Maybe because they are used to using it? They work like a probe and probably are more accurate than the cheaper probes, but the sequence is not automatic I like this one because of its accuracy and the cycle is automatic and it is a top of the line probe, I really like that!
My usage is mainly hobby related but I do have some parts that are critical and need to be correctly indicated when flipped 180 degrees, I have a few of those coming up shortly, so I will get to use it on those.........
