    Question regarding tank fills

    There is a lot to be said for a Faber steel LP 95. Low fill pressure ( 2400 + 10%). At 2640 psi the tank holds a little over 100cf. I like the negative weight too. The down side is that the tank is a little wider and increases drag slightly. The other cats meow is a set of old Scubapro steel...

    Haven't settled on the right BC

    In principle they work the same, I.e. they support the cylinder(s). They also impact my “my package” weight. For example, when diving steel doubles(-12) and a steel plate(-8) when I add the weight of my canister light etc I’m at about 20lbs package weight. That works for me wearing a dry suit(...

    NITROX CERTIFICATION PROTOCOLS - REAL WORLD

    It's your life. If just go with the crowd you cant depend on the crowd to go to your funeral. You probably have been taught to check all of your equipment pre and post dive. The main piece of equipment you need to always check is your thinking. The one time I didn't not analyze my nitrox( and I...

    Leaky octopus

    Ruling out the obvious( nut(s) not tight, hose leak, venturi, if equipped not set correctly for you) it would help to know the model number) of the reg and where you think or see the leak occurring. I'd suggest having the IP/cracking working pressure checked. As noted in another post, it's an...

    Haven't settled on the right BC

    Congrats on the the surgery. One of my family has had it and it has made a huge difference in there life in many positive ways. For what it's worth, I'd suggest you consider postponing any purchase until you are post op. A reduction in your over all body size/volume will impact your trim and...

    My wife is looking for a back inflate BC for traveling

    I'd suggest you look into a travel wing and composite backplate. I have one made by Halcyon that works well for me. It's called the Traveler. I know budget might an issue and there are certainly other travel BCD's out there. I've had great experiences with Halcyon over two decades. I'd also...

    Drysuit diving training

    The primary skill to develop with a dry suit is buoyancy control. The "suit" is one big BCD. "Squeeze" can be managed either by adding air or elevating the "squeeze area" to allow for air to shift within the suit. Be mindful that as the air shifts within the suit it impacts both trim and...

    How do you hover?

    Ditto to the other great suggestions already posted. What I have also found to be useful is my mind set. There are variables in underwater environments. Oceans present surge(s), currents, temperature variations( these impact gas density), and certainly tidal changes. Wrecks and caves have...

    Long snorkel breathing

    It doesn't work because its not a well thought out idea( that is more PC than saying dumb idea..hey I'm trying to make personal progress here.) As noted in other posts, the physics involving atmospheric pressure suggest an exponential doubling and increase in the internal working pressure...

    Regulator Necklace on Primary

    I dive with a reg on a bungee necklace positioned just a little below my chin. I can lower my head and pick it up with my lips. My experience in sharing in an out of air situation is that an out of air diver will swim up and rip the reg out of your mouth. That being said, my primary reg for...

    100' vs 130'??

    A couple of thoughts came up for me when reading your post. I would invite you to ask yourself some more fundamental questions: 1) is my ego driving my desire to dive deeper as if I am going to earn some merit badge and/or respect or bragging rights in the diving community? 2) Am I totally...

    Brand Advice for BCD/Regulators/Tanks?

    Welcome to the learning cure of scuba diving. The ear issue is important. There has been some great advice already shared. If you can close your nares together gently and exhale GENTLY against the resistance you should feel or sense your ears "pop" and clear. As you progress in your diving...

    Changes that Senior divers make?

    In 1998 I dove in Truk lagoon with Chuck Nicklen( under water cinematographer of some note) of San Diego. Chuck owned the Diving Locker in Pacific Beach, CA. Chuck, as I recalled was in his early 70's then. He was pushing his under water camera around the top of some of the wrecks following the...

    At what point should I get diver insurance?

    I've been a DAN member since 1991. It paid for my chamber ride in 2000. I've more than recouped my expense. I feel like I'm supporting a worth while cause, research and service. It's a privilege to have it. Is also is great coverage for a lot of things especially if you are more than 50 miles...
