A Laser Range Finder is a device that uses laser technology to measure distances accurately. It emits a laser beam towards a target and calculates the time it takes for the beam to bounce back. This information allows the device to determine the distance to the object, making it useful in various fields such as surveying, construction, and outdoor activities. These devices are often compact and portable, making them easy to use in the field. Many modern Laser Range Finders also come with additional features, such as angle measurement and built-in calculators, enhancing their functionality for users like architects and engineers.
