A positive addition to my game! Don't worry too much about the steady hand concern, Pinseeker works well and truly saves me strokes caused by distance error. Now I'm the "official" crier of yardage for any group I'm in (maybe the only down side of this tool). I feel this is much better than GPS because you have infinite target options and, if your on the road and don't know what courses you may play, no computer download or preplanned golf is required.
I used the V2 right out of the box, although I read the manual while awaiting arrival. The V2 requires you be a little sensible regarding the distance, and if the reading doesn't seem right, I simply scan again to verify. The slope option is well worth the extra $$ and, for me, it's dead-on. I simply can't see how someone would be disappointed with the V2 rangefinder.
