I use a SkyCaddie G4, and really like it, though a friend I play with often uses a Bushnell laser that helps us zero in on the pin. I guess that's my only issue with the SkyCaddie's front/middle/back yardages. Seems like a lot of courses I play have HUGE greens, and the laser helps a lot.
Beej, are you telling me that there WAS a reason to pay attention in Trig in high school? And hats off to rjkickers for making Ambassador so quickly -- but shouldn't you be studying. Like maybe trig?
