    Quick Reference: SAC & RMV Chart

    I'm brushing up on my gas planning math in preparation for my next cave diving trip (coming up in two weeks!). To save some space in my Wet Notes/not need to calculate consumption de novo for each dive, I made a chart of RMV for depths of 20-200ft at SAC rates of 0.4, 0.6, 0.8, 1.0, 1.5, and 2.0...

    Shipwreck law research... am I going crazy?

    Dear fellow nerds of both law and scuba, I've been trying to find the most recent text of 43 U.S.C. §§ 2101–2106 (The Abandoned Shipwrecks Act of 1987) for a research project. This does need to be a primary source, so Cornell's LII page won't do at the moment. The problem is... where the hell...

    Shuffle kick? Shovel kick.

    My gas station-grade scraper was not up to the task of last night's snowfall in Chicago. On the other hand, I did have three pairs of fins in the car...

    SS backplates in fun colors?

    I've seen a variety of colorful aluminum backplates, but is anyone aware of a source of steel backplates in fun colors? Ideally, I'd like to find a blue backplate for a new cold-water diver.

    Recs for mask with nose purge?

    Seeking recent-ish recommendations for mask with a nose purge! My preferred model (Tilos Arrow) doesn't seem to be made anymore. Black skirt preferred but not required. This is for a prospective new diver who has limited shoulder mobility due to an injury and can't always handle the range of...

    Logistics for Kőbánya?

    I'm going to be in Vienna for work in July, and it occurred to me that this puts me mere hours away from the Kőbánya Cellars. I now have my heart set on taking a long weekend trip there for my 31st birthday. I'm probably going to go with the Molnar Janos Dive Center, but I'm open to other...

    Reggie Ross - December 24, 2019

    I'm deeply heartbroken to report that Reggie Ross passed away on December 24, 2019.

    Any hope for relaxing spring straps?

    I have a new pair of ScubaPro Jet Fins with about 12 dives on them. Getting the fins on, no problem; getting them off is a production that may involve 1-3 additional divers. The springs are incredibly stiff and it's hard to get good purchase to slide them over the heel of the boot. Is there any...

    Adding helium: some numbers to think about narcosis.

    [Background] This is a very rudimentary look at a single aspect of gas planning: the narcotic potential of the breathing medium. Gas narcosis (whether N2, O2, or CO2) impairs divers' cognitive functions, which poses safety concerns. Understanding/mitigating the risks posed by narcosis is an...

    DIR- GUE Fundamentals: Swim Test Experience Report (August 2019)

    The swim test. The dreaded swim test. Historically speaking, the swim test is a source of anxiety for many divers new to GUE. And it makes sense: most people have swim-for-leisure experience, not swim-for-exercise experience; recreational agencies typically have low-rigor requirements...

    Diving in the Bay Area?

    I have a free Saturday (August 3) while I'm in town for a wedding and would really love to squeeze in a dive while I'm there. Unfortunately, I won't quite have the time to get down to Monterey for the really nice diving. Is there anywhere in the Bay Area itself (preferably southern end, I'll be...

    Opinions: When DOES a new diver become advanced?

    Carrying on from the Introductions forum thread When does a new diver become ‘advanced’!?, there seemed to be initial agreement forming that being an 'advanced' diver is more about mindset/philosophy than raw experience accumulated. With that in mind, in your opinion, what...

    Jammy reel - things to look for to diagnose issue?

    I brought my Dive Rite sidewinder safety reel (one of the newer black models) out to play yesterday, and the damn thing jammed on me continually while spooling out. Reeling back in, I experienced fewer jams but still couldn't get a smooth wind for more than a few feet at a time. While spooling...
