I try to refrain from reviewing stuff right after I get it. Tested these two gauges a little. They are in total agreement, with in 5-10 degrees. Also tested in comparison to my digital Thermoworks ambient probe and again within a few degrees of each other, so not bad. I will gladly report back later if given the opportunity after a more thorough multi session torture test.
My elliptical end cap is 10 inches from the weld. So I have to shrink everything down a little bit to make it work. There is no info on the smaller barrel tank included in the plans. Other than that these plans are awesome.
