    When your equipment is in storage

    If my gear were ever stored for that long, it would be thoroughly cleaned and dried. I have several rubbermaid-type tubs which I "store" my gear in; my gear resides in a large walk in closet. My wetsuit gets hung on a hanger, my drysuit is rolled and place in its bag. Tanks are stored upright...

    Staying warm

    Used to dive wet in MN, however about 5 years ago I decided to try dry and haven't looked back. I get cold in the Caribbean in a 5mm jump so diving dry is mandatory for me in water cooler than that. After a bout of hypothermia diving wet at a local hot spot a couple of summers ago, I try not...

    taking a poll, gathering information

    Generally, when there's ice on the lake, diving slows down. I tried Ice Diving last winter, it was a bit of a trip; will go again this winter. The water temp was 39 and the air around 25. However, L. Superior in the summer can be 34 on some of the wrecks while the air temp is 80-90. So, is...

    tank bands

    Curious: is it necessary to place a rubber spacer between tank bands and the tank? What is the rationale of doing so? I have read someplace that this is a standard of practice. Thanks in advance.

    Ocean Reef versus others

    I, too, like the AGA when compared to the larger OR. However, due to visual limitations (i.e. glasses and cannot wear contacts) and the many other features that the OR offers, I went with the Ocean Reef. The AGA breaths better and performs better in all environments that I have dove with it...

    Ocean Reef versus others

    I am looking for opinions on the Ocean Reef Full Face mask (pros and cons) and how it rates against others. We all know Mario's opinion on the Interspiro; are there other opinions out there? Tanks :)

    Sunnto lockouts?

    I have only seen the Vyper (Cobra w/o air) lock out one time: a buddy of mine was diving a 140 steel with a single strap BCD; the strap failed, dumping the 140 at 100 feet (30m); loss of weight = uncontrolled ascent, blown stop (as stated in earlier posts, going up too fast makes for a ceiling...

    Interspiro AGA Full Face Mask

    The AGA is definity a great mask. I like the benefits of a ffm providing a warmer face and the reassurance that my reg and mask are secure. It gets high industry kudos. I would agree with the above post in that the Dive Training magazine article on full face masks was pretty basic and some of...

    Nitrogen Narcosis

    I know that this one has probably been beaten into the rug, however I wish to have a deeper knowledge of nitrogen narcosis. I understand the rudimentary concept that is taught in classes; what I am in search of is a in-depth discussion of physiology; what are the common and uncommon signs and...

    Preflight Procedures

    I will agree with RM on this one: depends on the type of diving that I'm going to do, however, my normal rig usually doesn't have enough time to dry out between dives. See if your LDS has a pool that you can get some time in to test out your equipment. Depending on how much time has elapsed...

    Dive Planning and Computers Vs. Tables

    I have to agree with Mario on this. It's important to understand the physiology behind the instrument that you use. A computer will give you "credit" for ascending to progressively shallower depths, thus effectively increasing your bottom time without hitting a NDL. And, many have the...

    Cobra or Aeris 500AI ???

    I am not a true fan of air integrated computers, though I haven't absolutely made up my mind; I don't know if I like that kind of dependancy. However, anytime you have more than one button on a computer, the learning curve is going to be increased. I like the menu system on both the Cobra and...

    Advice please on hoseless

    Computers, computers, computers ... You have developed a sound list of features that you are looking for: you want a computer that is hoseless, has user replaceable batteries, user settable settings, nitrox. All of these things point to a Pelagic Pressure Systems line of computers. You need...

    Anyone with buoyancy control tips?

    Last, but I am certain not least.... The placement of weight is critical as well. One diver that I know found the right amount of weight, but couldn't understand why she kept floating on one side. She moved some of the weight around in both the weight pouches and on the BCD. Weight in...

    Physical

    From my knowledge, training agencies require a medical form to be filled out, stating that the student doesn't have any of the conditions listed. An example would be the PADI medical, which has the student fill out Yes or No to each item on the list. If the student answers Yes to a question...

    You know you're a real diver when....

    You know you are a real diver when... Your wetsuit is so repugnant that one can smell it 30 feet away and people are moving to safer ground. or While you are diving, the fish are trailing closely due to your wetsuit disentigrating. Cheers :)

    OW student problems............

    On the topic of tables and computers: yes, I still lug around the tables (RDP and navy) and a couple of computers. On the topic of OW cert: the above post seems right on track. I don't believe that the student should be certified as a all out OW, however I think PADI has the option in place...

    What is Pneumothorax

    1. A pneumothorax is a collapsed lung. 2. To answer this question you need some rudimentary anatomy. The lungs sit within the chest cavity. Surrounding the lungs is a lining called the plueral lining. This lining allows slippage during normal respiration so that the lungs don't stick to the...

    internet help needed

    The only site that I know of is Terraserver. There may be others; this one used to be free, but it looks like they have done away with that and now charge a nominal fee. Pretty cool to see things from above.
