What is with you dude... YOU DONT KNOW ME... GET IT??? You have never been around me for more than a couple of hours when I came all the way to Port townsend and back to graciously pick you up and drop you off for a dive that I didnt invite you to, nor did you contribute to the gas fund. Thanks alot.

What is it that has got your cheeze in a wad? All I can think of is the "running out of oil" that occured on the boat... and hey,,.. guess what... as it turns out,... I didnt forget to add oil, and we didnt run out.. turns out I had a faulty sensor that has not been reading the oil level correctly as Matt and the boys can attest. I know.. let me guess.. the sensor failing is my fault also...seeing as how I had just bought the boat.... Other than that.. whats your beef.... Spell it out already...

do you live with him and dive with him? where do you get off saying that Cory won't take care of his gear. For chrissake Richard, give it a break!!!!

Maybe he will, maybe he won't, as i said before, there is evidence out there that he takes impeccable care of at least some of the items in his scuba stable. You are in essence, a complete stranger. You really have no business even making a comment like that, its just ass talk.

Yeah, you should probably back off this one, Richard.

FWIW, I have a rep for being hard on gear, and I'll be the first to admit I'm not the uber-anal retentive gear maintenance nazi. You don't have to be that way to be a good CCR diver, as long as you ARE careful and thorough about doing your checklist and changing your Cells on time.

And having the toughest freaking make of rebreather in the world doesn't hurt. :supz:

Probably the vast majority of them- but nobody can be sure of that; just my best guess.
I guess what I was trying to wring out of our gang of silent batsh!t crazy CCR divers is that there seems to be enough to go wrong outside of a gear malfunction. I'm guessing that toxing can easily happen even if your rig is maticulously maintained. While I think his reasons are unsound, I'm not trying to stop Cory from buying a rebreather (as someone pointed that this thread is only probably only egging him on) but I'm curious to know what else goes wrong.

From where I sit (read: a place of relative ignorance) CCR's scare the living crap out of me. I say this not just because I'm prone to jewy woody allen yenta worry. The level of complexity... in the gear but also in problem solving and increased need for situational awareness.... far surpasses what the average diver... even most tech divers... experience while under water. There has to be a reason why the CCR course is so intense?

For the record every time I type CCR I think:

"Do you find them much these stolen cars?"
"Sometimes but I wouldn't hold out much hope for the tape deck."
"Or the Creedence."

One of the things I hear brought up alot both with CCRs and technical diving in general is that you need a "good" reason to do it. I've always been puzzled by this type of statement since to me it implies that someone other than myself gets to decide what constitutes a worthy reason. If I want to go to three hundred feet to watch plankton float by so what? My motivation for going deep (or using a CCR) has no direct correlation to the safety of the dive. Understanding the risks involved and the limitations of my gear and myself as well as getting the proper training and building experience are what will determine the safety.

Here's how I look at the whole CCR vs. OC thing. It's like cars and motorcycles. Theoretically and statistically motorcycles are more dangerous than cars. However, as a human, capable of exercising free will, you have the ability to skew the odds. You can't magically make either one completely safe, but you can increase or decrease the baseline risk through your own efforts or lack thereof. Who is at greater risk, a 16yr old texting and driving, or a motorcycle rider who is intimately familiar with the physics of riding and who rides with extreme alertness and caution? Now granted, if both are exercising equal levels of skill and caution the one in the car is safer. But criticizing a person for going CCR is like criticizing them for buying a bike. The buyer and the critic both have a point and in the end who's to say who's right? It's a personal choice.

His whole unit had been flooded the previous year, and he just dried the cells out and kept diving them......past their expiration date, and after a full immesion in water. They were badly current-limited. And his solenoid had been taken apart and reassembled with a crucial part upside down- it was leaking ~10 lpm into the loop. By contrast, the orifice in my manual ccr is set at 6 lpm. While this is up to the individual's metabolism, 10 lpm is "off the charts". I'd go hyperoxic in minutes at that rate.I don't mean to disrespect the dead, but I heard his death described as "suicide by rebreather," and, well- it fit.
Yeah it was the solenoid mods that I was thinking of that really killed him. I forgot about the weird choice of dil which pretty much prevented any ability to flush away that 10lpm even if he'd done it. I just remember everyone (myself included) thinking he had some sort of CO2 induced seizure due to his weird behavior immediately prior, when it was really more like panic at being unable to drop the ppO2.

Oh good grief. There's plenty of evidence throughout this board and even this thread.

Actually it does, statistics amply demonstrate that deeper is more dangerous on OC. To some extent its true on CCRs as well, but they tend to be riskier in general anyway so its harder to draw a trend. The thread about the "deepest woman" record chasing death (on CCR) is salient to this topic. It was only last week on TDS. Also the deep air lala stories in Exley's "Caverns Measureless to Man" really open your eyes to perspectives on risk and "acceptability". I can loan you the book if you'd like. If your waffling on a dive one thing I suggest is running your ideas and concerns by your spouse/SO, that can really remind you (me, whomever) about "values".

I'm all for people diving however they wish, and more power to Cory if he wants more toys. I can still think its a bad idea and don't see any compelling reason to do anything more than agree to disagree.

Lol, I spent almost 3 years in Lander, WY pop, 8,000. Nearest and only diving was some spring north of Casper :(

No, it's not like that. I'm paranoid about my gear, not my ability to dive it. Toxing doesn't just happen- you have to DO or FAILTO DO something important in order to get yout P02 into the danger zone- assuming that your displays are showing the correct P02. They're machines. They do what they're told to do, as long as they're working correctly.

You're right and wrong all at once, here. I think the level of complexity is overstated. They're pretty freaking simple, honestly. I know *exactly* how my Meg works. I have *no earthly idea* how to rebuild an OC regulator- a device that's FAR more complicated than any CCR. CCRs are simple, straightforward machines. Now- analyzing failure modes, and how to recover from them- THAT can get interesting. Yes, problem solving skills are good here. But, you make it sound like rocket surgery, and it just isn't *that* hard.

You asked for opinions and got them. Many people feel that OC is safer than RB's. We are not telling you that you do not have a choice or that we won’t let you do it. We are telling you it is probably more dangerous and think you shouldn’t do it and if you do you may get killed. Richard made it a little too personal though.

I'll take you up on the book, I always love to read about diving.

My point was that wether my motivation is to "just go to 300 ft" or wether I'm going to 300 ft to look at the Admiral Sampson isn't going to determine how safe that 300ft dive is. And in recreational diving the value of the doing the dive is subjective entirely.

Point taken. Of course, I wear my CCR on my back, take it apart and put it back together all the time- heck, I exchange body fluids with it. I think it's fair to say I'm more "intimate" with it than you are w/ your mixing stick.

I appreciate all the advice that everyone has given me. Very much so. Unfortunatly Jeff, you are falling into the same trap that Dick has fallen into. Your basing your opinion on what you read on this forum and have made wrongful conclusions based upon your assumptions.
I mean, if thats how your decision making process goes, so be it... but you will find out that in most cases, once you actually meet someone, that they are seldom the person you had imagined.
Go try internet dating and see what I mean.... Its amazing how that 350lb woman that showed up was 150lb hottie a few days ago on the internet.

Richard,..

I defy you to cite a logical example and conclusion of something I or someone else has said about me on this forum that leads you to your conclusions....

Is there an issue Spat? Im simply responding, politely, to Richards remarks.... Well within the TOS...
The comments made by Richard are not acceptable. He is calling me dangerous, irresponsible, ignorant, and that I do not maintain my gear properly, in public.. This potentially affects peoples views of me as a dive budddy. I wont stand for it. If he has valid reasons for his claims.. Out with them already... lets discuss it!
Sure.. call me a hot head, arrogant, maybe even eccentric, over zelous... but not dangerous or reckless.....

Sure. Learning OC was easy, for me. But it took me 50-75 hours on the Meg to get feeling happy again.
