    hp vs lp

    Take a look at this chart: http://www.nwscuba.org/resources/rec-diving/Scuba%20Tanks%20and%20Buoyancy.pdf A HP119 is roughly the same size as a LP95. They are basically the same size and have pretty much the same buoyancy characteristics with the HP119 being slightly more negative when full...

    Single tank Sidemount with HP100... weighting on the opposite side?

    A steel HP100 is somewhere around -3.5 empty to -8.5 full. An AL40 is around -1 full. If its for redundancy and it stays full, then you are probably right at around 5 pounds. That will put you in the middle of the buoyancy swing of the hp100. If you are going to breath off of the 40, you may...

    HELP! I want to dive in VA Beach!

    Try the Ocean Explorer. I think Dive Quarters books with them but not always. So, perhaps they are still running.

    Bad experience on very first dive... looking for some advice

    Steve, It is important to remember that overweighting will make buoyancy more difficult. It does not make good buoyancy impossible. I regularly dive overweighted so I can chase students and give up weight if a student is underweighted and still have enough for myself. With experience and...

    Agency differences for certs

    First, ask yourself why you want the rating. If it's because you want to work as a dive master go with the agency that the place you want to work for uses. Doesnt make any difference whether it is here or abroad. That said, PADI is the largest and you will probably have more options for places...

    Aqua Lung Dimension i3

    It can and does happen especially as the gear ages. Little plastic parts in the mechanism can weaken/crack and then they fall out easier. It happened to my wife during remove and replace weights in her ow checkouts. At first we thought that she just didn't get it back in properly. But, after...

    Virgina Wreck Dives

    I went out on the Ocean Explorer. Nice boat nice crew. I'd go out with them again. I tried to go out on the Miss Lindsay with Lynhaven dive center. They cancelled due to poor sales and didn't bother to call me and tell me. I found out when I called them to confirm. I live 3+ hours from them...

    Bad experience on very first dive... looking for some advice

    You are not a screw up. Buoyancy takes practice. If you are a little overweighted and have air in the cell, when you start ascending that air will expand and make you go faster making it expand more etc. Bouncy is also the most difficult in the shallow water. I suspect you over weighted and it...

    BP/W banned in DM Course

    @Heath DMCs are not slaves. Neither are DMs. Don't put up with that. Should you help out - yes! Its part of the gig. Should you be doing things that make you bitch under your breath - no! That is a sign that you either need to better understand why you are asked to do something (because...

    DM swim tests...what a wake up call

    I agree. Plus, its pretty easy to get a 5 on the float/tread so its OK to come in slower on the other swims. I'm not a great swimmer, but I think I'm a reasonably strong swimmer. I don't swim well, ever. I don't really enjoy swimming. But, I got respectable scores and it did give me some...

    BC off and on underwater.

    It would have to be extraordinary circumstances to get me to take my rig off underwater. In fact, they are so extraordinary that I'd probably be leaving it on the bottom. So, I'd likely grab a weight pocket so I'm not super buoyant and make a break for it. The other scenarios - loose tank...

    fins, fins so many fins.

    Maybe netdoc just had crappy fins. On the surface, I'm much faster in splits than paddle fins. If an instructor rags on your splits for a rescue class tell him to pull his fin out of his rear and find someone else to teach you.

    the nicest mask for my woman.

    Trying it on is best. My wife was looking for something similar and ended up with this one: Oceanic Worldwide - Scuba Diving Masks for women and narrow faces - Ion 3

    LGBTQ Divers?

    I've got a dive buddy whose gay. Dove with him many times. One day another dive buddy said "you know he's gay and the guy that comes along with him sometimes is his boyfriend, right?". To which I replied "no, I had no idea. Why didn't he say something? Oh well, you ready to go?". It's time to...

    Code of Conduct for Diving with & Photographing Pygmy Seahorses

    Five photo limit? What is that so that his photo sales are better? The number of photos taken has nothing to do with potential damage. At most, this would seem to be targeted at limiting the time spent in a location to limit potential damage. If so, say no more than 5 minutes or something...

    Hoseless Air integrated computers

    I never had a problem and I'm not going to buy an extra gauge for a phantom problem until it happens and becomes a real problem. The thing is, the "You're gonna DIE!" crowd forgets that your tank doesn't suddenly become empty if your gauge dies. If the computer is dead, you are aborting the...

    Dive Shop in Ashburn area closed? -> who sells Pinnacle wetsuits

    Splash dive center in Alexandria lists them, but I don't remember seeing much pinnacle stuff in there when I stopped in. If you are set on pinnacle, you may want to go through somewhere online like leisure pro with a fit guarantee. It'll be faster and more convenient than having a shop order...

    New Pony Bottle!

    Nice. Recently, I added an octo holder to my pony setup to keep the reg from getting loose. It works pretty good. Your reg looks like mine did prior to the oct holder.
