Agreed. More experience is required. But it's not that expensive for what it can do. The "error margin" can be fixed in the equation on either the display or the logging up front. Or it can be adjusted afterwords in review. So take that with a grain of salt because all of these other sensors are to each their own too.

 

+/- 2 PSI isn't a huge deal as long as the offset is constant. The bigger question is how much the temperature reading changes with temperature.
