When a rangefinder says it is 150 to the FLAG how far is it to the hole assuming the flag is 6 feet above the hole?


How tall are you?

That's only if you put the laser on the ground where your ball is. And it's assuming you're using a white ball, and not a day-glo orange or yellow.

Duh, Bill.

It's not like I don't know that, but nobody asked for details. I only show my work when I have to.

Forget the science. Just hit a ball 150 dead and see how much you're left with. It would probably measure about 220 for me....

it's a trick question

150 yards to the flag - which, on average is to the EDGE of the flag stick - so center of hole is 150 yards plus 3/8 of an inch.

now a hole is 4.25 inches across - so the edge of the hole is then 2.125 inches closer than that

now, if you stand with your toes aligned to your balls - you heard me - it's likely that you have to remove 3 cm since the sensor of the rangefinder is back about that much and you are overestimating then......

so 150 yards + 3/8 inch - 2.125 inches - 3 cm

so = 149.946 yards

I'd use my 150 yard club if you have one - don't want to leave it short.

Turns out I was wrong - I went to the 150 yard marker and put my rangefinder next to my golf ball on the ground and scanned to the hole - apparently the marker is wrong as my rangefinder said I was only 2 inches away.  Clearly a putt from there.

When a rangefinder says it is 150 to the FLAG how far is it to the hole assuming the flag is 6 feet above the hole?


What's the slope percentage (negative or positive) between your ball and the green?

Is the range finder a slope or non-slope version?

Is this a serious question?

I guess so, but with OP's nick being what it is I bet we get the question again today.

I dont know about all this Range finder math...

I know i look down at my Garmin G6 and say hmm 150 to the flag.. Pickup my 7 iron and pray i get it somewhere on the green..from glance to ball strike is about 20 seconds

I have a buddy that uses his range finder on every shot..  he takes forever.. i glance at my G6 and say.. Mike its 140 to the pin... he says yep mine says 141... then 5 minutes later after he puts his range finder away, grabs the right club, takes 10 practice swings then waggles over the ball... then duffs it 30 yards or shanks it left 120-130 yards down..  Rinse Repeat.

Needless to say i dont play golf with Mike much anymore.. He just dosnt get it..

It is a serious question but only for those with a knowledge of mathematics which excludes some of the above responders.

It is not a serious question, no. C'mon.

Your rangefinder is held about 6' above the ground, too, and your ball is on the ground. So "rangefinder to flag" is the same distance - within the accuracy margin for a laser rangefinder - as the ball to the hole.

      Day 24 (4 Dec 25) - Spent about an hour working with the new 55° wedge in the backyard.  Kept all shots to under 20yds.  Big focus - not decelerating thru downswing and keeping speed up with abbreviated backswing.  Nothing like hitting a low flighted chip with plenty of check spin and then purpose to float a pitch of similar distance.

      Day 114 12-4 Put some work in on backswing, moving the hips correctly, then feeling over to lead side. Didn't hit any balls was just focused on keeping flowy and moving better. I'll probably do another session tonight and add in some foam balls.

      Didn't say anything about your understanding in my post.  Well, if you are not insisting on alignment with logic of the WHS, then no.  Try me/us. What do you want from us then?? You are not making sense. You come here and post in an open forum, question a system that is constructed with logic, without using any of your own and then give us a small window of your personal experience to support your narrative which at first sight does not makes sense.  I mean, if you are a point of swearing then I would suggest you cut your losses and humor a more gullible audience elsewhere. Good heavens.
