Laser rangefinders are used in golf to measure the yardage of a particular shot but also to gauge slope and wind as well. There has been debate over whether they should be allowed in tournaments. While their use is banned on the professional level, they are becoming widely used on the amateur level.
A laser rangefinder, also known as a laser telemeter, is a rangefinder that uses a laser beam to determine the distance to an object. The most common form of laser rangefinder operates on the time of flight principle by sending a laser pulse in a narrow beam towards the object and measuring the time taken by the pulse to be reflected off the ...
Rangefinders allow a golfer to measure exact distance to the hole from their current position; they are illegal according to Rule 14-3 of the rules of golf, but the USGA allows individual course clubs to institute a local rule permitting rangefinders, and they are common among recreational golfers. The typical rangefinder is an optical device ...
A stereoscopic rangefinder or stereoscopic telemeter [1] is an optical device that measures distance from the observer to a target, using the observer's capability of binocular vision. It looks similar to a coincidence rangefinder , which uses different principles and has only one eyepiece.
Coincidence rangefinders work through the principle of triangulation. In the pictured example, triangulation can be used to determine the range of the ship 𝑑.The position of the lenses A and B are known, and the angle of the lenses α and/or β is set by the operator so that both are aimed at the target.
The slope rating of a golf course is a measure of its relative difficulty for a bogey golfer compared to a scratch golfer.It is used by handicapping systems to equalize the field by accounting for the likelihood that, when playing on more difficult courses, higher handicap players' scores will rise more quickly than their handicaps would otherwise predict.
With the start of a new year on Jan. 1, 2025, comes the emergence of a new generation. 2025 marks the end of Generation Alpha and the start of Generation Beta, a cohort that will include all ...
A depression position finder measured the range to a distant target (such as a ship) by solving a right triangle in which the short side was the height of the instrument above mean low water; one angle was the constant right angle between the short side and the plane of the ocean, and the second angle was the depression angle from the horizontal of the instrument as it sighted down from a fire ...
