Display indicating aiming point relative to target size indicator
An improved display provides information regarding a projectile trajectory so that a user is informed whether or not there is a clear shot. In some embodiments, an intermediate point in the projectile trajectory is an aiming point and is indicated in relation to the visualized target or target reference. The rangefinder device is calibrated to a weapon having a sight, for example, having a riflescope calibrated at 100 yards. The aiming point is displayed showing the intermediate point in the projectile trajectory that corresponds with riflescope cross hairs at a predetermined zero setting. The user places the riflescope cross hairs on the point visualized in the rangefinder device. Alternatively, the aiming point is displayed relative to the magnified image of the target, a generic reference image, or a user selectable reference images.
