Today I did a dive from Dive Tech to a little fishermans marina just about a quarter mile towards town. There is some great coral along there and so many fish…. I like making the one way trips on the rebreather, I see a lot better stuff. We just put all the gear in one car and leave the other at the get-out place and drive back and get in and dive to where the second car is.
Today I had an almost incident. I was at 145 feet and wanted to add some diluent and added O2 by mistake. Then I couldn’t figure out why my PO2 went up (to about 1.45). So I tried to add another little squirt of diluent and added O2 again. My PO2 went up some more and I quit breathing and exhaled as I tried to do a dil flush but used O2 again. MY PO2 went WAY WAY up (Like 2.55 PO2) but I wasn’t breathing it. Then I switched to my bailout gas and at the same time realized what I was doing wrong and did a flush using the correct gas and everything came back to normal. So I went back on the loop and continued on the dive. I never breathed any PO2 higher than 1.6 the whole time and the whole thing was over in seconds, but dang! It could have been a really really bad screw up! (You add O2 by pressing a button on your right and add diluent by pressing a button on your left, I was pressing the wrong button).
