Project two intersecting lines to ensure equipment is level and plumb. Set these leveling lasers on any surface and they'll level themselves within about 4°. They’re often used to align bench tops in shops and labs.

Red lasers are dimmer than green lasers, so they’re best viewed indoors. Those that include a tripod can be positioned up to 46" high.

Green lasers appear up to 10 times brighter than red lasers, so they can be used from farther distances and in brightly lit areas, including outdoors. Use the included magnetic target to make your laser beam easier to see from a distance.

Lasers with a strap or magnetic base can be affixed to flat surfaces when mounting holes are not available. Add a tripod to adjust the height of these lasers between 16" and 51".

No need to reposition these lasers as you work around your room—crosshairs on every surface give you all the reference points you need. They are a good choice for level, plumb, and square applications, such as aligning doors and windows on multiple walls. If you set them on a surface, they level themselves within about 4° and indicate when they are out of level. You can turn this function off when you want to make sure your crosshair is level with something other than the Earth.

Secure them to a tripod using the threaded mount. They come with a magnetic target, which you can mount in your space to reflect the laser beam to increase its visibility in dim conditions and at far distances.

Red lasers are dimmer than green lasers, so they’re best viewed indoors.

Green lasers appear up to 10 times brighter than red lasers, so they’re easier to see outdoors or in bright indoor lighting, as well as from far away. Along with the threaded mount, you can also mount them using their strong magnetic base.
