A laser range finder is a device that measures the distance to an object using laser technology. It emits a laser beam that reflects off the target and returns to the device. By calculating the time it takes for the laser to return, the range finder can determine the distance with high accuracy. These devices are commonly used in various fields, including surveying, construction, and outdoor activities like hunting and golfing. Laser range finders are typically compact and portable, making them easy to carry and use. Many models feature digital displays that show the measured distance instantly. Some advanced versions can also calculate angles and provide additional data, enhancing their functionality for professionals in fields such as architecture and engineering.
