    What about residual (?) nitrogen?

    (With apologies for bad terminology) I follow (as a layman) the theories about nitrogen loading (while at depth or descending), and nitrogen "off gassing" as you ascend. My question is : what happens with/to the nitrogen in the body at the surface-for non divers as well as divers. Does it just...

    # Of Posts Vs # Of Pages???

    Until today, (IIRC) when I looked at "new posts", there were 10 pages, with each page containing 20 posts. Today I see 20 pages , each with 10 posts. While both modes get the same total # of posts, IMO the 10 page/20 posts per page is better.... That said, and realizing that I could be imagining...

    New batteries-how to get up to full power.

    I use an Oly tough stylus 8000, and it does what I need it to do. I have ordered new batteries (Li-50b), as one of the old ones is not getting the same charge level it used to get (running out during a dive compared to lasting for a full dive +). I'm planning, of course, to charge the new...

    Change in Scubapro's warranty service rules?

    Last week, I dropped my regs off to get the annual servicing ( under the "parts for life" program), something that I have been doing each year since I bought them. Today, I get a call from the tech, while he is servicing them, saying that Scubapro has a new policy, wherein regulators with less...

    Question re old "new" wetsuit

    Long story short: I was recently given a "new ", never wet, wetsuit, that was originally purchased approximately 10 years ago. It is a 3mm O'neill suit, that was kept in a closet since originally purchased. it looks and feels new, and it fits. My question: is there anything more that I should...

    Weight check at start of a dive??

    I just returned from a trip. The diving was good, but I have a question regarding how this op approached weight checks (6 different DMs, said the same thing, so it probably is the op’s idea). They asked the divers to please do a weight check at the start of the dive. The DM then explained how...

    Aquaseal or??? to secure knee pads

    Hi to all, I have an older ( 8 years+) Henderson Gold Core Suit . It is in good shape except that the knee-pads have begun to peel off. The top 1/2 to 3/4 of an inch has separated from the leg/knee of the suit.The tops of the pads do come up over the knee (no kidding!), and are subject to all...

    Where to put emt shears on a Stiletto ?

    I just purchased a Stiletto, to replace a Concept 2. I'm in the process of transferring the various accessories from the C2 to the Stiletto. So far, so good. The one snag is the "Sea Snips" (EMT shears). They (in their sheath) fit nicely on the shoulder strap of the C2, ( just above the top...

    "Nitrox poisoning"-tv dialogue

    I was watching "NCIS" last night, and the episode involved the investigation into the death of a supposed Navy diver, whose body was found washed up on a beach. The diver's tanks had the green "Nitrox" stickers. While the Nitrox played a less-than- infinitely small part in the plot,the writing...

    ?? re the science behind water feeling colder

    I have frequently heard/read statements like "water takes your body heat ## times faster than air". With different values in place of ##. (This is explaining why you get colder, faster in 70 degree water than in 70 degree air.) Based on experience, I agree. What I can't seem to find is a...

    Alert diver article on Deep Stops

    I don't know if this is old news, but I just got my winter 2010 issue of Alert Diver, and skimmed through the article on deep stops and recreational diving. I'll need to look at the article more carefully, but if I read it correctly, the panelists (?) were dismissive of the concept (for rec...

    any experience w/ the tough stylus 6000/8000

    I saw the Olympus tough stylus 8000 at the Oly booth at "Beneath the Sea", and I liked what I saw. (I'm looking for a smaller setup than my C-5050.) However, when I read online reviews, the comments were " very rugged BUT..picture quality not great; noise, lack of contrast even at ISO 200"...

    Feet during giant stride ?

    Perhaps an odd question. I was asked it last week by a new diver, and I had no real solid answer. The question was "what, if any, is the recommended position for the feet when entering the water using a giant stride?" All I could say was that it helps avoid a faceplant if your leading...

    Gear configuration question

    I was wondering if anybody could clarify the logic behind the following gear configuration that I saw the other day: the guy had a long (5 ft?) hose first stage, with a "standard" octo.The octo was attached to a regular octo holder, on a chest D-ring. I am aware of the rationale behind the long...

    why helium?

    A question from a "rec" diver: What is the purpose of adding helium to breathing gas. I'm assuming that the HE replaces some of the Nitrogen, but what does that accomplish. Does Helium have properties that make it 'safer" DCS wise or ???? Thanks in advance. Sorry if this has been...

    Unexpectedly redirected?

    It is important to point out that I'm a slow/lousy typist, and as such, when possible, I use a program called Dragonspeak in an attempt to make things easier. It is a program where I speak into a microphone, and the program types what I said (with at least some degree of accuracy). I point...

    NAUI ? : stops done "at a stop"?

    Last week,on a trip, during a surface interval, the subject of "deep stops" came up-(among a bunch of recreational divers). I stated that I like to add a "half depth stop", in addition to the regular safety stop, on each dive. I also mentioned that , on the previous dive, (70 ft max depth), it...

    Spring straps: how snug is enough?

    Hi to all, The question is about spring straps. I'm going to use a pair of "Innovative Scuba" spring straps for my SCUBA Pro twinjets. These are the type that have buckles that fit onto the buckles on the fins. (I am aware of the "why introduce another failure point?" discussion, but...

    O-ring "shelf life?"

    Hi, I've been out of the water for almost 2 years, due to a variety of medical things, but will soon be returning to diving. My question: the o-rings for my housing have been "waiting patiently" in their plastic bags. I'm not sure, if I ordered new ones, that they would have spent any...

    up too fast? go back and do it again ???

    While talking to a non-diver, who was interested in the activity, and had many questions. This situation came up. I was not sure what the "best" answer would be, so I thought I'd throw the question out to the SB experts: Suppose a diver realized that he had ascended too fast-(not to the...
