Worth every cent.
I got this gauge as a replacement for another Yellow Jacket gauge, the 40332 compound gauge with shorty coupler. The 40332 included the coupler, worth about $18, but came new off zero by -3 to -6 psi, and wasn't correctible by adjusting the calibration screw. This gauge, the 49138 is superior in every way but one. It has a greater range, larger dial size (and therefore resolution) and most importantly, is accurate right out of the box as well as being adjustable above and below the zero. It is precise and is a professional piece of HVAC equipment. The only thing it lacks that the 40332 had is the Yellow Jacket brand shorty coupler. So this gauge cost me a net of $15 more. But it is without a doubt the best analog pressure gauge I own. I highly recommend it.
