    last stop at 3 or 6m?

    TSandM suggested an excellent book that covers your question. It is called Deco For Divers by Mark Powell. In short, it depends upon what algorithm you, or your computer, prescribe to. Some want you to stop closer to the 6m and some towards the 3m.

    Ditchable Weight

    Diving an HP100 with SS PB and 3mm wetsuit in salt water, I'm maybe heavy by a pound at the end of the dive. I could switch to an AL plate so I could wear a couple of pounds to ditch, but why. I should be able to swim up a couple of pounds. In event of a failed BC I do carry a lift bag or...

    Quick question on Rescue

    You'll learn one move, we'll actually a few, for panicked divers. Also there are panicked divers and there are PANICKED DIVERS. With a panicked diver that isn't trying to get on top of you to keep your head out of the water, you can approach them from the front, when they come at you, you can...

    Dive Master or Instructor

    In the end they will have more employment opportunities as an instructor vs. DM. Most working DM's I've seen were instructors functioning as DM's. DM is a prerequisite for any instructor rating. But for PADI DM, they need to be at least 18 years old. So get them through Rescue, CPR/First...

    Spare Air

    I think the Spare Air has a use. If you are diving in shallower waters, >60ft, they are okay. A buddy of mine has a 3ft3 SA. We each took a turn and switched to it a 60fsw and made a slow, 30fpm, ascent. Both of us ran it dry within a breath or two of our heads popping out of the water. No...

    DS Boot Fit

    I just got a DS and it has neoprene socks and requires boots. My street shoes are size 12. The socks of the DS are size 11. When I put on a nice thick pair of wool socks, the neoprene socks fit perfectly. They is no bunching and they don't compress the wool socks. I ordered boots...

    Specialty Courses

    What do your buddies dive? If everyone you dive with is diving Nitrox...take Nitrox. If Nitrox isn't something they use on every dive...take navigation. Navigation is an uber useful skill, you will never go wrong taking that with a good instructor and it will be useful just about anywhere...

    feeding fish and marine life

    Well sure! It is no dummy. Urchins are all spiny and gritty, but the wiener is all soft, yummy, left over parts goodness! If it only knew how good they were at the Ball Park, it would figure out how to breath air.:D

    feeding fish and marine life

    I think these animals do have a capacity to learn and remember. I'm a volunteer diver at the local aquarium. We hand feed a lot of the animals. The divers used to feed a zebra shark named Zoe. I don't know how long ago, the divers stopped feeding Zoe by hand and the aquarists took over...

    The Sandbar Grand Cayman is a Fraud/Scam

    You are not going to believe this. I received a voice mail last night for a gentleman from North Carolina who claims that that he was scammed by Jon last November. If I understood the voice mail correctly he and two other of his friends were hired by Jon. Went through a similar process. He...

    Wetsuit

    Cold water diving can be a lot of fun and if that is what you have locally, I'd look at renting a dry suit and taking the class. You are sort of asking if you can try a Honda Civic for 4-wheel driving in the Baja Peninsula to see if you'll like it. I don't care how good the diving is, if...

    Clear or black...what do you think?

    I found I like black skirts on the masks. I've found the sometimes there was a funny glare coming in from the clear skits on the masks.

    Diver Recertification

    I just looked at the SDI Instructor Manual. Part I, Section 8.11 covers a Two Year Renewal / Refresher Policy. It applies to IT and Instructors. It basically states that they must teach a course at their highest level every two years. If they don't, they go inactive and must attend an update...

    Question for the Masses

    I've always been able to do the math, spelling, and phone number bits (or I just haven't been down deep enough yet). For me the feeling of getting a wee bit narced is the sense of paranoia.
