What does this mean? Did Yoda say this?My tolerance toward fools is greater than my tolerance for SPGs. Zero tolerance for back gas; last stage: 50 bar or less since I've already calculated my Respiratory Minute Volume.

One of several reasons I don't like digital gauges for most applications....not just SCUBA. The engineer in me gets too caught up in the digits....can't stand when things are "off" or when they don't work correctly.Swapped my daughter’s transmitter to my reg and checked pressure. Her transmitter is one I bought in 2013 or so, and read by the VT4.1. My transmitter was refurbished last year. Batteries in both should be equal. Just did annual battery swap last week, so zero dives on either.
11 psi difference. 2045 on hers, 2056 on mine.

that said, 11/2050 = approx 0.5% error
what are the spec'd tolerances of the transmitters? probably more than that
Follow up:How did the tank feel? If it was warm or hot, then that 3000 psi will drop as the tank cools, and it can be a significant jump.
That will work as well. At least you'll then know that there is a difference or not. If your gauge matches, then the problem is either at the shop that filled, or due to the temperature at the time of checking. The owner of the shop I use instructs his employees to overfill a bit to allow for the pressure drop as the tank cools. Generally, I drop off and pick up later, so they are at room temp. Only on one or two occasions has he had to top off.
yep..... especially when compared with a digital gauge that might be off by 50-100 psig.So you’d rather have a big @$$ Needle that could be off by 50-100 psi? Doesn’t make sense.
I'm in this boat. There are things I want better precision on. Like I want to know my depth down to +/- a couple feet. The amount of air in my tank, I like being able to quick-glance like a speedometer. That said i want to know that it is indeed giving me a correct reading during that quick glance.yep..... especially when compared with a digital gauge that might be off by 50-100 psig.
I don't really care if my tank is 2,003 psig or if it's 2,033 psig
knowing that it is really 2,012.5 psig is really way more info that I need to be cluttering my brain with
Add to that the advantages of being able to see at a glance that the relative angle of the needle is where I expect it to be without even registering what the number is
+ being able to see if it's trending up or down without doing math
yeah, I'd rather have analog
For doing partial pressure blending.... yeah I might rather a digital gauge....
Another example..... I have a digital tire pressure sensor system for my camper. Indicates to the tenth of a psig. Drives me nuts when I can't get all six tires to match. It's a psychological thing I guess.
