    Test Data on Back-Inflate vs Jacket-Style

    Thank you for all the response. The reason I asked is my LDS has been pushing me to go backplate for some time now saying it has less drag and can reduce air consumption. ERIC SEDLETZKY reflects my thoughts as I am mainly an underwater tourist. I like to have my flashlight, knife, Lifeline and...

    Galileo Luna Transmitter Pairing Problem "HELP"

    Would like to share this just in case someone still encounters problem pairing or signal loss with the Galileo Luna. Got two sets recently and used it for the first time a couple of weeks ago. One set paired instantly but the other pair refused. The pairing has been done as instructed in the...

    Galileo Sol, Luna Microbubble settings

    My Oceanic DC got flooded and died during my last trip in February. Now got a new Galileo Luna as a replacement and has been trying to learn and set-up this new DC. Have also struggled to understand the MB Level parameter. From reading articles on the Internet, it seems that MB L0 (Micro Bubble...

    It is used for cleaning, not as a defogger. Yes, been using it for several years now and my mask still looks new and sparkingly clean. A few drops is enough to clean the facial off very effectively. It rinses off very well, no worry. After all, its used for eating utensils.

    When to ditch weight?

    The day that it happened, it was even worst. We did went through our BWRAF but I actually just kind of called through it without actually doing the actions. The LP inflator was not connected to the BC. Then, I jumped in with no regulator in my mouth. All this with the tank closed. That is how...

    When to ditch weight?

    Thank you, Nemrod. This is what I suspect. Many divers in our group do not even use weights at all as it is mostly warm water diving with little or no exposure protection. The weight of the backplate or the tank was enough. There are also a couple of incidents of divers losing their weight while...

    When to ditch weight?

    During our OW, we were taught how to ditch weight. After learning how to dive and completing so many dives, the more I am lost about when or what situation warrants ditching one's weight. For example, I will be scared about ditching my weight while underwater. So, can anyone explain what...

    Foot Pain Climbing Up The Ladder

    Thanks for the response. I felt my full fins propel better and is easier to maneuver. But my full fins and open-heels are very different in design and size. So, it is not really a full fins vs. open-heel thing, not really apple to apple. - Don

    Foot Pain Climbing Up The Ladder

    Hi, Switched to full-foot fins some time ago and really prefer it over the open-heel fins. The only problem is when climbing up ladders that have round instead of flat-top steps. It is very painful to the sole. I wear only fin socks when using the full-foot fins. Are there fin socks with hard...

    Things they don't teach in SCUBA school

    About mask fogging, learned something new recently on the dive trip to Raja Ampat. We dive from rigid inflatables and the motor fumes can be too much. I tried to breath through my nose by opening my mask a little so I can smell and detect if it is fumes I am breathing. This causes the mask to...

    Will shooting off a DSMB help protect you from oncoming boats or is this wrong?

    I also don't believe a DSMB is useful in protecting against oncoming boats. I have experienced DSMB deployed by different professional DMs in nearly half of my dives, that will be over 60 at least. Nearly two-thirds of these deployments end with the signal tube lying horizontal on the surface...

    I guess you can call it dish washer liquid soap. ---------- Post added October 17th, 2015 at 07:05 PM ---------- After finding the best strap adjustment, I put on cable ties that basically disables the adjuster. This keeps the strap in exactly the same position permanently. ---------- Post...

    After diving for three years now, there are some things we (I and my buddy) learned from experience (or trial and error). Here are some of them that might help others: Neutral Buoyancy: - I have little buoyancy problem from start but my buddy struggled early on. After trying to deduce the...

    Maximum Bottle Size Rating of Bella BCD

    I stand corrected about the scuba tanks. Checked and was told that practically all the tanks are aluminum. Was told that steel tanks are no longer used due to difficulty in maintenance. So, all the tanks rented out in Asia-Pacific are mostly aluminum. Was told that tanks with flat bottoms are...

    Maximum Bottle Size Rating of Bella BCD

    Just in case someone is wondering how this worked out. We took the new gears diving in Hengchun Peninsula a couple of weeks ago. We're weighted on the dot at eye-level with empty tanks. With tank full, the Bella is capable to lifting the head out of the water to near shoulder height with a 12L...

    Maximum Bottle Size Rating of Bella BCD

    The 10L tank is -7.8Kg while the 12L tank is -4Kg. This is why I am confused by the rating. The Bella is designed with the inner vest restrained to the torso through the cummerbund and the shoulder straps. The air bladder is independent and is attached over the vest by loops. So, the bladder...
