# Range Finder Silly Question

Ok, so I finally bucked up and bought a range finder after many years of walking off distances and guessing how far away I was. First, it was a bit humbling to see how far I actually hit the ball...and second I am looking for clarification on how they calculate distance.

Let’s say I lock onto a flag and it says I am 150 our, does that calculation take into effect the height of the flag stick? I assume it does because otherwise we’d all be overshooting distances.

For reference I have the Bushnell V4 Tour

356so if you were to shoot the flag, you're actually aiming 2-3 yards higher than you actually are.

if that's the case then no, a basic range finder will not calculate that difference, it is purely to measure how far the device is from the particular point you are pointing at.

Unless you're talking about a raised green haha

That's an interesting question, i never thought about that, but i'm also not nearly accurate enough for that to affect my thinking hahah

2,668✭✭A spin-off of what you're asking, but I'll just add that the most valuable benefit I've gotten from my rangefinder purchase several years ago was getting a much better feel for how far I hit my irons (I was also quite humbled). However, I now make better club selections than I used to, I'm sure of that.

18✭✭This is exactly what I'm trying to figure out, do I need to subtract that 2-3 yards off the distance reading to get an accurate number? I also am not accurate enough for it to make a huge difference but it would be nice to have the number dialed in.

2,159✭✭The length of the flagstick from where you are has no implication on yardage. The rangefinder shoots out a laser and once it hits an object (flag, tree, car, house, ship, person, whatever) the laser will bounce back to the range finder and it calculates the straight yardage from there. If the rangefinder has a slope feature, it will make a further calculation and give out its perceived or "plays like" yardage.

A little Pythagorean Theorem does the trick:

sqr(100^2 + 10^2) ~ 100.5
