I would also add Tom's to that list. I've had only good experiences w/ their rental equipment (although, granted, it's been a long time since I've rented from anywhere in Texas), have trusted them to service my gear, and - like the other two shops mentioned - they've always treated me well.

I agree completely! I hardly ever get on Scubaboard anymore, just because it eats my time. But your question caught my eye. I always wonder about these things, and rarely think to ask before it's time to be tipping, and then it feels awkward (plus, I may not have brought enough money). I've...

I was thinking about: maintaining current cpr certification; taking care of and organizing rental equipment; filling and hauling tanks; completing paperwork (especially if there is an incident - any incident); learning enough about the area to answer specific questions; scouting out & planning...

One more thing to consider: Not only do DMs typically do work "behind the scenes" to help ensure that you have a safe/fun dive, but they also PAY for the honor in the form of liability insurance. That can be pretty costly. I think I get the McDonald's comparison, but the difference is that...

A geocache at 2300 meters???? :shocked2: Are sperm whales geocaching now? Shawn, it was nice to finally meet face to face! We had 3 great dives - temp and vis as reported... although, I think it might have been better than 5-6 feet in spots. And John is now certified!

I've heard more than a few people lately say that they've had "misunderstandings" like this. At some point in the dive, one person makes assumptions about the other that aren't necessarily true, or it becomes apparent that both (or all three) people aren't following the same protocol. Because...

Here's the article about it. http://www.gainesville.com/article/2..._Fathom_Grotto

You can also use this to do gas matching before the dive if you are diving with someone who has different size tanks. Once you figure out what volume each diver has, you can calculate turn pressure in your head more easily.

My experience has been that the dive shops I have been to in Austin have required tanks to be O2 cleaned every year b/f they will put Nitrox in them... well, at least 3 of them - the fourth, I may have just assumed it (Mack - does Oak Hill require cleaning every year?). I haven't had my tanks...

I really like nitrox when I'm on a liveaboard - especially some place like the Flower Gardens - or when I go to Florida, or somewhere else where I'm doing multiple dives a day in the 80-100 range over multiple days. I use it in those situations NOT so that I can decrease my surface interval nor...

Speaking for myself, and only myself, I WOULD dive 28% if that's what was in my tank, and if it didn't cost any more than air, and if I didn't have to pay extra to keep my tank/valves O2 clean, etc. But 28%, IMO, doesn't really have much added benefit over air. At 134 feet on 28% (which, yes...

I'm soooooo signing off now... I shouldn't have even gone there - so totally hijacked this thread - and the truth is... I don't trust any of 'em anymore. Too many years working with politicians and their minions... not many honest or straight-forward ones among the whole lot. Sigh... I wish...

OOOH! Politics!!! Now we can REALLY make fools of ou - oops, I mean, "have an intelligent discussion..." Anyone up for talking about Sarah Palin? Seems like an easy way of refuting my (joking) assertion about females being the more intelligent of the species...

OBVIOUSLY a reason why there should be more FEMALE technical divers. Y'all have the brawn; we have the brains... it's a good match. :blinking: (okay, for those of you who don't know me and are getting ready to flame me: I'M JOKING.)

Yeah... I just had that conversation (via email) with a friend - who has his own oil-free compressor - today. It's hard to know what to do when you want to take good -excellent - care of your equipment, but don't necessarily feel the need to go "overboard." For example, I have recently...

And, he backed away from that statement - or explained what he actually meant - with this statement "My point is if someone has an air test that shows clean air, that only means the air was clean at the time the test was done." Be careful before you go slapping that "L for loser" on your...

Yup, he does. Got the card and probably a lot more knowledge than is needed to get the cert. He's pretty anal that way (actually, if anyone DID have tanks that were 100% free of contaminents - even on the outside - it would be Dan...). What he actually watched in a dive shop was not people...

Umm.... and why do you assume he doesn't have the cert?

You mean, like this?? Sorry... couldn't resist... :10:

I'm having to cut one off of a set of double Al80s, and am having a hard time finding a replacement. Does anyone in the Austin area have one I can beg, buy, or steal? Or know where I can find one?
