I am really curious - How many of you out there are diving with Nitrox?

Depends on if I'm doing repetative dives and what their profiles are. It definately has its uses and if you're thinking about getting certified EAN, I'd so go for it if you plan on doing any multi-day repetative diving.

not yet, my sac rate is so bad I can't stay down long enough to get into trouble...lol

thanks!
I just got certified last weekend, for exactly that reason!
---that's what sparked my curiosity, and made me want to post the poll!

As often as the dive profile calls for it... if I'm on a boat that offers it, almost always. Local shore dives, however, rarely.

I would dive it all the time if I had access to a local shop that offered the monthly all-you-can-eat Nitrox plans, like some places in the PNW and San Diego, but with the amount of shallow (under 45') shore dives I do, I'd go broke diving it all the time for every dive!

My EAN fills run ~$5.60 each (sold by the cubic foot). At that price I can't see a reason not to dive EAN. The cheapest air fills in the area are $2 each.

All the time, as long as my banker allows.

I can get a Nitrox card that will give me $8 fills, but no one in SoCal sells by the cf. Definitely jealous of that feature in Florida. Cheapest air fills are either free or $2.

Given a choice between free (or $2) and $8 for a fill, when I'm doing a dive that puts me into the sand at 40 fsw, I see no reason to waste money on Nitrox.

Deeper shore dives, however, I will sometimes spring for Nitrox, and sometimes just dive air. Most of the boats I take offer Nitrox, usually $20 for the day (3-4 dives), and I almost always take advantage of that, since boat dives tend to be in the 60-80'+ range, so it's definitely worth it.

Nitrox around here runs from 10.00 to 14.00 per tank depending on where you get it and air is 5.00 to 7.00 per tank unless you buy a 30.00 air card then it is 3.00 per fill for air.

We travel to dive so when we travel we dive a LOT! We finally got nitrox certified earlier this year and saw what a huge advantage it is for folks like us who do a lot of repetitive diving in a short time. We typically dive between the air and nitrox tables when diving nitrox to try to get both the best of the safety and extra bottom time. So if we can get nitrox, we use it.

I dive Nitrox EANx21 constantly. Does that count?

Its expensive here - $10 a fill. But it’s the best thing since sliced bread and underwear. At 50’ I’ll always run out of gas before I hit the NDL.

I use it on about 60% of my dives. Many times I'll do a deep dive on nitrox with my 120, then a shallow dive. If I have enough gas left in my 120 I use it, so that shallow dive is also on nitrox. But If I'm planning a shallow dive, then I use air.

Dive it when ever I can (which is most of the time). All the time on vacation (Well anything but air if available).

Bring it on! We've got full rental cylinders at the shop just waiting! I'm headed out this weekend too.

Maybe I'll see you out there,

Always.
I have my own tanks, so they are always full and ready for me to go on the fly.

I used to keep 1 steel filled with 32 and the other with 38.

The folks I dive with now, 36 usually works, so that's where I keep them all.

Have not been certified, but I committed to doing it before I head to the Bahamas for a liveaboard at the end of the year.

Not certified yet-probably next year. I want to make sure I get it done before going on a dive vacation so I can do more divers per day.

When I calculate the difference between my depth usage, and SAC rate I don't find any benifit. Maybe when I build up a much larger # of dives and get low enough in may SAC will there be a benifit, but on an AL80, I would have to do 4 dives in one day.

For trips where multiple dives dives are the norm, then it makes sense to do it. Especially after seeing the effects of DCS. Why take the chance?

I dive Nitrox almost exclusively - even beach dives. In the interest of full disclosure, I should add that my LDS banks 32/36/40 and the cost is the same as air.

I'm surprised no one has started the debate about feeling less post dive fatigue on Nitrox. It's not a substitue for a nice SLOW ascent but I believe it does help with fatigue. I also like the added safety margin from reduced nitrogen loads.

If i'm gonna be near a limit, i'll use nitrox otherwise I save my money and use air. I think the whole air vs. nitrox and fatigue was debated in another thread. Personally never felt any diff.

I dive nitrox on dive trips and live aboards and just about anywhere I plan on multiple days of multiple dives.
But just going out to CSSP to check out some gear or practice skills...nahhh

Doesn't make a difference for me, and we "tested" the less fatigue theory on a liveaboard diving 4-5x a day. However, if it works for some, bravo for them.

Sometimes - not locally, but all week on last trip aboard the Turks & Caicos Aggressor. There were only 2 people not diving Nitrox and both got their certification during the trip.

Only when using it for a DECO gas.....or an occassional FG trip.

Always unless I am going deeper than 100' then its triox

When I'm in town and diving shollow its air. When I get down to cave land It's alway's nitrox to get the most diving I can get in. Doing wreck's in the 80' to 130 range I use 28% to 40% (dive specific)

I dive Nitrox most of the time, but right now I'm back to using air because I'm diving locally more than down south at the lake where it's available.

I do lots of live aboards and nitrox is the only way to go when doing multi day, multi dives. On the Peter Hughes boats if you dive in consective years you only have to pay for nitrox once. Just don't miss a year though or you have to pay again. My last Peter Hughes trip was Jan of 2006 to Belize. I'm doing the Star Dancer in PNG in October. Woo-hoo free nitrox. Now I just have to plan one for 2008.

I do not dive WITH Nitrox, I dive WITH my buddy but I USE Nitrox as a breathing gas.

No Nitrox here. Tough to find aplace and get the fill.

Xspect
08-27-2007, 11:56
I had the option this weekend.

Dive in a quarry all weekend or take a non-dive nitrox class

I'll let you guys guess which one I chose.

tnfireman
08-27-2007, 21:16
I'll dive it if the dive profiles warrant it or doing multiple dives for consecutive days. Most of the time it's not worth the cost for me.

Not yet, but someday probably. Seems like a good thing to do, it is just a question of $$$ and priorities.

Planning on it. Hopefully this winter sometime. It is going to be a Christmas present to myself. I am going to try and get the cert with Scuba toys. Seems like a good excuse as any to make a little road trip and since the class is only one day it is reasonable to do such. I would like to make it down there, see the store, meet Joe and Larry and get a little more edumacated in the process.

Someone else said it before...it's kinda expensive at around $10 per fill (it's actually a little higher since the US dollar weak in PNG) but longer bottom time seems to be worth it. I'm usually the only one using it on the weekends....maybe I'll negotiate something with the dive shop.

I envy that guy who is paying $2-$5 for that Nitrox fill....where do you go? Are you filling it from a gas company? (the post from Ft. Lauderdale?)

How much are you guys paying for tri-mix?

RoadRacer1978
10-14-2007, 15:58
Wow, $2-$5 for a nitrox fill. Thats unbelivable. I pay $5 just for regualr old air. I think Nitrox is about $7 - $10, but haven't gotten a fill of it, so can't say for sure. Who wouldn't be diving Nitrox if they could get a fill for $2-$5.

thanks for the great laugh!! I'm a nurse and I talk to people about their need for oxygen. some are afraid of becoming "dependent" on oxygen....duh.....ALL HUMANS are DEPENDENT on oxygen. we can't breathe spaghetti!!

Boris and I have our class tomorrow - 10/15 and we are wreck diving on 10/27 and 10/28. Not sure how much we will dive it in the future so I didn't vote on the poll

Nitrox is $.07 per cubic foot (~$5.60 for an AL 80) at Fill Express in Pompano, FL.

10-14-2007, 21:26
My Lds banks 32/36 ean and will custom blend for $6/tank only if you have taken advanced classes with him. so why dive elevated nitrogen levels when you have eanx, he also does Trimix for around $10/tank if I remember right but I havent advanced that far yet

Depends. When I dive the local quarry no. When I go on the liveaboard trip in a few weeks yes.

I don't bother with Nitrox for dives at the local quarry but I would for a dive trip.

CompuDude

I wish more places sold Nitrox by the cf. I'm only aware of Fill Express in Florida doing that. No place local to SoCal does it, that I'm aware of.

bversteegh
10-15-2007, 20:37
Only for repetitive dives - I haven't noticed anything different in the fatigue debate; but do like the longer bottom times on a 2nd/3rd dive of the day.
