A while ago I read a book on sharks by an expert (I don't have the book and don't remember the title or the author's name), who agreed with you. He said that sharks are curious animals and if so inclined will bite in order to taste with their gums to determine what the creature is and possiblly...

What I recommend all NDL divers do is set an alarm on your computer to notify you when your NDL is under 5 minutes. You can do this on the Perdix. A visual reminder is good but in addition a vibrating warning is best if you get distracted and don't look at your computer.

So, I confused surface interval with half-time. I must be watching too much football. You posted this information in another thread. I should of looked it up first before posting but I got lazy.

No. This is wrong. The PADI tables, I believe, are based only on one tissue compartment with a half-time of 120 minutes. Dive computers using ZHL-16C incorporate 16 tissue compartments with varying half-times of which any one compartment can be in control of the dive based on the dive profile...

Based on @rddvet and the above response I feel I might have been misunderstood. I am not criticizing anyone for getting bent. I was simply pointing out that saying something negative regarding something you are trying to persuade someone about works against you. Paraphrasing @oya, "I believe...

I'm sorry you had to go through so much trouble before finally finding the cause, but what has this got to do with my comment specifically, and what we're discussing in this thread in general? The question is whether average depth and/or the modified rule of 130 is safer as a backup to diving...

It looks like he's breathing from a tube extending up from the goat bag. If that's the case, why is he breathing from a bag if he is just floating on the surface?

Yeah. I did the same thing with my Perdix. Playing with it, while not giving you much understanding (until you read the manual), at least you know where the settings are and how to go through the various menus.

...and let's not forget what videos on u-tube can provide. As an engineer I'm pretty good at understanding technical documents but Shearwater's explanation of the tissue compartment inert gas graph left me wondering. I found Shearwater's video about the graph and watching it solidified my...

Ummm......this does not give us any confidence for your average depth and/or modified rule of 130. I simply don't understand why anyone would bother with any of this while diving, and unless you don't have access to your computer or tables to do some pre-dive planning, what's the point?

I thought you always could do a timed safety stop in OC tec mode, but you had to start a timer manually which counted up like a stop watch.

For the Apollo space missions NASA designed a special pen which would allow writing with ink in low/no gravity conditions. I believe it cost thousands of dollars to develop and produce. When the Russians were asked how they solved the problem of writing in low/no gravity environments, they said...

I know this is just the basic scuba forum but geeeesh, have some respect! Don't tell me you're just jumping in the water without 3 gases, 3 dive plans, 2 computers, tables, wet notes, and oh before I forget, TTS prominently displayed on your DC! What are you thinking? :)

Why? For newbies it's good advice because their likely to go deeper than their buddy or worse, stray and loose their buddy. As an experienced diver I would dive my buddy's computer making sure I stay close and at the same depth or slightly shallower. If I was really concerned I'd come up to 30...

Should the title of this thread be "Are dive computers making safer divers"? How easy is it to jump rows or columns with tables and end up in a lower group? Yeah, I know. You can enter the wrong gas or conservatism factor in your DC but if you're that challenged maybe diving is not for you.

@bfw your reply is a little too cynical for me and certainly did not represent what the dive shop I supported did. Once (and sometimes twice) a month they encouraged new and experienced divers to meet with them (instructors and DM's) at the local quarry for some "fun" dives. It was a chance for...

I would not add any arbitrary deep stops. My advice to you is to follow your dive computer whether it includes deep stops or not. If your DC calls for a deep stop some slower tissues will on gas more nitrogen than if you were to make a continuous ascent to the safety stop. But, so what! What...

OK. I understand what you're talking about. Once the dive computer (DC) counts the NDL time remaining to zero the DC will start calculating the time needed in minutes at the shallowest deco stop, and you are at that point making a deco dive. The DC after some short delay will then show your stop...

The Wikpedia article on ICD includes cases where gas switches were made going from helium mixtures to nitrox and vice-versa. It also talks about the specific causes of inner ear DCS and skin bends due to breathing nitrox while the skin is surrounded by a helium mix. Here is the link for your...

It does? Invalid for what?
