Building The Under $50 O2 Cell Checker

macado

I have been interested in building an O2 Cell Checker for a while now, not only to test if my rebreather cells are current limited but also to check the linearity of them. That is when I remembered seeing an older thread on RebreatherWorld.com aptly named “The Under $50 Cell Checker”  A bunch of people on that thread had some really cool designs. I merely copied what other people were doing and can’t take any credit for this idea. So the question is can you build a cell checker for…

My CCR Cave Diving Course with Paul Heinerth

macado

A little background information first.  It was a while ago that I started my “full cave” journey.  In March 2012 I took Cavern/Intro/Apprentice with German Yanez in Cozumel, Mexico.   He was a great instructor and I really enjoyed class with him but this was all on open circuit and to be perfectly honest I haven’t dove doubles frequently enough in the last two years to want to complete my full cave on open circuit.  I still dive OC but I just prefer to be on a rebreather for most dives…

Trip Report: USCGC Duane & Molasses Reef with Rainbow Reef

macado

So I had been having multiple conversations back and forth with the Rainbow Reef staff about whether or not they could rent me rebreather cylinders and a bailout bottle.  I even tried using words like “small tanks” and “pony bottles” to no avail. Unfortunately I couldn’t get anywhere with them.  It was a little disappointing since my other interactions with the staff and experience on the boat was fine so I don’t want to paint them in a bad light but just give a little constructive criticism. The email response…

Caustic kitty litter: Bringing your rebreather to Cozumel redux

macado

I decided to bring my rebreather down to Cozumel again since I was going to be there a month and wanted to get some deeper dives in. You can see my August trip report for more thorough information. As per usual I brought my rebreather on the plane as carry-on. I dive a rEvo II Mini which is about as travel friendly as any 45lb rebreather can be. After removing the tanks and stand I wrapped the entire unit in a grill cover to make unit look like a backpack…

Bringing your rebreather to Cozumel

macado

As someone who just recently switched to a rebreather this year I had not had the opportunity to fly on a plane with mine yet although I’ve taken it on plenty of other trips that involved driving. Nevertheless I decided to bring my rebreather down to Cozumel for this trip to see how much of a pain it would be since I frequently visit Cozumel 4-5 times a year. I wanted to see if it is worth lugging down for most trips. This will be a long post so I…
