Decompression on Explorer

[Ken Hawk]

DCP?
what did you take as bail out on that dive and what mix did you have in the cylinder, how long were you at 138ft 41mts

 

[Jeppe]

I would be very intrested in the logistics of the spiegle grove dive, If I could go to 40mts with a 92min run time this would be the perfect unit for
me.

I would imagine a dive like that would be:

40/5
30/10
20/20
15/30
10/30
6/3
Runtime: 100 min (ish)
NDL

Not sure about gas calculations though, as I have no clue what the normal gas consumption on an SCR like the explorer is. But dive is just manageable on a twin 12L with EAN28

 

[Mr fish]

You are not going to get a profile, there is no standard profile, we go over this in class. Would you care to take a class?

no thank you . and i know i wont see a profile , as that would show a piss poor ppo2 , once you lose the depth advantages

so tell me this over 3 days diving you on your pisspoor nitrox and say a poopooer on oc nitrox with a real ppo2 , right through the dives , wiho would have the higher nitrogen loading ,, and that is stanard , no way round it ,

why dont you just flog it as a gas extender , and not try to bullshit us its a ccr or a scr , or even a true nitrox , as it none of them ,


lol get a life m8 , and stop worring what some old tosser post on the inter web

did you know hight nitogen loading can lead to the bends , lol

also do you think it good to let young noddy play breath me down on a hot nitrox mix , , o i forget hes ok as his put 1.2 in as a set point lol

well is its a 5l in the unit and 7l bail out , 12l id stick with a 15l and toss OFF a few mins dive time , and for 5mins at 40m id prob toss that out the window to ,
but hay each to his own ,

lol just kidding id smack its arse and take what was needed ,


think its time for me to call it a day , this poo pooing is keeping me off ebay , iv a got a bid in on some 2nd hand underwear ,
catch you later , thanks for the post ,

 

[Ken Hawk]

Mr Fish do you think I best stick to air and fiddy then

 

[Mr fish]

Mr Fish do you think I best stick to air and fiddy then

only if you want to keep diving them 60m wreck,s
other wise go shoot your self in the foot m8 ,:big:

got to go , as im looking on ebay see if i can get one of them new nitrox decaying diving machine,s

as my bro need his pool cleaning ,

 

[H2Ocaver]

What exactly is a fake po2?

,

right through the dives , wiho would have the higher nitrogen loading ,, and that is stanard , no way round it ,

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

,

why dont you just flog it as a gas extender , and not try to bullshit us its a ccr or a scr , or even a true nitrox , as it none of them ,

All SCR's are gas extenders, is this a revelation?

The unit deals with po2's greater than 1.6 in a safe way, there is no breathing it down. Less than 1.6 is what you get otherwise it is very clear that you need to ascend.

uuhhhh, that's not the same dive then, is it?

 

[H2Ocaver]

pretty close Jeppe, run the dcp all the way down in manual mode for the deep part and bring the dcp up as needed to stay out of any serious deco, then drop it back down on the shallower part to save gas. Back and forth in this fashion-in manual mode- makes the Explorer a great way to use less gas and get more dive time on a single dive. This is actually what it is designed to do-vary the po2 and parse the gas and use the sensors to keep it running with a safe loop.

I will say that the auto mode is not nearly as efficient at this,so manual is the best way to do it. I just wish the instructors took a little more time and one more dive to show students how to be in control.

I would imagine a dive like that would be:

40/5
30/10
20/20
15/30
10/30

Oh, come on guys its an SCR unit - nothing more.
Well made with a couple of new features and working nicely in the region for what its made . Thats it, so please treat it like that. You all are grown up are you?
Sure you can discuss Decompression, filling it with TX, exceeding Divetime Scrubberduration etc, its interesting for sure but if you need a unit for dives beyond rec limits go and get a proper CCR.
Have fun with your different machines! Almost all have interessting or unique things to deal, learn, teach or dive with.

had my fill of all your smart arse ing about ,
so enjoy your day ,

ps

this nitrox decaying machine


first of can we all agree that most companies/ rebreather manufacturers

put factual Information in there rebreather manuals,

so let,s take that profile of a 18m dive on nitrox 40 as fact ,

that profile give,s a NDL TIME OF around 57mins ,

that tell,s me the ppo2 is round .67
fo2 .24 and not a few point less than 40 35 or what ever
other numbers have been tossed in the mix ,
the DCP is at 95% and that,s the best it can do,
the ppo2 is less than would be seen if the diver was on oc 40% ie we would have a ppo2 of 1.12
and prob more as a oc diver on a 18m dive may run a ppo2 of 1,3 / 1.4 .

so the numbers, from the profile, the factual information in the manual,
tells me im diving a nitrox decaying machine, not a nitrox rebreather / scr ,
it,s letting my loop ppo2 drop to a point that ist detrimental to MY so called nitrox dive ,


so given that, i must be ending my dives with a higher nitrogen loading, than i would if diving oc nitrox , a scr or a real ccr ,

now if it can only make a ppo2 of .67 at 18m with the dcp at 95% it make me think whats in knocking out in 10m or less on a dcp of 10%
its for sure plenty to keep the diver from falling asleep , but its not up there with a real nitrox gas ppo2 ,

also riding the high ppo2 down at that start of a deeper dive TO gain some small advantage in the avg ppo2 is NOT what i call R type diving .
but hay you seem to move that R all round the ball park, dont you think as soon as noddy figures It Out
he will be hitting his mod with a ppo2 of more than 1.6 and riding the mix for all he can get out of it ,


now no one is saying it cant do a 2hr dive , but i do think your misleading divers with your posts ,

and you need to post the cons . along with the pros , ie tell the truth , and not just as you have been handed it ,

i dont want to piss all over your party , but if you wont come clean then . your fair game .

NOW if that profile is all bollox and you can get 3hr ndl at 18m then id be v happy to say sorry , i was wrong . but post your profile to show its SO, lol just post the cns count for your so called long rec nitrox dive,

and just be4 i go , please tell me more about the set point controler cos i think that is a joke also .
this red herring that would only work for a v small part of the dive as the unit cant make the numbers once the depth advantage is lost ,
and if it could it will piss all the gas away and you can say good bye to your 2hr dive times .

 

[Peter L]

I think our boy is a bit bitter and twisted because he as per instruction put his dollar in for his instructor cert on these wonderful units and there is a significant lack of willing punters or bikini babes queuing up at his door to get into this brilliant new diving opportunity, sorry money making opportunity. That's the problem with PADI, they will take your money if you ask nicely.

Perhaps you should have stuck with these beauties, they seem to get way more babes.....

 

[Pat413]

well: after all, there are only 1 or 2 valid responses on my original question... I think people who don't own or even dived an Explorer should just read and learn. And if they have an intelligent question or remark , then post here. Thank you.

this nitrox decaying machine

All rebreathers decay the po2, I don't know why u don't get this.

that tell me the ppo2 is round .67
fo2 .24 and not a few point less than 40 35 or what ever

the DCP is at 95% and that,s the best it can do,

this is not correct, just plain wrong.

the ppo2 is less than would be seen if the diver was on oc 40% ie we would have a ppo2 of 1.12
and prob more as a oc diver on a 18m dive may run a ppo2 of 1,3 / 1.4 .

It does decay the po2, but the resulting po2 is very different from the numbers you calculate. It is very easy to bring up the po2 and it is very easy to verify the po2 by scrolling thru the status screen. And any instructor worth a damn will show the student what to do.

so the numbers, from the profile, the factual information in the manual,
tells me im diving a nitrox decaying machine, not a nitrox rebreather / scr ,
it,s letting my loop ppo2 drop to a point that ist detrimental to MY so called nitrox dive ,

so given that, i must be ending my dives with a higher nitrogen loading, than i would if diving oc nitrox , a scr or a real ccr ,

When u say detrimental, what do u mean? Is the diver not getting the dive they want? Is there some end result not being achieved? Ending the dive is ending the dive, once out of the water and safe and dry-who cares what loading you went thru? I am not conceding that you are correct, I am just wondering what the problem is while the diver is on the boat or driving home.
Is about a second dive or multiple dives over the day? I have never had a problem diving the explorer when it comes to getting as much or more than other divers on oc. Your conjecture just does not agree with reality. Could the numbers in the manual be a bit conservative? Probably.

now if it can only make a ppo2 of .67 at 18m with the dcp at 95% it make me think whats in knocking out in 10m or less on a dcp of 10%
its for sure plenty to keep the diver from falling asleep , but its not up there with a real nitrox gas ppo2 ,

It's displayed right there on the screen, If you took a try dive all of your questions would be answered. Or is it just your objective to poo poo the Explorer? If this is truly your desire, to crap on the Explorer, then I will just shut up and leave. But to go on and on about a unit that you have never had in the water is self serving, for whatever reason.

also riding the high ppo2 down at that start of a deeper dive TO gain some small advantage in the avg ppo2 is NOT what i call R type diving .

Thankfully, what you say does not really mean much, especially since you have not even dived the unit.

Do You Even Dive Bro?

but hay you seem to move that R all round the ball park, dont you think as soon as noddy figures It Out
he will be hitting his mod with a ppo2 of more than 1.6 and riding the mix for all he can get out of it ,

Right before this statement is where you should have stopped. At this point you are proving that you are clueless and really need to do some hands on/wet research.

The Explorer HUD and display alerts when the onboard gas supply is at 1.6 po2, the unit makes diving beyond 1.6, in violation of the onboard gas, VERY CLEAR. So the fact that you think that it will simply allow the dive to dive on with a PO2 of 1.6 or great is just a mentally deficient thought.

now no one is saying it cant do a 2hr dive , but i do think your misleading divers with your posts ,

and you need to post the cons . along with the pros , ie tell the truth , and not just as you have been handed it ,

i dont want to piss all over your party , but if you wont come clean then . your fair game .

This all would have been easier if you had just asked what I didn't like about the Explorer.

I don't like

-the DG05 repurposed as the controller-I just don't like that computer especially the screen. The fact that it uses British jargon like "filter" is kind of goofy also.
-I think the software should allow for deco with a full compliment of data that any deco diver would want.
-I would like an actual setpoint option, even if the DCP was to still be in control. Some combo of these would be more to my liking, but that desire is from MY perspective, We need to think in terms of the perspective of someone who is a rec diver and not versed in RB diving as we know it.
-I don't like the LCV, I don't like it's range of adjustment. I would rather have a standard type of dump/opv.
-I don't like the fact that you can not switch the controller to OC, but again-that's getting into more control/complexity and it would create a greater possibility of diver injury in the case of a mistake they made while in a real world b/o. Again, it is about the perspective of a beginner diver-not a seasoned RB diver.

There are a couple more things but I actually really like diving the unit and instead of just sh*t talking I call the manufacturer and talk directly to the guys that build it and ask them if things are possible or likely.
-

NOW if that profile is all bollox and you can get 3hr ndl at 18m then id be v happy to say sorry , i was wrong . but post your profile to show its SO, lol just post the cns count for your so called long rec nitrox dive,

and just be4 i go , please tell me more about the set point controler cos i think that is a joke also .
this red herring that would only work for a v small part of the dive as the unit cant make the numbers once the depth advantage is lost ,
and if it could it will piss all the gas away and you can say good bye to your 2hr dive times .

The setpoint controller takes a while to learn to manipulate well enuf that u can get more of what u want out of it, but it does work, I wish it was more aggressive.

Sorry Pat, but we get our fun where we can get it.
again, sorry for jacking the thread.

daltons law m8 .

I dont need to dive this unit or even see it ,
your numbers dont stack up , you talk nonsonce, YOU dive a unit with more gizmos than a jumbo jet , yet when asked to show a hand full of profile from your dives , you cant ,
sorry that just stinks ,

im done thanks , way to much shit in your long post for me to bother with , i just cant be arsed to pick it to bits ,

 

[H2Ocaver]

You quit first, I win.
I'll post a profile when I get a chance, gotta find one that isn't teaching, and we rent all our Explorers so the logs are all over the place. I'll get one up soon, if you stay and play some more.

Seriously?

Mr Fish is using an experiance level thats way above the pay grade of this unit to ask serious questions about its function. You would do well to try and get your head arround the issues raised.

I am personaly amazed when people spend out big money on such limited function dive systems but I only get upset by daft claims made by the manufacturors Thats why i am often found slagging of the P6 unit. Its not the unit per say, its the hype arround it.

[H2Ocaver]

100% correct Mark, and if he was not being a Pompous D*ck out of the gate, then maybe some serious discussion would happen. Also, some of these thing that he is asking are about data points that differ from dive to dive and person to person. If I were to put up the data he wants, he would do as he has done already- and Change the Dive data to fit his criticism -

well is its a 5l in the unit and 7l bail out , 12l id stick with a 15l and toss OFF a few mins dive time , and for 5mins at 40m id prob toss that out the window to ,

All of this to no avail, he wants to be critical just to be critical. It seems to me that he hates someone or he enjoys being a douche. AAAANNNDDD, he has yet to lay hands or dive the unit, but insists that we are not getting the dives that we say.



As for your point about what people spend their money on, would you say that there is no use for the Explorer, How about the Gem, or ay other scr? Does the human race, divers in particular, never try new things JUST TO TRY NEW THINGS? Does the warm moist loop not have a value? Does the weight savings not have a value? Does the lack of needing 100% O2 not have a value? Hell -does the intrigue of RB's not have a value?

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. This includes going back down from a tech RB to the explorer. We have fun in class and everyone learns something. The fact that none of this is your money should be of comfort to you. If someone wants to participate in a try dive, come on down I'll do it for free, just sign some paperwork and listen to a short some quick instruction. How can this be a bad thing?

Seriously?
