Why do computers rot the brain?

But Uncle what happen if all the lights ( principals and back ups) of me and my buddy dies ?

if I have a puter I can always go up slowly (but since is all dark I have to guess) and I'm sure if I hear bip bip I have to slow down, so I can reach the light in a "sure" way...
What would you do in a such case ?

...I accept the challenge.

But lets both play by the same rules.

If all my lights go out yours do too.

And your computer beeps and tells you that you are ascending too fast so you dump air from your BC and/or drysuit... and you begin to sink and your computer stops beeping... but how do you know how far and how fast you are descending.... your ears begin to get tight... do you equalize them?.... they are starting to hurt... do you equalize them? Do you add air to your BC? Your suit is squeezing you... do you add air to your suit?

My lights go out... but because I've practiced hovering with my eyes closed it isn't a big problem for me to keep my stop... and then ascend slowly to the next one listening to my ears and feeling my suit get a little looser I vent from the suit and maybe dump just a touch from the wing... and stabilize at my new stop... and repeat to the surface.

Would you like to get together for a night dive lights out test?

Does anyone else see the irony of quoting the experts on why you should not use a computer because it can lead to dependency and limits flexability?

Why do you call it ironic?

Scott,

It was a rhetorical question, it’s like the ad for the Washington Post: “If you don’t get it, you don’t get it.

I think you missed something. The question may have been rhetorical, but that's fine. No one answered it.

However, in the question you stated that you found something ironic, and Scott was wondering what was ironic about it.

The funny thing is that everyone probably understands both points, and those that think it's ironic are sorely misinformed about something. There were some other recent threads you may wish to check out.

Well what did I miss? Unless you’re implying that that too is rhetorical, in which case it would be obvious, and hence an explanation would be paramount to explaining the punch line to a joke.

What’s funny about everyone understanding both points? And what are the points that everyone understands? And what exactly is your point?

The point of my rhetorical question, was the irony of blindly excepting the concept of not using a computer because somehow the availability of information compromised your ability to think for yourself, because an “expert” provided that information; rather than making an informed decision on your own.

You are confused here Mike.

We all learn from others and listening to those who truly are experts in their field is a wise move. It does not replace thinking but actually promotes thinking as we evaluate what they have to say and make our choices accordingly.

Dive computers do not necessarily make more information available to you... in fact they obscure useful information and prominently display *NDL Time Remaining*.

They also tend to cause folks to pay attention to that one prominent number and ignore other environmental cues...

they short circuit the thinking process.

You are only kidding yourself if you think that your computer helps you think for yourself and make decisions on your own.

I prefer to have Bottom Time and Depth prominently displayed. From these I can discern everything else I need to know.

The bottom line is you should dive with what ever you are comfortable with, I do find it strange that DIR does not reconize the advantages of computers, but so what, dive tables work well even if they are very limited.

I have a couple of questions for PUG or any other table user.

in my example we will use a dive to 200 feet requiring a long deco profile.

1 - what if your profile changes dramaticly durring the dive. say your bottom time doubles or your depth becomes deeper by say 40 feet. obviously this is due to some sort of unexpected situation.

2 - What about exploration, say a wreck dive or any dive where your acual profile will vary throughout the dive.

I am obviously asking these questions because i think computers offer a great advantage here. it is not to set you up, it is to understand your/DIR's view pionts on how tables can have the advantage.

A discussion of how and why DIR divers do technical dives without a computer is not germane to this thread.... (that plus the fact that this is not the technical forum.)

However it would be a good question for you to ask in the Technical forum and see if you can get any takers.

I thought this was a thread on the advantages vs disadvantages of tables and computers.

if it makes it better fit this thread. make the dive 100 feet for 20 minutes with no planned deco requirment

ps under the computer section are we only allowed to discuss rec diving. i use a computer for tech diving and feel this is a spot for any subject relating to computers

I think a lot of divers get confused by this point. The reality is that the sort of tables you can get from training agencies or most dive planning software are no better than a dive computer. Usually the only benefit to using tables is that forces you to pay more attention to what you're doing. We frequently get new DIR wannabes telling other divers to switch from computers to tables and I'm not surprised they meet with such resistance.

The optimal solution is to learn how decompression actually works and throw the tables away. I don't use a computer and haven't carried tables with me for years. Just memorize a few simple rules of thumb and then you can apply them as needed to come up with an approximately correct ascent profile. The results are better in every way.
