    DIY Nitrox Analyzer (Arduino based)

    https://www.adafruit.com/product/3199 Any thoughts on using this as a CO sensor?

    The best place to install an octopus?

    This isn’t my reasoning (I have a long hose and backup on necklace), but I heard one DM say that he has his octo on the left to leave his dominant right arm available to better control a panicked ooa diver while simultaneously donating.

    Which backplate and wing???

    I bought the dgx harness, aluminum backplate and 30lb wing as my first rig and I’m loving it (did my AOW practical dives in it and worked like a charm). Simple, comfortable, effective, affordable. Also, fits like a glove after some tweaks. I put two trim pouches on the bottom tank bands and...

    Minimalist single tank rig

    Really cool seeing this!

    Minimalist single tank rig

    I agree that single tank side mount is more complicated than back mount. My hogarthian back mount is as minimal as I can get. I’m not trying to make it more minimal, just interested in applying similar concepts to side mount for open water fun. I like experimenting and playing with rigging so...

    Minimalist single tank rig

    Ive never dove sidemount, nor do I have any formal training on it, but I’m attracted to the freedom of movement and do have interest in taking a course next summer. I’ve been reviewing attachment methods of popular sidemount harness/bc systems and came across this minimal 22lb bladder...

    Advanced open water dives :)

    I was the only student and had my hover somewhat okay that we decided to throw some task loading in to show me how that changes things.

    Advanced open water dives :)

    Did three of my AOW dives on Nitrox and two more tomorrow. First dives on my new bp/w and I’m stoked! Dialed in my weight and trim, wing bc makes it easy to be horizontal. My instructor had me run and remove a line to three points in a small, open wreck so that was a fun bonus. Things are...

    Recreational Pony Bottles, completely unnecessary? Why or why not?

    For those of you who dive single tank plus pony for redundancy only, do you 1. Still have two second stages on your back air plus additional on pony?

    Dive boat etiquette and buoyancy check

    The goal is to be neutrally buoyant with empty bc, at 15ft, with an almost empty tank. 1cf of air weighs 0.0765 lbs so with al80, difference between full tank and 500psi is about 4.9 lbs. So, I can test neutral buoyancy on surface with a full tank and then add about about 5lbs to what gets me...

    Dive boat etiquette and buoyancy check

    I’m doing my AOW dives this weekend in a fresh water quarry so I should be good to go on technique for achieving buoyancy and trim. I may be over thinking this since I’ll have my f/w weight locked in. So maybe adding for estimated difference in s/w and then end of dive buoyancy test is a good...

    Dive boat etiquette and buoyancy check

    I’ve been diving my new gear in freshwater and plan to do a boat dive in Fort Lauderdale in a couple months. All my previous diving has been in saltwater with rental gear on boats and I would purposely overweight but now I’m more concerned with buoyancy and trim. My question: is it okay to ask...

    Recreational Pony Bottles, completely unnecessary? Why or why not?

    Thanks for clarifying Angelo. I must have glanced past the part in your original post where you mentioned the two independent first stages as a redundancy, which now that I read it again, is a great story of how redundancy can turn a potential massive air loss into an just an annoyance. Do you...

    Recreational Pony Bottles, completely unnecessary? Why or why not?

    I have pretty limited experience but this seems like a poor practice for a dive operation. Knowingly continuing to use defective equipment to rent to divers?
