Abstract
An elevation range meter is configured to be used in conjunction with a reticle to provide an offset range marking, such as an offset range distance that a target is located over on the reticle before firing. An offset range distance factors in the range to the target and the elevation of the firearm. The elevation range meter has a weighted dial that rotates with respect to the barrel or elevation angle to indicate an offset range marking, such as a distance, milliradians or minutes of angle, from a plurality of elevation range marking columns on the weighted dial. The weighted dial may have a plurality of columns of elevation range markings and the appropriate column for the determined range may be selected to indicate the offset range distance. The user may then locate the target on the reticle at this offset range distance before firing.
