Decompression on Explorer

+1 for Bluescuba.
But Blue, it can't be so simple, fish is having too many questions for the Explorer to be that simple.....

questions that dont get a answer ,

in the manual it shows a 18m dive on 40% nitrox ,(dcp95%,) its shows /says after about 57min you run out of ndl. whats in the loop to give that number , and is that number in the loop not to far from 21 , as its not even close to 35 ,

and thats why it deco s you out on air , yes or no ,


having skewed bias toward technical , i just feel the need to know what im breathing

Can I ask a cpl of stupid questions.
If you were to do a 40mt dive what mix would you use and what sort of BT would you get
I presume you can't fill it with 32 to 40%
and how much is a canister of lime

About 10 min...Then you are up shit creek with NDL. :sarcy:

The explorer is more suited for a shallow reef/wreck dive, and for that it is probably one of the best, easiest and lightest units available.

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.
@Ken
Go close to 1.6 or your preferd ppO2. For BO take air or whatever you like and maybe use a second comp. Yes, the Explorer is designed only to use NX 32 - 40. Scrubber is 1,5kg so far. CE test result is 40min in 40m in 4°C water + injection rate 1,6l and breathing rate 40l/min. The duration time changes immensly as soon as the water gets warmer and/or with a normal breathing rate.
Aurora Blue? people say maybe a new owner :sarcy: Hope you dont have to wait to long.
@jeppe
exactly - its designed for sport diving ( Explorer Sport Rebreather ) so, in the end you have to compare it with oc diving - single tank and up to twin 12 - or with other rec Units.
But in this league the Explorer is unique so far, working and electronically controlled. The rest isnt as light, as easy to learn/dive and reliable without the more demanding skills/knowledge/possibility of failures of CCRs. All you need is a NX tank. 40cuft or 5L or whatever. Thats it.
I personally like the Explorer for easy diving. Small, light and easy to travel. For the more challenging, deeper or extrem TX diving i use one of the best machines designed for that too.

LOL, I guess the CE testing is void, in terms of depth/duration, seeing that the Explorer is a NDL unit, and 40 @ 40 is.. well... uhmm.. Not even close to NDL :sarcy:

From a scrubber perspective, I can understand it, but it tells you just about diddly squat about real time usage. It is much easier to put it in a perspective - You will run out of gas/NDL before your scrubber is exhausted :)
 
This is the test only for scrubberduration. This means nothing more than what is says. With the same basic connditions as used on all other units for CE tests. Why this is funny for you i dont know.
And yes, as you already realised, a 5L tank in conditions like that is not enough. But as well its not meant to be.
In reality you would be positivly surprised about the Explorer, believe me.
As i can see that you are in the beginning, enjoy diving, dive different units, have fun and gain experience!
 
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. Either that or they are afraid that they will be proven wrong/ surprised that the unit does EXACTLY what is says it will do.

As far as dive planning it's fairly easy-considering it is a RECREATIONAL unit. If you want to know what's in the loop you-look at the status screen while you are diving! If you want to know how long you have left or what consumable will last for how long-look at the status screen! These questions are basic in the class. It is really sad that these guys just want to start B.S. But we should realize that they are EXPERTS on this (and ALL) rebreather, yet don't understand it.

looking at my logs- Spiegel Grove -runtime 92 mins, Max depth 138 ft, avg was 76 ft, multilevel dive w/ 3 mins deco, still had ~400 psi in the tank, Filter time remaining was about 17 minutes. This was a great RECREATIONAL dive for me.

It's really sad when a PADI zero to hero instructor comes on here trying to blow the latest flavor of high margin smoke up the backsides of people who by their very definition are not their target audience (uneducated jo public v's technical CCR divers) and try and tell us that accepting most of the limitations of CCR in terms of cost and complexity per dive while loosing all of the advantage of CCR in terms of higher PPO2 and longer NDL's is some how something that we should all go take a course on to find something that is known to anyone that has done a CCR MOD 1 ticket.

Frankly, all questions are valid in this place, being an ar$y know it all who wants to make money from a community that you don't own ain't......
If I want AIR NDL's I would dive OC.
 
Again, this unit is not for you, It is not for technical diving, so why do you take offense. It's not a CCR, it is an eSCR. As for my diving career, I don't need to go into that. The facts speak for themselves, the unit does what it is supposed to do-I have not seen ONE of you say otherwise, I will take that as an agreement from you-it does what it says it will do.


I need to address this logic-" is some how something that we should all go take a course on to find something that is known to anyone that has done a CCR MOD 1 ticket. "

---if this is something these guys already know then why are they asking? to stir the pot? Shame on them, shame on me for participating.

If this unit is does not do what you want or you have issues with what it claims to do, why don't you go find an instructor and -face to face- ask for an explanation and a test dive? If you want nothing to do with it, then why are you here?

I dive the unit, I like the way it works, I offer anyone here the chance to dive it with us, - no charge, just sign the usual paper work and listen to a little instruction and then have some fun. If you have any questions afterwards- I promise to be nice and helpful.

So it's not ok to attack someone, but it's ok to attack someone.
Anger comes from guilt and fear, you seem to be angry.

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.

I have no issues with the testing either, just that I think it is a bit void to test the unit in an enviroment that it is not aimed for, but that is more related to the CE Standard than the explorer. :)

BTW I am a OC diver with no CCR or SCR experience what so ever.
My questions were to see if this unit would be of any use to me.

how many days does a course take?
 
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.

maybe he can post that profile po2 and time at each depth lol

be4 you jump the gun id have a read of this thread , good read from some internet gurus and well know cheap barsteward , http://www.scubaboard.com/forums/rebreather-diving/406539-hollis-explorer-rebreather.html

ken stop being cheap shit and book a days play on the unit , , maybe one of the guys in the thread can help , they seem to know whats what , lol going from the numbers tossed about your going to get a laugh if nothing more ,

professional poo-poo 'ers, lol . the world is my lobster ,

Ken, it is all in using the DCP properly and planning the dive as a multilevel, then diving the plan. The unit does most everything else for you. (except carry your b/o)
 
looks like were back at post 23 ken , have fun ,

im off to do some poo pooing over on another forum . see you later , whan them profiles are posted , lol
 
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?
