Abstract: An optic device turret for adjusting the optical element of the optic device with at least two knobs that are each movable between a first position wherein the knob is not rotatable and a second position wherein the knob can be rotated. The access to and rotation of both knobs can be accomplished without the use of tools. The rotation of each knob adjusts the optical element. A spiral cam mechanism is engaged with the turret to define a maximum and minimum adjustment of the optical element. A rotation indicator displays the amount a knob has been rotated.

Abstract: A reticle for an optical sighting device, such as a riflescope, has subtension markings of varying thicknesses and scales to accommodate both stationary and moving targeting.

Abstract: Rifle scope turrets with spiral cam mechanisms include a scope body, a movable optical element defining an optical axis enclosed by the scope body, and a turret having a screw operably connected to the optical element for adjusting the optical axis in response to rotation of the screw. The turret has a spiral cam mechanism engaged thereto. The turret defines first and second stop surfaces positioned for engagement by the spiral cam to limit rotation of the turn The first stop surface defines a zero position of the screw and the movable optical element. The second stop surface defines a maximum point of displacement of the screw and the moveable optical element. The stop surfaces may be defined by a spiral cam groove in the indexing portion of the turret. The groove may overlap itself at least partially. The turret may be an elevation turret or a windage turret.

Abstract: A rangefinder having improved display capabilities. The rangefinder has a ranging system, a processor, and a display. The rangefinder may have a multi-position button for inputting data, and may also have an inertial navigation unit. The rangefinder has improved input and tracking of wind direction and speed, allowing for improved ballistic compensation for wind.

Abstract: A dual focal plane optical sighting device, such as a riflescope, having two reticles, one of which is an electronic reticle. The optical system has an objective lens system, an eyepiece lens, and an erector system, with two focal planes, a first reticle at the first focal plane, and a second reticle at the second focal plane, and at least one of the reticles is an electronic reticle.

Abstract: A cover for use with an optic device to hold and display shooting information. The cover may have resilient retention members that allow a display to be releasably attached and detached from the cover. The display may be made from a single substrate or multiple substrates in order to make the shooting information contained thereon highly visible in a variety of conditions and shooting preferences. The cover may include a flexible body for securing the cover to optic devices of a variety of sizes.

Abstract: A dual focal plane optical sighting device, such as a riflescope, having two focal planes, with a first reticle at the first focal plane, and a second reticle at the second focal plane. The reticle at the first focal plane is a glass etched reticle; the reticle at the second focal plane is a wire reticle. The two reticles have different patterns or markings providing the appearance of a single reticle or complementary markings when viewed through the optical sighting device.

Abstract: A reticle design is disclosed for use in the first focal plane, which can be used both for close range and long range shooting. A phosphor luminescent material or other type of visible reflecting material is used with a diffraction pattern to enhance the brightness or visibility of all or a portion of the reticle, and may be used alone or in connection with other ways of illuminating the reticle.

Abstract: Rifle scopes with adjustment stops include a scope body, a movable optical element defining an optical axis enclosed by the scope body, and a turret having a screw operably connected to the optical element for adjusting the optical axis in response to rotation of the screw. The turret has a stop element selectably engaged to the screw. The body defines a stop surface positioned for engagement by the turret stop element to limit rotation of the screw, such that the relative position at which the stop element is secured to the screw defines a zero position of the screw and the movable optical element. The stop element is held against the stop surface by an indexing portion while the relative position at which the stop element is secured to the screw to define the zero position is determined.

Abstract: A monocular with attachment points has a tubular frame with a hard point attached to its exterior an optical axis defined by its center axis. A clip may have one end connected to the hard point. There may be two hard points attached to the frame's exterior, and the clip may be operable to detach from and reattach to either of the hard points. The hard points may be arranged in pairs on opposite sides of the frame's exterior. There may be a hand strap operable to detach from and reattach to any of the pairs of hard points. There may be a mounting surface rigidly connected to the frame's exterior. The mounting surface may be parallel to the optical axis and operable to receive a tripod mount and a picatinny rail mounting plate.
