I would conservatively estimate that the Pinseeker saves 2 to 3 strokes a round. It takes the guess work out of those bluer than blue pin placements as well as those reder than red. It can even save more strokes on courses you haven't played before by telling you distances to carry gullys, how far it is to the lake, etc. Cannot golf without it!
Pros: No longer need to know the pin placements of the day.
Cons: Weak battery latch. Requires line of sight.
