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 or use the strong magnetic base to attach them to equipment. 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.

Align guide rails or lay pipe at specific angles from a flat surface. The laser light is red and is best viewed indoors. The display shows the precise angle of the beam and rotates for overhead measurements. The audible level indicator tells you when the tool is level and plumb.

Align rotary shafts with the help of a mobile app. These sensor kits are more accurate than straightedges and easier to use than dial indicators. Properly aligning shafts reduces vibration and protects couplings, bearings, and other parts from wear and damage.

Use the included chain clamps to mount these sensors above your coupling, where they detect the degree of misalignment between the shafts. The app shows live animations to give step-by-step instructions for repositioning your equipment. Once the shafts are aligned, the app saves a report documenting the process.

Good for extended use in industrial environments, these sensors last up to 18 hours between charges and are IP54 rated for protection from dust.
