the hole ,

put a 6.8lpm flow rate in and watch the ace move up , now as long as the diver work load is less or matches the V02 of 1,75lpm all is well but if the diver was to over work, said unit can see this and add in some more flow , thats the smart bit ,

but as you can see the smart stuff comes at a cost , its all a Compromise, when i say cost , i mean you now have only the unit to keep you alive , cost the gas flow on its own wont if you over work your self ,

all i wanted to know is were kev hides the ace , along the vo2 line ,
and having a few profiles would have helped me to do that ,

as for the unit im not asrsed about how its sold or dived , get on with it enjoy ,

but dont try pulling my pisser ,


ken now you know what to look at , put nitrox 32 in and move the flow rate till you get .19 or better for hi o2 use
and play away ,

if you know the flow rate.s you can work out the cylinder size you want for the dive , or what your 5l may do / time wise

if you know were the ace is hid you could work out a lot more lol

No, Mark is still waiting for a go on an Apoc, apparently they are manufacturing a special one that doesn't have any ball bearings or electronics for him to break. (apparently it looks just like a Drager Dolphin)

You seem to want to know how the unit works, I believe what is is going on here is that you are taking a class, or just being schooled.
No, the manual is online, what's the secret you are missing?
Ask a question, get an answer. Fish wants numbers, I need to get those for him when I get a chance to do a dive in those parameters, sorry for the wait.

Seriously? Are you getting the oxymoron or paradoxon you are expressing in that sentence? (Are you even deco modelling bro? )
Safe dive and higher loading do not fit too well in my book.. certaintly a lower load is safer, no?

Again, the single biggest problem is that people that are already tech/ccr are wanting a unit that does deco/ deco planning and other features that this unit does not make available. So your perspective is skewed, you are asking a why the unit does not do things it is not designed to do. That is not for me to answer. It's about perspective.

Like Thornton mentioned, it's an scr and it's a different kind of scr. It extends a gas as efficiently as possible based on the sensor input and the diver's manipulation of the dcp. The tissue tracking is done based on real time data put into a basic deco algorithm. It's so damn simple it evades those that are trying to look behind the scenes for secrets that don't exist.
