![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() | Re: Attention!!! AI O2 Sensor Recall mmmm, I think many over look how stable and reliable semiclosed ppo2 can be and dismiss it as 'too hard to do' or 'inaccurate' when in fact it is neither. Agree with all. But I'm talking perception, and building self-confidence. It is PERCEIVED by many as complicated and unreliable. In order to build your own confidence level, the best way is to show/prove it to yourself, i.e. try it out while your electronics are still o.k., so you can note how far the PO2 drops in your particular personal SCR scheme, so you know what to key in to your VR3 or other deco-tool. This is e.g. influenced by what you say: 1:2 or 1:3 breath-to-flush ration etc. You need to determine upfront for yourself if you need to lower it from 1.3 to 1.2 or 1.1 or 1.0, and adjust your decokit accordingly. In a stress situation, you want to fall back as much as possible on pre-determined and pre-experineced "tricks", if only to remove the worry that you might still end up a deco-victim (which is far preferrable over a drowning victim; deco is at least treatable, drowning not...). That takes practice, and in my experience this is not dealt with enough both in formal training, as well as in repetitive self-training afterwards.... but bottom-line, we agree. Suggest we don't pull this thread farther away from the AI cell issue itself (also my fault, though....). ciao, Tino. |

Id run the VR3 on Open circuit with an assumed FO2*, then you dont have to worry about changes in depth so much. Just punch in a lower FO2 than you know your likley to ever reach in the loop and away you go - conservative deco. *FO2 slightly lower than the OC gas FO2 to make allowances for the semiclosed drop eg Lets say my bottom bail gas is 10/65 when I bail semiclosed I switch vr3 to OC 7/65 (for example) and follow the VR3 OC deco, treating each subseqent gas switch the same (OC deco set vr3 at lower FO2 than actual deco gas) sorry for the hyjack

Yep, of course you're right: semi-close is much closer *FO2 slightly lower than the OC gas FO2 to make allowances for the semiclosed drop eg Lets say my bottom bail gas is 10/65 when I bail semiclosed I switch vr3 to OC 7/65 (for example) and follow the VR3 OC deco, treating each subseqent gas switch the same (OC deco set vr3 at lower FO2 than actual deco gas) sorry for the hyjack to OC than it is to CC, so makes sense. My SCR knowledge is getting rusty - too long ago I owned/dived a Dolphin & Ray. Ahh..... those were the days..... ciao, Tino. |

![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() | Re: Attention!!! AI O2 Sensor Recall A recall notice, which the Dive Rite Express statement is to all useful purposes, is not commercial advertising on any other major forum I know. True, but keep in mind that I didn't view it as a 'recall' (or recall by another name) but merely as a customer service issue. That's the fine line that is being walked here. One man's 'safety' issue is anothers 'customer service' issue. It's Stuart's baby and he can run it however he likes, but I'm not interested in trying to figure out exactly where the line is. However, a remark like ...Of course, my opinion is also that the resellers of the cells should have made a post here at Rebreather World to let as many Rebreather divers as possible know of the issue. After all it is a potentially life threatening situation. But perhaps my expectations are too high. ... means I have to explain why I have stopped posting anything business related here.![]() |

| Despotic Overlord ![]() ![]() Current Rebreather/s: | Re: Attention!!! AI O2 Sensor Recall Our staff was quoted a rate that seemed too high, and upon communication with several other Rebreather World advertisers it was indeed several times more than what they were paying. I brought this up with Stuart, he stood firm, and the budget was spent in other venues. No hard feelings, it’s just business. Really Mark? I asked you at the time which of our retail advertisers you had talked to and you would not tell me - I then checked with our 2 retail US advertisers and they stated categorically that they had not talked to you.![]()

| Despotic Overlord ![]() ![]() Current Rebreather/s: | Re: Attention!!! AI O2 Sensor Recall To the issue of ‘community comes first’, it seems to me that the community is best served by allowing all the manufacturers and retailers a voice too. If Stuart wishes to continue to exercise editorial control over my posts, the posts of other members mentioning Dive Rite Express, and exclude non-advertisers this is certainly his right. However, Rebreather World is no longer serving the community in an unbiased manner. There are conflicts of interest when the owner/operator has editorial and policy control of content, accepts paid advertising and has part ownership with a financial stake in the success of a for-profit retail store serving members. If RBW wishes to present itself as something other than a for-profit business then it seems like RBW should abide by generally accepted practices for non-profit organizations. This is particularly appropriate since RBW solicits and accepts 'donations'. Well I guess that would be your opinion Mark - after all you would then get to advertise freely then with out having to pay.However the fact is nothing has changed since day 1 if you want to make commercial posts or link to commercial sites - then you must pay to help cover the costs of Rebreather World - it is something that you agreed to in our Terms and Conditions. Thousands of hours and tens of thousands of $ have been spent on the site I give up my time but believe me if the money had all been coming from my pocket it would not have happened. It seems to me we have grown into a healthy community following our principals of if you are going to make money out of the site then you can pay to keep it going - if you dont like not being able to make commercial posts then pay to advertise or dont complain about it. Please don't try and spin what is good for the community when your focus is making money out of it. ... means I have to explain why I have stopped posting anything business related here. Why you have stopped? Nice spin again - however the fact is nothing has changed - always has been no commercial posts or links to them unless you are a sponsor.

A commercial post is any post that further's ones business IE. for profit.. Well that's the key issue and a very gray area. Any post that furthers a business could be interpreted to mean any post that contains information about any product sold, any fact about the business itself, etc. How are the circumstances to be interpreted, particularly in reponse to another post that might not be accurate? What differentiates useful information from advertising from spam? Is a post by any member become commercial if it refers to a third party for-profit business that is not an advertiser? Who makes that determination and what are the criteria? Let's take a hypothetical example to illustrate how unclear this can become... John Doe posts in a Rebreather World forum a question like "Where can I find cheap Snarfle for my Death-Trap brand rebreather?" The manager of Rebreather World Store then makes a post "You can buy Snarfle right here at RBW Store for $3/ton and by doing so you are supporting the RBW community, we also sell Effluent a competing brand". Someone else replies "I bought some Snarfle from SnarfleOnline.com for a great price of $1/ton, much cheaper that Rebreather World Store." The owner of Snarfle On-Line then posts "I've been deluged with calls asking about buying Snarfle at $1/ton. I'm sorry, but the sale price on Snarfle ended over a year ago and our price is currently $2/ton." The manufacturer of Snarfle then writes "We here at Snarfle Industries are aware that our wonderful product Snarfle is currently in short supply, but we have posted on our website a list of Snarfle Platinum Dealers who currently have stock on Snarfle" Whereupon the owner of Your Local Dive Shop posts "John, my store YLDS is just down the street from you and we have Snarfle in stock with no shipping for $2/ton also. I'm also a dealer for the Death-Trap and we have the new Hyper Death-Trap accessory that extends the life of Snarfle by 50%" Someone else posts "Hey what's the deal with the Hyper Death-Trap, how does that work?" Then the Death-Trap manufacturer posts "We have just introduced new Hyper technology for our Death-Trap series and here is a link to our promotional video that shows how it works". Brand new member snarflewiz posts "SNARFLE, SNARFLE, SNARFLE, we've got dirt cheap Sharfle here at Snarfle Works!" Someone posts "Hey, I just heard Muddy Springs Super Discount Dive Store is having a try-out day in the muddy ditch behind their store for the new Hyper Death-Trap, and if you order one at the try-out day you can get a giga-buck discount!" And of course someone posts "Snarfle is crap and the Hyper Death-Trap will kill you. I bought a Death-Trap, nearly died on it and YLDS wouldn't refund my money!" The owner of YLDS then posts "Well, it's true you nearly died using the Death-Trap, but we did tell you that you had to use Snarfle. We here at YLDS stand behind all our products but since you used Effluent, it's not under warranty." Which triggers the post "As the manufactuerer of the Death-Trap, we want to warn everyone that the new Hyper Death-Trap life extending technology for Snarfle does not work with Effluent. Only when properly used, the Hyper Death-Trap has been tested and proven to extend the life of Snarfle by 50%" Let's assume for the moment that none of these people are advertisers on Rebreather World with the exception of RBW Store itself. Which of these posts are commercial and should be deleted from RBW? Last edited by n2diving : 20th November 2007 at 19:43. |

| Despotic Overlord ![]() ![]() Current Rebreather/s: | Re: Attention!!! AI O2 Sensor Recall Mark, We manage just fine thanks very much and I trust the team. Like I said if you want to advertise pay up. If you dont have anything constructive to do other than to stir then please go do something else. Let me be clear - our terms and conditions are not up for discussion, you need clarification then ask a member of staff - follow our rules or dont come here. I have better things to do with my time. Stuart
