Tbone, Can you elaborate a little. What do you mean by model? Do you have computer codes for specific mathematical models? It would be nice if all dive computer manufacturers were required to publish their deco algorithms in open-source format. Maybe I should do a Kickstarter project for an...

Hello All, Recently I purchased a new dive computer. On the first few dives I compared it with some of my old computors for sensor accuracy and NDL. New Computer: Oceanic Veo 2.0 set to the DSAT algorith, air and no conservatism factor. Previous Computer: Cressi Archimede set to air and no...

I think this is very commonly done with Suunto computers. The least conservative setting on them is still very very conservative. If you dive on air you will tempted to use this technique to be compatible with your group. It seems like a mathematically valid way to get normal conservatism out...

How did you resolve this?

Thanks for all the well thought out responses to this thread. It has been a lot of fun.

The mathematics behind dive computer algorithms is really pretty simple. Manufacturers layer on marketing mumbo jumbo but they all do pretty much the same thing. The most important difference that affects the diver is relative conservatism. Except for a very few lab tests and word of mouth...

Tortuga, I have to agree with your assessment about Suunto computers. My experience was with the Suunto Mosquito and I found it made diving on air almost impractical. I prefer a computer I can be set to medium conservatism. That has worked out for me over quite a few dives. I guess every diver...

I found some scubalabs comparisons of mainstream computers here: Gear / Accessories | Scuba Diving less conservative - Aeris, Oceanic, Sherwood more conservative - Cressi, Suunto, Mares

I'm looking for info about the relative conservatism of the major brands of dive computers.

Hello All, Has anyone seen a recent comparison of dive computer manufacturers with respect to minimum conservatism? Pete

My experience tells me that once a computer give you a reliability problem, discard it and get a new one. I bought an early Cressi Archimede 1 dive computer because I liked the user interface and it was not too conservative. On my first dive with it I had a small battery compartment leak in...

I think many of the responders here give dive computers too much credit. Also, there is a lot of promotional information published about new algorithms and the new computers based on them. It is not unusual for a diver to test his/her new dive computer next to their old computer, at least...

Many people dive nitrox with their computer set to air to get more conservatism. This guy set his computer to nitrox and dove air to get less conservatism. Pay your money and take your chances. Actually, in this case he was diving with two computers. His old computer was set to air like...

Thanks for your replies. It sounds like this is an almost completely novel response to conservatism creep in newer computers. In this particular case, the diver was very experienced and in good health. He was diving every day on air. Conditions were warm water, good visibility and no current...

A common complaint I hear is that newer dive computers are overly conservative. The reason given is that computer manufacturers are afraid of litigation. I encountered one diver who had adapted to the problem by setting his new computer to a few percent of enriched oxygen. He could test the...

Axxel, Thanks, that sounds like a good way to do it. Next time I'll try your way.

Bubble, I had this problem of a slow leak where the quick disconnect of the air supply hose slides onto the inflator assembly. It looked like some very fine grains of sand got under that size 011 o-ring inside the quick disconnect. It was very time consuming and frustrating to remove and...

On most recreational dive boats it is the boat staff that handle setting up tanks and tightening the cam bands. Also, very few operations have the space to pull the rig off onto the deck and wrestle with it as you suggest. This situation happens to everyone eventually. The original poster...

It took me a few dives to figure out that I needed to have my ears above my heart to equalize. A great many people are like that. I don't think it has anything to do with technique, just how your ears are constructed. :cool2:

Thank you for the story. I had something very similar happen to me in a cave in Mexico. It was my 15th dive and I did not understand that I had to be vertical to equalize my ears. The divemaster emphasized that we should stay horizontal to avoid kicking up sediment. Anyway, he ended up...
