Thread: Rangefinding

Yes, shoot it, then take a waypoint of where you are standing with the gps. Walk over to the dead animal and then get the gps to tell you the distance back to the waypoint.

If you want to find out the range before shooting it then use the gps to make up a range map i.e. that hill is 600m and the tree in front is 400m. The deer standing half way between the hill and the tree is then logically 500m

Of course this assumes the deer is at the same elevations as you. If not, these is a little more maths to do to get a true horizontal distance:

If the deer is below you and at an angle of 15 degrees (measured using a app on your phone or inclinometer.

You need to use the Cosine of the angle and apply this factor to the distance above. Looks like this:

COSINE of 15 degrees is 0.9659, or 95.59% of the slope distance measure above:

636.8 x 0.9659 = 615 yards.

This is the distance that the the force of Gravity will effect the path of you bullet.
