Is an integrated instrument for determining angles of inclination or slope. It measures the equivalent horizontal distance to the target. This feature is very handy at golf or long-range inclined shooting because both – golf players and shooters need the equivalent horizontal distance and not the actual distance. This is because of the gravity of the earthworks on the flying object only this equivalent horizontal distance that is traveling to the hole or the target. If the golf player or the shooter doesn’t take this into account, the ball flies further and the bullet higher.
