I am considering certifying to dive with Nitrox. I am a warm water recreational diver who is now retired and planning on doing more diving. Most of my diving thus far is during week long dive trips to several different Caribbean islands. Is there really enough benefit gained by a diver like me certifying Nitrox?
Also I noticed I can get certified just by doing an online course. Is this OK, advisable or is there significant advantage to taking the course at a LDS? WHat are the typical costs of such courses. The one I saw for online cert was listed at $89.95 USD.
You're kidding? Of course nitox certificaiton is advantageous. Online certification and analyzing in a shop makes this simple. We used to have to take a relatively rigorous exam and make 2 dives. No brainer.
Sorry, I posted this based on your original post without reading the intervening messages. The feel good message is essentially bull****. You dive to the same exent of NDL(longer) and feel the same (just fine after diving). The big advantage is the longer dives. Incredibly more dives time over multiple dive, multiple days.
