The Grinder Of Pars (Semi Crocked)
I must say I have found a similar problem to Jimaroid with shotscope. We have a long par 3 at 220 yds both on the measured course and according to the watch but when I was hitting the middle of the green it was recording distances of around 170yds. I stopped using it after that as I realised there were other unnoticed but significant errors.
I still like it as a GPS but I am slightly sceptical of the data coming out.
No idea what Arccos is like.
GPS is accurate to about 3 to 5 yards most of the time but can be as much as 8 yards out.
When you consider that the distances recorded by Shotscope and Arccos include roll - which can vary from a negative amount with a wedge to 70 or more yards in firm, windy conditions - I can't get excited about the numbers.
I constantly hear of people having to edit shots....are all bad numbers found.? Are they all corrected accurately?
Carry is the only distance measurement that matters, it's the only one you, sometimes, have any control over.
None of these give you carry.
I've tried all the shot trackers - I don't use any of them now.
