1.45 PPO2 VS 1.52 PPO2 Easter Egg Explained

Great info as usual, just curious why don't you include /use /report NAUI dive tables on your white board.

[@LakeHickoryScuba]

The only real reason we didn't include the NAUI tables, is because I don't have a set to include. I would be happy to include a set if I had them. NAUI is a great organization, and one of the oldest.

I recently switched over to a backplate and wing setup purely for the fit aspect (5'9 for about 130 pounds, even an extra small BC waist strap would not cinch down far enough to keep the tank stable) with a steel plate that takes care of my weighting. However I kept a classic "open-water" regulator setup as my dive buddy is used to this and I am not interested in taking DIR/tech classes at this time. I'm getting a ton of crap for this on boats, especially from DMs calling me a wannabe techie etc. Now I understand the appeal of streamlining and a tech philosophy or whatever but do you think its fair the way I have it or should I not have jumped into a backplate without associated DIR training? It has certainly been night and day in terms of no longer feeling the tank slip to one side or another and causing me to roll over unexpectedly.

Diving Philosophy can be a good thing and a bad thing. On one hand, most philosophies are good because they teach consistency and redundancy. However they neglect individuality and practicality. With this being said, I don't see any issue with your current set up. You will always have some one tell you that you are doing something wrong, or that you are a tech wanna be. This is how I deal with someone like that. I smile at them and say "Happy Diving." Then I jump in the water and go diving, and enjoy life. The great thing about being underwater is, you can't hear anyone complain. All I here is bubble, bubble, bubble.

It almost works out if you extrapolate SSI values of 106 feet with PPO2 1.52 and factoring in 100 , you get 1.43.

Sometimes math is like a magic trick. You can sometimes manipulate the numbers.

I just ran across this video and it's great to review the math but honestly, what recreational divers today actually use tables? I don't know of any. We just use dive computers. As I said, it's good to understand the math behind it but realistically, I haven't used a table in over 15 years.

Hello Andy Deitscch, a lot of divers share your view in the matter.

[@GlamazonBarbie]

I don't think it is SSI vs other agencies. You were using a table and you proved that ppgas = P X fgas. I'm kinda confused as to the point of this video.

This was response video to the series we produced on dive planning. It was meant to show that sometimes we have to make a decision between following The Tables, The Math, or The Computer. At the end of the day, all 3 are conservative in nature, and probably doesn't make that big of a difference when planning dives. Thus the less a diver worries about making the dive too technical during the planning stage, the more time he can enjoy underwater, enjoying the dive. This is very common for us, since we train through multiple agencies, and usually have students from different agencies all taking the same course at the same time. Just last week, I had a PADI Open Water Student, a PDIC Open Water Student, and 2 SSI Open Water Students all doing check out dives at the same time. Before each dive, we had all 4 plan their dives using the tables (from the respected agency), and we asked what was their maximum bottom time. The all had different answers. We then had them choose which plan would work for all 4. Once they decided, then we had them all plan the dive using their computers, for which they were all using different types of computers, and once again they all had different maximum bottom times. So they had to decide yet again which one to follow. Once they all agreed on which plan they wanted to go with, then we proceeded with their dives.
