Patent ID: 7535553

Claim:
A device for determining a range to a target, the device comprising: a range sensor for determining a first range to the target; a tilt sensor for determining an angle to the target relative to the device; and a computing element, coupled with the range sensor and the tilt sensor, for determining a second range based on the first range, a precalculated factor based on the determined angle and golf ball flight characteristics in air, and scaled based on the first range where: when the first range is less or equal to a first threshold value, the factor is scaled by a first value; when the first range is between the first threshold value and a second threshold value, the factor is scaled by a second value; and when the first range is greater than or equal to the second threshold value, the multiplier is a third value, the second range being a representation of a flat-ground distance the projectile must travel such that the projectile's trajectory intersects the target.
