    You're probably right, Don... 6) Congo: Let's just call it the Amazon's freaky cousin.

    My "Places I Won't Dive" List (and yours...)

    Well, when you're right your right. It must have been some other kind large of hairy animal. Every large hairy animal that isn’t a buffalo is a wildebeest to me. And you are also right that this is a "dumb" thread. Sometimes it's fun to talk about nonsense. I’m hoping for...

    My "Places I Won't Dive" List (and yours...)

    1) The Amazon: I won't even dip my toe in a place where bull sharks and crocodiles fight it out over wildebeest carcasses. That was perhaps the most disturbing and awesome footage I’ve ever seen. 2) Farallon Islands: The Devil's Teeth read like a bizarro world travel brochure (but a...

    New thread it is! If I show you my list you have to show me yours. :)

    just wondering

    Special Forces Teams use souped up versions of those now. They look like collars and allow them to transmit whispers very clearly. JB

    Great White Vs Mako Shark - help!!

    On the same tangent: I once saw footage of bull sharks and crocodiles fighting over a some wildebeest carcasses. That's when I started my "Places I'll Never Dive" list. I once heard a mako can swim 60 mph and "jump" 20ft out of the water. Not sure of the veracity but it sounds mighty...

    Specific Model Mixing Question

    Thanks everyone. This has been enlightening. It's interesting the lies that are propagated in diving. Thanks, JB

    Specific Model Mixing Question

    It sounds like you guys are pretty technically knowledgeable. I'm not going to ask for any super secrets of the trade or anything but while I've got a captive (unless of course you click "back") audience: Are there any additional concerns, beyond those discussed above, when pairing a piston...

    Specific Model Mixing Question

    Yeah, that was my concern. I don't want to buy yet another high end reg. I'm starting to gag with every new great regulator release. I'm really jazzed about trying out one of the Conshelfs. Some of the more grizzled divers I know go on and on about them. Here's my issue with the tuning: I...

    Specific Model Mixing Question

    For all you gear experts: Can I expect any significant reduction in the performance of a Conshelf 21 2nd stage when attached to the 230 bar Titan 1st stage? I was under the impression that these would mesh well, but one of my LDSs explained that the intermediate pressures would be off too...

    Ocean Men: Extreme Dive

    Dude, did you think it was awfully short too? Anyway, the real freedivers I know are cut from stone. Not a scrap of fat on them and they drop like a lead weight even with a their lungs full. I don't have that problem...

    What is a Good Diver?

    Oh yeah... Their lack of diving skills are occasionally off set by skills in either drink buying or BBQing.

    What is a Good Diver?

    I really can't disagree with any of the prior posts, per se. My only comment is that in some cases you guys have described great or advanced or perfect divers; idols, role-models, and the elite. And thank God for them too. But I believe a good diver is a diver that has mastered enough of...

    Innovative Contraptions?

    Depends which aunt... er, nevermind. :) For the record I'm erring on the side of optimism about getting this project off the ground. JB

    Innovative Contraptions?

    That's pretty cool about the Duke. And let me know if you encounter any challenges with the windows you use. I'm in the process of building an observation dome to be hidden in the depths of my favorite body of water. The real challenge I've encountered is designing a purge for the top of...

    The Dive Buddy's Creed

    This thread is amusing. I'm picturing a dive trip where the biggest knucklehead in the boat is getting into the water covered with athletic-tape names-tags "pre-calling" all his gear. Thank God we aren't that mean. :) Be understanding; be patient; be instructive; and when the time...

    Artificial gills are a bad idea?

    I agree. It would have to be dissolved air that the gills collect. Certainly these units are not breaking the H2O bond. Breaking that bond without the use of another large energy source is still the biggest challenge with which hydrogen car developers are struggling. It’s like the modern...
