I hate AI, especially wireless but I hate Suunto's wireless more than anyone elses. I've never had a buddy with a problem with a Uwatec but I've had 3 buddies with Suunto's (Vytecs and D9's) and I've turned on and off their valves for them while they tried to get their transmitters to sync.

Great computer, almost as great as the venerable Nitek 3 :)

Ok, lets do the math (I'm bored).. can a steel tank rust enough to get the O2 down from 21% to 18% assuming a 3000 psi fill in a 12 L tank (AL80 sized)? Lets assume that a steel tank is made up of 100% iron. Rusting is as follows: 2 Fe + 1.5 O2 -> Fe2O3. Now we need to know how much O2 needs...

It will be just fine for cavern but you'll probably want to replace it before you go into doubles.

$50.01 :) Sorry, couldn't resist.

Well that makes sense.. but I'm sure Hal Watts has at least thought about it :)

You're crazy if you don't take the ferry over to the mainland and do some cave dives (or at least a guided cenote dive if you don't want to mess with all the extra gear). They will blow you away. Real easy to setup and I think the guide will meet your ferry.

Did people (or perhaps just Hal Watts :) ) ever dive hypoxic nitrox mixes to get the ppO2 down? I guess the increase in the narcotic effect would be fairly minor (going from 79% N2 to say 85% N2) compared to the increased MOD of the O2. Of course if your maximum acceptable ppO2 is 2.0 (I...

Wouldn't it be great if we did it like the Europeans and just talked about liquid volume (e.g. a 12 L tank or a 15 L tank).. sure does make it easier to compare absolute sizes. And if we switched to bar's instead of PSI, figuring out how many liters of gas is in the tank is trivial.. a 12 L...

When you say a traditional hose computer are you referring to an air integrated computer that has a hose such as a Suunto Cobra or are you referring to a computer that's in a console with a seperate pressure guage? Here is what I like and why: I like the computer to be on my wrist so it is...

I know several people with D9's - my former LDS used to push them. I've seen all of them have trouble with their transmitters on the surface before the dive. I think it's just a Suunto thing, never seen anyone with a Uwatec have an issue. Anyway, the first thing you need to backup (or just...

The only difference in the segmented method and a single class is that with a single class an unprepared diver is never placed in OW and not many OW divers go on to rescue. I think 99% of the time the lack of training in OW results in two things: the under trained diver drops out because they...

For the discerning diver who wants redundancy that just won't quit I recommend this: Rig yourself a harness with about 60 loops on it all over the thing. On these 60 loops, attach 60 spare-airs. When a spare-air is empty, replace it upside down so you don't accidentally grab it later. Now...

All you need to figure your SAC is your average depth, time and volume used. SAC = volume used / (pressure-at-avg-depth * time). Knowing those 3 numbers (which the Vyper will record for you), you can calculate your SAC over the entirity of the dive. I believe that's what Suunto meant. Now a...

Not a double chance of failure but a double failure - your redundant systems failing after your (or your buddy's) primary systems fail. Independent doubles are two tanks not manifolded together.. the only way it works is with two first stages. No, it is exactly the same. If I am diving...

I disagree with Mike S here. Needing both your octo and your pony implies a double failure (what are the chances of your buddy running out of air and then you having a failure during your ascent or having a leak in your pony bad enough to empty it that no one notices and your buddy going OOA?)...

Here are some tank specifications, pretty much every tank you can buy is listed here: http://www.techdivinglimited.com/pub/tanks.html

You'd be quite dead. Without getting into gas planning rules, typically you will surface with *at least* 500 psi. Most people consider gas below that to be last-ditch emergency reserve. Most regs will require the tank to have at say 80 - 120 psi in the tank over ambient pressure to work worth...

About 6700'.. most tanks are rated to 3000 psi, air is 14.7 psi, every 33' of seawater exerts 14.7 psi of pressure.
