    Semi-DIY O2 and CO analyzer

    I'm convinced of the benefit of analyzing tanks for O2 percentage and presence of CO (carbon monoxide). I was a kickstarter supporter of Cootwo, and still think it was a great concept and form factor. I was unhappy with the lack (and tone) of support from Divenav in the past. On my last dive...

    Advanced Beginner Gear Grab - Helpful for others too?

    Alrighty then. I've managed to get irritated enough in about 15 dives to want my own gear (more or less) immediately. Like most of us, I have pockets that you can see the bottom of and want to choose wisely. I would consider myself an "advanced beginner" or "beginning advanced" due to...

    Importing Apex Regs

    Hi all, I've just ordered some Apeks regs from a European website and it has since occurred to me that as the EU has regulations surrounding what connection can be used with EANx (anything above 21% O2 uses the M26 connector) that the DIN regs I've ordered may not be nitrox compatible/oxygen...

    Nitrox on Little Cayman

    I have coordinated a small group heading to Little Cayman Beach Resort this Fall. My wife and I have only been Nitrox certified since last summer. Is it worth it to go with nitrox on the boat dives that LCBR would normally do, meaning sites close for their boats? I don't want to shell out...

    Why O2 before Air for PPB Nitrox?

    This is probably a basic question answered in any Gas Blender course, but it came to my mind and I can't find the answer online. Why is the procedure for partial pressure blending of Nitrox to put 100% oxygen in the empty tank first and then top up with air? Wouldn't it be "safer" to add the...
