Projects two beams of light, it has one vertical beam, one horizontal beam and a combination of both(cross beam).
It is accurate to around 3mm/10m(±60in), suitable for straightening picture frame, wall decor, getting tile rows and columns straight.
Strong green beam is still clear in bright environments(tested under 80~100lux), much easier to read indoors and outdoors than the red beam.
Self-leveling feature makes it automotically level itself if it's within 3(±1) degrees of being straight, and alerts you when it's not level over 3(±1) degrees.
Manual operation feature allows you to project the beam at the angle you need, simply switch button to the LOCK position and it will stop pendulum.
