This may be okay but I have serious doubts,my mate uses a phone app and is always at least 3 yards diff to the Skycaddie...I know which one I trust having seen the extensive workings the company take in mapping the courses.
You honestly think 3 yards is going to make any difference at all? The only people who hit to that level of accuracy have walking, talking yardage indicators...
Yes
Ok, hit a seven iron, then hit another one 3 yards further. Then repeat that ten times with a, hmm I'll be generous, 50% success rate and get back to me.
....where do you draw the line then?
You don't, because you have no idea which of the two devices that are showing different yardages is actually correct.
GPS isn't even that accurate, I believe the stated accuracy, now that the US military have opened things up a little, is still around 2 metres, it used to be more like 20.
