How accurate are laser levels?

Professional models are accurate to +/- 1/8 inch at 100 feet. Budget models are accurate to +/- 1/4 inch at 30 feet. For hanging pictures and cabinets, budget accuracy is fine. For tile installation, framing, and professional work, invest in a professional-grade self-leveling model.

Can I use a laser level outdoors?

Laser lines are invisible outdoors in sunlight beyond a few feet. For outdoor use, you need a laser detector/receiver mounted on a grade rod. The detector beeps when it hits the laser beam. Rotary lasers are the standard for outdoor work. Budget cross-line lasers can work at short range on overcast days.
