    Fathom Gemini WOB on partially used scrubber

    How many dust filters are you using, if any?

    Lessons My sidemount cylinder valve spun itself completely shut during a dive

    Color me dubious, especially after reading your other post. Have full roll offs happened in experienced SM cave divers in a cave? Sure. In open water or large pseudo overheads? Unlikely.

    Would you trust capped Petrel3 fisher OC?

    Wasn’t aware anyone was still buying new Fischer computers given availability of better options. I would avoid it if possible. In a pinch, make sure you floor the compartment with some mineral oil and maybe even tape the cap down.

    Half-packing sorb -- Possible, or deadly?

    The Meg and the Fathom (and the SG and iirc the whole HH series) all support or supported different scrubber sizes in the same can with different spacers. Use the wrong spacer, you die. The end.

    Cold hands

    https://scubaboard.com/community/threads/bottoms-of-feet-cold-drysuit-39f-3-9c-water.605892/post-9312794 Would encourage a read of this. Minor changes I’ve made: one size up of gloves with two sets of wool liners, a Brynje mesh baselayer, even looser wrist seals, silly amounts of high fat food...

    What is this used for?

    Self contained underwater drinking apparatus. Best used for consumption of a dark and stormy under some atmospheres of pressure. I am only partially kidding. Some years later, Apollo also introduced another such frivolous device: Bio-Filter Scuba Air Moisturizer — Apollo USA Scuba

    Best CCR in 2025-2030 Rebreather Markets

    You really ought to go get certified and figure out what people in your area are diving. Mares is just as likely to pull a Hollis as they are to continue this unit indefinitely, particularly after the failure of growth of their Horizon rebreather attempt. This entire thread is a colossal...

    DIR- Generic Hosting traveling instructors: how to get the most out of limited time?

    Class payment well in advance with a transparently defined set of terms and cancellation policy. Everyone is “interested” in a class until it is time to lock in the dates and dollars. AAssuming this goes well, would also encourage maintaining a wait list in case someone does bail. Visa needed...

    Best CCR in 2025-2030 Rebreather Markets

    Why? And how many units do you need? Posting for the sake of following the discussion. What you want doesn’t exist or has other notable flaws. You’ll find the units used by most militaries and contractors come from much smaller companies. If you yourself are large enough, you could probably...

    Crotch Strap Sleeve

    Neoprene should stretch over that ring easily.

    Bonne Terre Temporarily(?) Closed

    To ignore the poor treatment of their dive slaves and the silly rules they make.

    Causes of needing to bail out analysis

    I don’t know how often this needs to be said in order for people to realize it. A BOV into a 3L is insufficient if you were to ever find yourself in a CO2 hit. I’d give it a…25%? chance someone with a severe hit with a full face mask plugged into a 3L (even if a full one, which it won’t be)...

    Causes of needing to bail out analysis

    Answer is really just not using an FFM for this style of dives. If you insist on it and continue to use a BOV, might want to switch to something with beefier helium.

    Chest Mounted Rebreather, Hose Routing, and Regulator Fitting Sides...

    Eh. Super fine enough with a Shrimp and an S600. Have gone back and forth using both and using only the BOV and vary it depending on what I’m doing.
