Abstract
A telescopic sight having objective lenses, intermediate lenses and an eyepiece is provided with an adjustable reticle device which is disposed in the second focal plane intermediate the eyepiece and said intermediate lenses. The adjustable reticle device is provided with a fixed center line reticle and two identical moveable reticles located on opposite sides of the center line reticle. The moveable reticles are each supported by a carrier which is moveable in two orthogonal directions by means of two threaded stems carried by the body of the adjustable reticle device. The stems are each provided with knurled knobs each of which has two arrows thereon disposed at right angles to each other on the side of knob facing the shooter so that the shooter can readily determine the direction of movement of bullet impact upon rotation of a knob in any specific direction.
