Rental equipment quality

[blue steal]

I needed to rent gear one time in Coz. The price was pretty reasonable, but since I had booked a package of dives they waived the rental price.
That was nice. I think you can ask if you book x amount of dives and get the gear either free or at a discount.
Oh and the equipment was in decent shape.

Depending upon when you leave, the one hour drive to a scuba shop may be a better option to practice skills than renting a tank in Cozumel and possibly being in water that you cannot stand in.

There is an advantage to being able to be in the shallow end of a pool.

Blue Angel has a pool, too.

Thanks everybody. The pool where we did the first part of our certification is more than an hour away.

This is embarrassing to admit but I bolted to the surface the first time I was supposed to do it, on our first day in the pool. We were all swimming around in the pool, which we shared with a class getting swimming lessons. I managed to get way over under the swimmers without realizing it. When I did realize where I was I went full speed across the pool and back to our group. When I got there and surfaced, the swim coach had come over and started yelling at me that I had run into one of his swimmers and that I was going to die as a scuba diver. Seriously. I know damn well I didn't touch any swimmer but I was definitely over on their side where I shouldn't have been. I managed to bite my tongue and not say anything back, which is not normal for me.

So, I'm already breathing hard and then have an adrenaline rush on top of it. Thirty seconds later I descend and try to do the mask removal sitting on the bottom. I pretty much immediately sucked water in through my nose and start to cough. I tried for half a second to just cough through my regulator but that didn't feel right so I went straight up. The next day I did practice taking my mask off while sitting on the bottom of the deep end. It helped a lot with getting comfortable but I think I have some kind of psychological issue with it now.

So I just want to spend some more time doing it and get more comfortable in case my mask does get knocked off at some point. I also want to work on the manual BCD inflation while underwater some more. I can do it but don't feel like I'm very good at it.

Anyway, I know I'm not really talking about Cozumel here so I'll stop.

For what it's worth, I'd dive with you in a heartbeat if we were buddied up on a dive. I respect people who are honest about their diving anxieties, vs those who are new and just pretend (or think) that they are awesome and won't have problems. And there seem to be a lot of the latter. As for anxieties about your mask, one piece of advice: if there's ever someone else's fins near you, naturally people put their hands toward the fins, but instead just use a hand to secure your mask.

... doing all this in rental gear, while in Cozumel, hence this is on topic!

Go to page 11 of the ProPlus2 manual, read it for yourself

I have done so.

and then come back here and apologize to me.

I am so very sorry the educational system failed you so badly.

As you know from having read it, it says precisely what I said it did. Oceanic makes no claims there that they figure air consumption into bottom time.

Where exactly does it say that? I don't believe you.

Without consideration of the question, I would be hesitant to ever challenge Doc's facts. Ever....

Where exactly does it say that? I don't believe you.

Here is page 11 from the ProPlus manual.

The page clearly says in the first paragraph that the ProPlus displays a bar graph at the bottom that is a display of the air time remaining....based on current consumption rate. So if you keep breathing the same way, at the same depth, that is how much time you have left. Go deeper or breath harder/faster, you'll have less time; go shallower, you'll have more time.

The second paragraph describes the numbers in the middle of the screen: "Dive Time Remaining." there are three things than can limit your dive time: air available, N2 buildup, O2 buildup. Whichever of those is smaller will be displayed. So if you are fairly deep and breathing relaxed, You might (example) have 10 minutes left before your N2 limit (NDL), but 20 minutes of gas left, and 120 minutes of O2 time left. The display will then show 10 minutes. A shallower dive with less N2 biildup might instead show the amount of gas left, because N2 is no longer limiting your dive. In this case, the numerical display and the bar graph at the bottom would show the same number.

But your gas consumption is NOT used to calculate N2 buildup; that is a function of depth and time only. "Air time remaining" is NOT the same as "Dive time remaining." they mean different things and are calculated in different ways....but in some situations might be the same number.

The problem is you guys are saying different things without being clear on your terms. When mstevens says "bottom time" he means NDL, based on N2 buildup. You are interpreting that as "dive time," which is the Oceanic term for whichever is smallest of N2/Bottom time, air consumption-based gas left, and O2 buildup.
