We have a par 3 that can vary by 40 yards depending on the position of the flag and the tee markers so it's still handy to have a rangefinder.
Our shortest par 3 can vary by 25 yards on the tee and 30 yards on the green. What I am saying I look at the flag position and look at the tee position and 30 + years of experience has taught me which club to use.
