I have used the S70 for a few rounds at my home course, but the last two rounds the distances have been way off.
On one hole tee to green with my Z82 shows 324 yds but the watch is showing 227 yds. As I get closer to the green the differences are less. When I'm 80 yds out the watch shows 20 yds. When I'm about 170 yds out the watch shows 120 yds.
I haven't received the new update yet but don't know if it will fix the issue.
