Easy to use. I usually use pin mode for distance to the pin. Since the laser can lock onto objects other than the flag, I use course distance makings as a sanity check. For instance, if I am about 150 yards out and get a reading of 180 yards, I switch to scan mode. I use normal mode for distances to obstacles. Very much like the waterproof feature. Have not used in heavy rain, but did use in a quick shower.
Better than my previous GPS since gives distances to the flag and not just center, front, and back of greens. Also better for determining club selection to clear bunkers and waste areas.
