The problem with any chronograph that has screens - for me - is that the wind seems to be an issue. The wind is a definite issue with my Caldweld Chronograph's screens at any rate. So maybe the ProChrono is great, but I'm not sure it is the right one for me. I can't wait for the wind to die down in this part of the world.
Wind and lighting.
Bigwhoop, there's more than one way to skin a cat...
