Harry, I haven’t seen these new functions on any of the devices, but I’ll have to look. As for including in competition?????? I would hope and expect that these would be illegal. These should not be used. Just like the slope function on my laser range finder. I only use it when I’m playing a course I’ve never played before and not in competition. Every competition I enter it is usually stated in the rules that “slope function must be turned off”, so hopefully they will now also include and green reading applications.
