Thanks for the tutorial, I enjoyed it. Give me time and I'll reply, hopefully. BTW, I edited my message, just wordsmithing. Dennis

Dr Thomas, this suggestion may be nothing to get excited about but if you are looking for "out of the box" ideas, I have one to offer. Don't ask me for details just yet, I'll work on some examples if this has merit. You may need to stop thinking of the counterlung(or loop or whatever it's...

Deleted due to computer glitch.

Pasteur had it right. I say that because there is something compelling about the particular dominoes that have been falling. So little we know. Where are the great unification theories in physics and medicine? On the other hand, if we knew everything then where would we be, at God's right...

Scubydo, "balanced" when applied to the first stage indicates that the internal design is such that the supplied intermediate pressure does not vary significantly with changes in tank pressure. Historically, the Conshelf design, which is carried over to the Titan, is an adaptation of the first...

Very well, I reread it. I guess the concept of throwing a diving set into the water without a tether is alien to me. If nothing else, the current will sweep it away.

Why Dr Thomas, you rascal, I do believe you have a card up your sleeve. Would you be per chance, or by design, fashioning a theory concerning certain incidents among Inspiration users? I'm sure that K.N. is all ears.

Ralph, you forget to add her "intrinsic" buoyancy which, from her own description, is about 16 pounds(20 lbs less 4 lbs tank buoyancy). As has been discussed, this number is high and needs to be confirmed in a pool...+3% of course.

I ran across this transcript of a conversation with David Berg, M.S. Paraphrasing; as a result of pathogen(s) activating the immune and coagulation systems the blood viscosity increases, blood flow diminishes creating anoxia and nutrient deprivation.... This also explains why low dose...

>>Your BC isn't there to lift lead weights<<< Graybeard, Zept, I agree. Doc, you're hung up on the mechanics of buoyancy, and it seems to be related to the recent practice of cramming the weights inside the BC, and which leads the newbie(you?)to conclude there must be some kind of parity...

Nice. Seems to have good downward vision which is useful also.

Don't get hung up on the weight capacity of a BC. Those pockets are really only there to provide "trim". There is no design relationship between a BC's buoyancy and its lead capacity. Most of your lead weight should be on a belt. I have no idea why anyone would try to convince a recreational...

I've never seen so much brain power brought to bear on this issue. Pug's first post was the right one. Get the 24 pound Diva. That is more than enough buoyancy for a 5'4" woman, size 18 or whatever and who will be diving rental tanks and a wetsuit. Figure out the weights you need to be slightly...

Seemann sells the Champ/40155 but I couldn't find a picture. Maybe it looks like the "Sharm"/40165? http://www.seemannsub.com/frontend/shared/main/index2_ek.cfm?CFID=1022347&CFTOKEN=40611671&SEITEN_ID=katlist.cfm&PICID=10

Big deal, heh. BTW, don't forget there's an oval window as well.

Hey, WrecnCaver, when I warned about this problem a few months ago a well known med reg said I was spreading misinformation. Of course, the "etiology" of the problem could still be argued. If your inner ear is filled with water get it drained pronto.

You fella's are over my head. Rectified diffusion? Aquamore, I don't understand the EM analogy. An electromagnetic field doesn't "collapse", the wave simply propagates into space. Are you perhaps talking about a collapsing current in an electro-magnetic coil or similar ?

Badger, it might be premature to jump on the technical bandwagon. Trimix diving is more than math. It also involves extra expense, level of care and risk. For what, a dive to 100 feet? Not worth it. Around these parts trimix and O2 are used on a few deep wrecks such as the Ocean Venture(250')but...

If I were going to do like most people and have a regulator serviced every year I would buy a piston type. I believe there is less chance that a tech will damage it in some way. The diaphragm reg should be less susceptible to long term environmental problems, but the differences are...

Right on about the excellent Biofins. Too bad Doc got too large uva' size. I have been warning about the size problem with most modern fins but got lost in the noise. I ordered my Bios in summer of 1999 directly from the USA rep. She took my data and my money and recommended a size medium which...
