The package is an educational system that includes: See what a big impact the extra bottom time has on surface interval time? If your Naui dive tables is less than 10 minutes, you must consider your second dive as a continuation of the first dive. That is where the ” Letter Groups ” come in. Dives to less than 40 feet depth are treated as 40 foor dives Do not naui dive tables faster than 30 feet per minute To maximize dive time, start with the deppest dive, and then make each repetitive dive shallower than the prior one.

Please note that due to differing screen resolutions and color depths, not everyone will see the data equally clearly. For most divers, yes, they have replaced the tables. For example, if you naui dive tables a dive to 18 meters 60 feet for 22 minutes, the 22 minutes rounds to 25 minutes.

Nai letter A represents a small amount of nitrogen and the amount of nitrogen increases as the letters progress towards L.

Residual nitrogen after a dive See, the problem is that while science has determined that it is safe to ascend from 60 feet after 35 minutes — “safe” meaning that nitrogen gets released at a sufficiently slow rate so as not to pose a danger — it does NOT mean ALL the nitrogen that was absorbed into your body down there was released during ascent.

So on your second dive to 50 feet, you naui dive tables have as much nitrogen in your system as you’d absorb naui dive tables 31 minutes down there. And since dive computers record your actual descent and the actual depths you stay at, their data is more accurate and give you more bottom time in multi-level diving than dive tables which assume you stay at the deepest depth the entire time.


Some don’t even need a pressure hose and get the data via a naui dive tables transmitter instead. Obviously, the longer you wait, the more of the extra nitrogen your body absorbed during the naui dive tables dive gets released.

So the total nitrogen is as if you’d stayed down there for 76 minutes, naui dive tables 76 minutes your Total Nitrogen Time and you are in End-of-Dive Letter Group J.

Anytime an ending pressure group is Y or Zall following surface intervals must be three hours.

The blade is treated for rust prevention. With degree views the ST Full Face Snorkel Mask naui dive tables you with the best field of view with the added safety guarantee of shatterproof window.

My suggestion is to use and understand one set of tables and stick with them. How long would you have to wait on the surface? It takes less than 1 business da. It essentially tells you how much nitrogen leaves your body over the time you spend on the surface, sitting on the deck of the dive boat.

Let’s say you do that first 35 dice 60 foot dive, ending up in Pressure Group N, and then want to see dibe dive hables that’s 50 feet down and you’d like to explore for 40 minutes.

When you unscrew the cap, pressure is suddenly reduced and the soda foams as carbonation is released. You find that your surface interval needs to be just minutes. Letter Group — As expained above, for repetitive dive planning purposes it represents the “Letter Group” of the amount of nitrogen that remains in your body after a dive.

Flip the card and see where your current Pressure Group, row N,intersects with naui dive tables Pressure Group you’ll be in after that second dive, L.
