Thanks for the quick response.   I really appreciated the opportunity to do the course entirely online. I took a Nitrox course on a liveaboard about 3 years ago. I did 20-some dives on Nitrox, but never got around to sending in the necessary paperwork to get the card.  I've got a dive vacation coming up in October and figured your course would be a good review of the material, as well as provide me with the necessary nitrox certification card. It turns out to have been a far more comprehensive course than the traditional course I took on the liveaboard.

The course was exactly what I needed!  I had forgotten the basic concepts.  Thanks for your knowledge.  My wife and I went to Bonaire where we were able to use nitrox for the first time.  What a difference.

I have to admit, I was a bit skeptical of the course because of the price.  Your price is considerably lower than all the others.  After taking the course, I realized what a great deal this was.  I will recommend the site to all of my friends.  The "recommended shops" page was very helpful.  Thanks

You're the BEST!  This online course was structured well, and extremely easy to understand but didn't cut any corners whatsoever.  I will recommend it to all my dive buddies who aren't yet Nitrox certified.  Thanks again!
