Main version also featured no optical rangefinder.

The turret had an optical rangefinder.

It had the TPD-2-49 coincidence optical rangefinder sight protruding from its turret.

With a laser beam and an optical rangefinder system, the device instantly measures distances between 33 feet and a half-mile.

The debris caused by the passing shell killed one officer and five enlisted men, and destroyed the optical rangefinder for the forward 150 mm turrets.

The X-shaped motor and optical rangefinder were both discarded due to performance, and the accuracy of smoothbore gun continued to be unsatisfactory.

Michael Taylor began using an optical rangefinder and Suunto clinometer circa 1993-94 using the sine method.

An additional search periscope and radar PPI was provided as well as an optical rangefinder in the reserve command post.

Though Italian warships lacked radar, this was partly offset in fair weather by Italian optical rangefinder and fire-control systems.

For these cannon, a four-story concrete director tower was built near the eastern shore of Duncan's Cove with a long-range optical rangefinder installed on the top floor.

C Co 2/66 Armor surprised the competition by placing with its old M60A1 tanks, which used optical rangefinder technology from the World War II era.

To do this, it had optical sights (the rectangular widows on the front), an optical rangefinder (the tubes sticking out each side), and Fire Control Radar antennas.

The fortified battery was armed with three Elswick 6 inch naval guns with associated searchlight, director tower, generators, a long-range optical rangefinder and by 1943 a radar artillery control unit.

Deke hit some more buttons to bring the optical rangefinder into sync with Zoomer and noted the read-out: distance, three miles; altitude, twelve hundred feet; estimated airspeed, fifteen to twenty miles an hour.

Among the new features were an increased tower height and stability for the optical rangefinder equipment (for gunnery control), more armor (especially around turrets) to protect against plunging fire and aerial bombing, and additional anti-aircraft weapons.

The modernization included placing the search light on the right-hand-side of main armament, blanking off the TPD-2-49 coincidence optical rangefinder and fitting of rubber skirts protecting the tracks instead of the flipper type armor panels.

The gunner has a dual mode (day/night) 1PN22M1 6x/6.7x magnification image intensifying monocular periscope sight, four day-use periscope vision blocks, an optical rangefinder and an OU-3GK removable infrared or white-light searchlight.

According to some sources, the similarities between the E-50 and the E-75 went further; they were to be equipped with the same turret and 88mm L/71 or L/100 gun, along with an optical rangefinder for increased long range accuracy.

In World War II, a height finder was an optical rangefinder used to determine the altitude of an aircraft (actually the slant range from the emplacement which was combined with the angle of sight, in a mechanical computer, to produce altitude), used to direct anti-aircraft guns.

On 11 August Renault was contacted to build a full scale wooden mock-up of a vehicle capable of accommodating the ER26 ter and R14 radio set, a large number of telephone cable connections and on top an optical rangefinder turret with a base of 160 centimetres.
