Johnson 40-6535 Electronic Self-Leveling Horizontal Rotary Laser Level is the most popular electronic self-leveling rotary laser due to its 2,000' diameter range and accuracy of 1/16" per 100' versus its cost. This rotary laser level is primarily an outdoor laser level and its best application is determining elevations from a known point of elevation or instrument height. It comes with a detector but you'll want to accessorize with a aluminum grade rod.
