You can get them through KISS now. I'm not sure if they have them in stock.

These were my preference with the scitech seals. Simply replace your seals with the glove...

I stayed at the Marriot last year. Goby Divers was more than happy to provide deco bottles and whatever mix I wanted.

Technical divers don't use more conservative settings to deceive or trick themselves into more deco time, they do it because they believe it keeps them safe. Therefore, skipping deco(less conservative setting) is not an option. Expanding on what @tursiops said, a big chunk of technical...

@grassybreakfast For me, my GF settings are already way more conservative than standard for recreational PDCs, so if my PDC says no deco than a safety stop is likely not warranted. Also, technical divers are expected to be way more controlled and typically don't need to target safety stop...

True, but I don't think individuals having day to day variability negates individual variability over all. It just means individuals need to dive like it's going to be one of their bad days.

The scientific evidence is based on the average outcome from all the people/animals that have been tested. It is good to get to know your body and adjust (within acceptable ranges) for your own personal tolerances.

I can see an unlikely scenario where the pull dump valve is stuck, so the corrugated hose got overpressure. In this case a good rinse and soak should take care of it. My best guess, the original zip tie slipped/broke, then the replacement wasn't installed well. You did replace it after the...

There are places worth visiting that require stages even with a backup DPV.

There is nothing sterile about the human mouth. I rinse with water, then with Streramine then let air dry. For multi day trips, I rinse daily and Steramine about once a week.

The scaling factor from air to oxygen is based on relative FO2, so for linearity checks you always use 20.9%. As @inquis says you do have to adjust for relative ambient pressure when comparing historical measurements.

Maybe I missed it in some other comments, but you should be deviding your air measure by FO2 (20.9%) not PPO2 to calc your expected linearity to 100%. Altitude is not relevant.

This makes it vary easy to get into a situation where your buddy does not have enough gas for you in an emergency. Have you and your buddy done gas matching for the dissimilar tank sizes? You will probably find you still need to call the dive in about the same time, you just have more leftover...

Sounds like how I would feel if I was carrying tanks around for a few days, then didn't pay attention to nutrition one day. Maybe a little bit of muscle fatigue, a little bit of arthritis, a little bit of hypoglycemia, and a mild ear infection from water exposure?

My Oxycheck O2/He unit is two devices daisy chained in the same case. Looking at form factors on their webpage, I'm sure I could add their CO analyzer to the chain(Expedition O2 + Expedition He + Expedition CO). They used to sell an O2+He combo, but I don't see it on the site. The case mine...

@lowwall As @Wibble said, the more meticulous you are the more confidence you have in the unit. That, said the KISS units are already simple and easy and the GO looks even easier. I would say 20 minutes on top of your normal setup time. About the same to break it apart rinse it and lay it...

I've had good luck with food grade silicone. Seals it up but still allows disassembly.

I used to read a comical cycling blog, the author says there are three levels of cyclist: Beginners Freds/Wilmas Douches
