    Wing Size/Doubles Weighting Math

    I don’t really understand what you’re saying Assume you start a dive with double hp130s with nitrox and a 100% o2 deco cylinder Min gas for that dive is 1000psi so you are using 70% of the nitrox in those tanks Also assume you have a perfectly balanced rig that is neutral at the end of the dive...

    Oxygen Clean Tank Valves

    A shop that doesn’t get at the very least an annual test shouldn’t be operating imo We had one in my town a number of years ago that was found operating with terrible results They’re out of business now but there is no oversight or regulation for dive shop air quality

    Bad scuba advice you've received

    Anecdotally, I partial pressure fill my own tanks for nitrox. For a 3500psi tank I’m usually adding around 400-450psi of o2 to a cylinder with around 500psi left in it The needle on my whip gauge changes at a different rate than my spg if it’s hooked up and usually ends at a different pressure...
