What's everybody's opinion on digital gauge sets, like the real expensive ones that have pipe clamp thermometers and automatically calculate SH and SC for you.

The idea sounds cool, but I kind of feel blind using them. I like to see my gauge needle swing, and look at how it moves, not just have a digi read out. I also like to look at my individual line temps and compare to ambient conditions and such, not just compare SH and SC values to a charging chart. I also like to easily see my SST and SCT, not just pressures.

I kind of feel like fancy gauge sets like this could lead to an lazy and inaccurate diagnosis

Or maybe I'm just resisting new technology.

Thoughts?
