Lessons learned part two
So I’ve been trying to figure out how I went from 400 psi to zero so quickly. Did I not check my pressure frequently enough? Was the gauge inaccurate?
Well, I figured it out. I have a gauge that measures pressure in bar, with tape on the face indicating PSI:
Notice the 500 psi mark (leftmost on the tape), which should be about
34 bar, actually lines up with about 12 bar, which is about 175 psi….
The rest of the marks are pretty accurate, but they aren’t the ones that really matter…zero is still zero no matter what units you’re using.
So, I screwed up the scale when I put the tape on there (been using this gauge for about 25 dives). In retrospect this wasn’t the best idea. I should have either gotten a PSI gauge or adjusted to reading the bar scale. I’m planning on buying a PSI gauge ASAP.
