The Dual Laser Rangefinder

On construction sites, workers are often required to measure distances between two high points. The height makes it difficult or impossible to make the measurements with existing rulers or laser rangefinders, which significantly lowers work efficiency. The Dual Laser Rangefinder enables distances between high points as well as angles to be accurately measured from a distance. It uses the cosine law cos A=(b2+c2-a2)/2bc to calculate the length of the third side and determine the distance between two points. Regardless of distance or position, the rangefinder provides measurements for both distance and angle at the same time, greatly increasing work efficiency.
