    A BLOWOUT?

    Can anyone give me an update on Peacock?

    DIY Sidemount setup, anyone built one with DECO harness and bladder? Other DIY tips?

    I still use essentially my original DECO harness with my X-Deep wing. The hardware is inexpensive and durable. You will want to invest in some metal buffing bits for your Dremel as the edges aren't too clean from the factory. They will cut your webbing if you don't clean them up.

    Inline valves

    I'm not sure how you would wrap the bungee. On the reg? Valves handles inside? You could rig it edd style or ring style.

    Breathing gas sometimes coming out of my nose in CCR diving. Mask issue or OPV ?

    The opv in my unit is almost too stiff for me to fire doing a positive check. If the opv is firing the loop is unbreathable. It was 50 to 75 hours on the loop before I stopped having the "nose leakage" issue.

    Oxygen Clean Tank Valves

    Not sure. I cleaned the valve, but I think maybe the seat was some incomparable material. It was literally some old valve I had on the shelf for years before slapping it on an AL19 I was planning to use for surface O2.

    Oxygen Clean Tank Valves

    I have had a valve seat toast while boosting O2. Ended up with a valve that woulda close and some rank smelling O2 leaking out.

    Apeks DS4 alternatives for rebreathers

    I've been using some third party Apeks kits for over a decade and have had no issues. First thing to go is always the turret o-ring (just small bubbles). Most of my DS4s are currently 5+ years without service.

    Just what I've heard on SB. So far no issues this week. One person did think my cursive initials where illegible scribble. 😂

    Two dives a Ginnie so far. One blown p-valve and one blown wing dump. Only gets better from here.

    Found at Devils' Eye/Ear

    They probably took it off because it was wet. I can't stand wet socks.

    Is it possible to get into Ginnie off hours with a day pass?

    Hi All, I know it's not great cave timing, but the opportunity to work remote in FL for a month has come up suddenly. Specifically I'm booked at @Capt Jim Wyatt 's Rum House next week, then will be down in Sarasota for three additional weeks. What is going to be my best bet for early morning...

    Counterdiffusion (high-nitrogen-content gas after high-helium-content gas)

    My understanding is it used to be an issue when divers would switch from TRIMIX to deep air(think 200' stop) for deco. If you stick to standard gasses at standard depths it shouldn't be an issue. This means using a 21/35 on the way up, not switching from 10/70 to 36 at 100' after spending 30...

    Dry Suit exhaust open or closed with Razor?

    I don't have it with me for a pic, but you can buy BC dump valves from Oxycheck?/OMS?. You just have to cut a hole and Aquaseal the gasket in place. Cut carefully. I put one in my counterlung a few weeks ago.

    Dry Suit exhaust open or closed with Razor?

    Switch the Razor dump to the right side. I put a butt dump in my Razor and haven't used the side dump since.

    Cave fill final gas volume

    Despite having written a GERG calculator I agree with @Capt Jim Wyatt and @oya, conservative generalizations are easier and close enough until your doing really big dives. For example, if you need double 120s of 10/70 for bailout, a two person team has 80cft less gas than ideal calculations...

    Cave fill final gas volume

    I wrote my own app for blending, mods(end,density,02), capacity, check lists, cell checks, and analysis of historical call measurements. One of these days I'll get it fully debugged and publish it, but at the moment I'm too deep in projects I actually get paid for.
