Laser Distance Measuring Tools are also time-saving tools. They quick measure a room, a building, or any distance that you have a target to point them at.
The Stanley TLM100 goes to about 100 feet.
The Stanley TLM200 goes to about 100 but has greater accuracy, and offers a pythagoras feature. This feature allows you to point at one corner of a building and take a measurement, and then point at the other corner of the same building, and then press the pythagoras button and the TLM will calculate the distance between those two points. It uses the Pythagorean theorem to figure the triangular measurement between where you are standing and the two points and figured the side of the triangle which the distance you're wanting to get. A very handy feature.
The Stanley TLM300 has the same pythagoras feature as the TLM-200, but offers greater accuracy than either the TLM100 or the TLM200, and a measuring distance of about 600 feet!
