Do I need a slope on my rangefinder?

The slope is useful when measuring distance on a rangefinder. Golfers should practice with slope features on their rangefinders. Using slope while practicing can improve a player’s game.

A rangefinder calculates slope by measuring the distance between two points. The laser sends out a beam of light and returns after bouncing off the object. The time difference between sending the beam out and receiving it back tells how far away the target is.

How do hunters measure distance?

Laser rangefinders work by sending out a beam of light. The faster the beam travels, the farther away the object is. A laser rangefinder measures how long it takes for the beam of light to return. The longer the beam stays in the air, the further away the object is.

What does the angle mean on a range finder?

Bow hunters used to be able to estimate distances by looking at the terrain. Nowadays, we have laser rangefinders that help us measure distances more accurately. We still need to know how far away our target is, but now we can do this without having to guess.
