S60 Distances Off

I have an s10, distances always spot on.  I upgraded to the s60 can't say the same.  +/- 10 yards consistently.  Also compared with others in my golf group who have GPS watches, s10 always  accurate, s60 i hit and miss.  Hard to play with the watch when you can't trust the distances.  I have checked the unit, I am using yards!    

Factory reset does not work.

Is there a function within the watch to reset the GPS?
