The rangefinder vibrates when it detects the flag. The number of meters fit and if I would meet with greater precision, all would be well. So the length fits already, I'm just usually left or right, and that's a huge improvement. I used to have a clock on your wrist, but you sweat less, and now that she's gone, I'm relieved. Especially good it is to measure the meters to the flag under 60 m. It looks a little ridiculous, but if the ball is on the floor, then the other is no longer laughing. Thus, it saves time. So strong buy recommendation!
