The Stanley Fatmax FMHT77448-1 is used for large construction work, such as installing drywall. The 360° line laser has a horizontal, vertical and a cross line, but also a 360 degree horizontal line. This gives you a laser line that shines all around and is therefore visible across multiple walls. Thanks to the receiver you have a large working range of 600 meters. The green laser line is more visible than a red line. The laser is self-leveling with a range of 8 degrees. This automatically aligns the line laser. With the remote control you switch the various functions on, for example the scan mode, on or off.
