Whats next?

Thanks for the input. I was leaning toward the AOW anyways just because I felt like that would be the more benficial. It's just that you are always hearing people praise the nitrox and how much it helps. But definately thanks for the input.

You still breath the same amount of gas, wether it be normal air or nitrox. And when you breath that same amount down to 500lbs or whatever it is you turn back on, then you're done.


The advantage of nitrox is, it gives you longer bottoms times. Remember your tables from OW class that said at X amount of feet you can stay for Y amount of minutes before you need to decompress? Using nitrox lets you use a different set of tables so at X amount of feet, you can stay for a longer Y amount of minutes than you could with air. Surface intervals are shorter too.

So... where nitrox is an advantage is when you're going to a 100 feet and want to stay for longer than a few minutes, and will have more than enough gas in your tank to do so. It's also good for dive trips where you do a bunch of repetitive dives, as if you recall from those tables from your OW, the more consecutive dives you do, the less deep for less amount of time you can go... nitrox extends all those times giving you more time underwater at depth than air would, provided you have enough gas in your tank to do so.

The reason I am asking is because ME and my fiancee are going to the bahamas for our honeymoon in June and she is goign to get her open water certification before then.

With that added information just go dive while she is in class. That will get you freshened up and slightly more experieinced for when you are her buddy post certifcation.

When you are both ready you can do AOW etc together.

I called the instructor that I used and she is setup to go january 27th to start her classes and I am going to go with her for the dives.
