    Contact Lenses vs Prescription Mask

    When deciding on what prescription to use underwater, it's useful to consider the optical qualities of the standard mask/water interface. There are a couple of ways to look at it, both having to do with the "closer & larger" phenomenon we learned back in the OW class - (1) "Infinity" underwater...

    We all make errors. Let’s not judge those involved without understanding the ‘how’ it made sense.

    Please see the Mishap analysis & "Blamestorming" sticky at the head of the A&I forum...

    Open-Ended Bans?

    @ Insta-Gator - it is appropriate for those whose time is taken by miscreants on the board to decide the fate of the miscreants. @ CuzzA - A democracy is two wolves and a sheep deciding on what's for dinner. FWIW, except in very rare cases of direct, intentional, gross violations of the TOS...

    My friend was talking about solo cave diving. Is this a really bad move?

    Talking about it? Perhaps... doing it? Usually.

    Why U.S. Dollars?

    Depends on the day & the place. If one is astute & has a pocket full of both, the exchange rate can work in their favor. Currency is fickle stuff, it's value - especially outside the US - can fluctuate wildly, and quickly. One day a few years ago, I happened to be in Kenya when there was a local...

    It's That Time Of Year Again. Idiot Boaters Don't Know What A Dive Flag Is

    In Alabama one must have a "V" (Vessel) endorsement on their driver's license. When they first passed the law, folks my age (I think born before 1950) were grandfathered in & automatically got the endorsement, as we'd been driving boats for years (perhaps the FL law is new & 1988 is the...

    It's That Time Of Year Again. Idiot Boaters Don't Know What A Dive Flag Is

    Hmmm... hopefully one could get the hull number. Then there's a whole bevy of defenses available that could be very convincing - and motivating - to the boater to be more careful and respectful of divers. How 'bout this one, once you've tracked 'em down. "Hey bud, How's about letting me treat...

    Why U.S. Dollars?

    Because they want US dollars. :) Rick

    Is Side Mount the new DIR??? Building resentment towards us as a group...

    Hmmm... hmmm... interesting... I have no idea if my sidemount rig conforms to anyone's standards or not. It predates any of the new dedicated sidemount stuff, so I'm pretty sure it doesn't. And AFAIK there were no sidemount instructors or courses around; maybe I ought to grab me one, take a...

    Air integrated computer and tec diving

    Interesting thread... Just a couple of thoughts. First, from a safety perspective, I have no problem with someone else using AI transmitters. I personally prefer brass & glass. Custom tables in caves... if I'm doing a cave dive that requires deco I'll run as close an approximation as I can in...

    Enhanced air...does it help fatigue?

    My bride the Lovely Young Kat says she is less fatigued when using Nitrox than when using air. I, on the other hand, can't tell a speck of difference. She sez I'm insensitive :) Bottom line... YMMV. Rick

    orientation dives for new Homestead resident

    Just did a week with Quiescence in Key Largo. Strictly six-packs. We had a great time; the boat captains were accomodating & found the dives we were after. Highly recommended. :) Rick

    How many of you make a habit of picking up trash when diving?

    It's an interesting question, and my answer is "it depends..." Some trash is just trash and can be removed without harm, and even with positive impact. But the ocean is a soup filled with critters looking for a home, and much of the "trash" we see, especially if it's been down for a while, is...
