And by "worth it" I mean, in your opinion, what type of diving (frequency, etc) is Nitrox a benefit, etc. I've done a little research into this and figured as part of that research I might as well ask for opinions here amongst veteran divers and those who have used Nitrox. My wife and I are going to take our first trip to Bonaire this January. Super excited by the way. We are both experienced divers but have never felt we had the "need" for Nitrox certification since we've mostly done boat dives with charters or on our own and seldom dive deep, preferring longer bottom times.

As soon as we told our local people here we were going to Bonaire, the first thing they said is, "You should get Nitrox certified." They explained, and I found through my research, the benefits of shortened surface interval times and all that, which I understand. But really, my question is this, "How much diving do you need to be doing to NEED the shortened interval times? And to what extent is it worth the cost to certify, etc.?" I guess I'm trying to weigh the realistic amount of diving frequency while we're there with the cost of $300 bucks to get us both certified before we go. Realistically, I see us doing a couple dives before lunch each day, having a surface interval that involves stopping somewhere to eat and taking our time there, then doing one or two in the afternoon (depending on if we feel like hanging out at the pool or not, haha), including a couple of night dives while we're there. We'll be diving for 6 days. I know each person's dive profile and all that factor into the equation, but the sites there are pretty set in relative depth, etc and most people I would guess would have similar profiles for reef/shore diving there. Any thoughts are appreciated. Thank you!
 
EAN is beneficial in that it's a little bit safer to dive than air (dependent on depth) due to decreased nitrogen on-loading. Some people say they feel less fatigued on EAN after several days of diving than they do on air. I myself have yet to experience that. I've also been told that diving EAN is a good option if you get headaches. I got a nasty headache after my first dive one morning in Cozumel back in August and decided to not make the second dive. That headache was pretty debilitating and even made me a bit nauseous. I was told later that I'd have felt better had I switched to EAN. Not sure how much truth there is to that but increased oxygen intake to curb a headache sort of seems like it makes sense. But the main benefits to diving EAN are increased NDLs and shorter surface intervals. Whereas diving air might limit you to 4 dives a day, EAN could allow an additional due to short surface intervals. It then sort of becomes a question of monetary. Is it worth not only the cost to get certified to dive EAN worth it, but it the additional cost per tank worth it.
 
If you end up being limited by your NDL and not your gas, and wish you had more time diving, I would consider nitrox certification. This takes into consideration your profiles, repetitive dives, and surface intervals

Now that is a short sweet to the point all encompassing response - that should be pinned somewhere
 
Honestly there is NO downside to having your Nitrox certification. You will use it. If you're only doing 2 dives a day... maybe it's not all that important. 4 a day, definitely.

Nitrox is really becoming the recreational dive gas. There are dive operators and boats that are now "Nitrox Only." They just don't do air anymore. I just got back from Grenada and the op there recently removed their surcharge for Nitrox. It's the same price as air. The owner told me after the 1st of the year, he was going to add a surcharge to air instead in an effort to eliminate it from his business.

The certification is inexpensive and well worth it.

Maybe ask the shop you are diving with if they will certify you - you can do the course online and knowledge review and tank test at the shop when you arrive. Realize there are hard costs in that or any class - whatever the certification agency charges.
 
Nitrox will give you longer NDLs, especially in the 60-100 feet range. If you don't get close to your NDLs diving air, the only real benefit to diving nitrox is the shorter surface intervals. If you are boat diving, it won't matter as everyone will have the same intervals.
There is no magic elixir in nitrox. Some people believe the placebo effect. Some are more realistic. Headaches indicate improper breathing underwater. Skip breathing and fast ascents cause headaches. Relax, slow your ascent WAY down and you will feel better no matter what gas you are breathing.
If you find yourself reaching your NDL and wish to extend your bottom times, nitrox will help that.
