why hate safety devices?

[Blackwood]

The thread is not about replacing skill with devices. It is a question about what harm it does to have this safety gear as a redundancy.

Many times these things are hard programmed in ways that are fundamentally different than how run I dives. I elect to have as little contradictory information as possible.

It seems to me that whether superfluous gear is a liability or not is the true meat of this thread, so out of curiosity when do you consider 'redundant' to become 'superfluous'?

Seems to me that you are hiding behind the assertion that people have not read your OP just because you don't like their answers.

No - their posts make it clear that they have not understood the OP, or they are opposing a statement which I have not made.

Try again.

At first blush, I would have to state that it depends upon the training level of the diver relative to the conditions they are diving in - this is not part of the OP, but it seems to be the context that many posters are identifying with when posting.

He would make a great EU Commissioner! When they put a question to "democratic" vote they simply throw the question back time after time until by attrition they get the answer they wanted all the time.

You are welcome to take issue with position statements which I have not expressed. Isn't the WWW great?

And your posts make it clear that you're trolling. You have a history of choosing words that are intended to incite or misdirect, then you sit back and nitpick when people attempt to engage you in conversation.

I won't be bothering with any more of your "questions" ... I don't think you are really all that interested in the answers anyway.

As of now, you're on Ignore ... go "entertain" yourself at someone else's expense ... there's too many other people in here who are a better use of my time ...

Wow ... consensus on SB is a rare, rare thing however EVERYONE seems to agree in their responses to your question. I'd take that as a rather prominent sign.

I'm not going to reiterate everything that has already been said but would like to point out that your question was well and truly answered.

There may be consensus in this thread on this topic for several reasons

1) The Question
Why do some scuba divers hate some scuba innovations that can give rise to a higher degree of safety?

Example: the air-integrated computer with audible warning when you pass your user-determined "reserve gas" pressure.

I don't hate scuba innovations and I particularly don't hate AI computers. Everyone I know dives with AI computers so I can't even speak to the question based on discussion with them. The Question doesn't relate to me!

2) The responses.

Some who use AI Computers may be reluctant to state the fact to avoid being labeled lazy, complacent etc.

I dive with a AI computer with a group of competent divers who are not lazy. complacent divers lacking in dive skills. I do not rely on my computer beeps to tell me when to end my dive, turn around or how fast I am ascending. I determine long my dive will be based on my SAC, tank pressure, depth and surface conditions for the exit.

I do know that when narked I tend to get tunnel vision. I don't rely on my computer but IMHO it is a good thing that if I ever am narked I have an audible device to get my attention or that of my buddy (if I am too narked to notice it).

Back in the 80's the auto industry tried digital instrument panels but got push back from buyers. Besides the unconventional look they required a conscious effort to read the numbers instead of a quick scan that the needles of conventional gauges were all in the normal position.
I like a analog SPG and depth gauge for the same reason. The best dive computer display is the original Edge that came out in 1984. It has an easy to scan bar graft display that doesn't require reading numbers.

I have to agree with you there. I much prefer a "dial" to "digital" in that I can see where things sit relative to the whole dial - it requires a simple glance at the dial.

Regarding graphs, when I teach OW students with computers, I discuss the nitrogen loading bars (or O2 depending) on computers and how to "use" those.

Many years ago I went to a "safety day" hosted by Phantom pilots at a US airfield in England. They wanted to show local private pilots what issues fast jet pilots faced. Key to this was information absorption. They said that it had been found by tests on US military pilots that they absorbed information from an analogue scale seven times more quickly than from a digital one.

I carry lots of safety innovations with me when I dive such as:

• an SPG, so I can see how much air i have
• A second regulator so my buddy can breath off my tank without us having to share regulators
• A BCD so I can gain positive buoyancy in an emergency without having to drop weights

There was a time when all of that was considered unnecessary and in some instances dangerous. Nowadays I would say for recreational diving that's all pretty much essential safety kit and I imagine most people would agree. Its not that people don't like new safety advances its that for every bit of safety kit you have to look at it and decide if its necessary and if it actually does make you safer. For me an AI computer isnt necessary and would not improve my safety any so i don't use one.
