April 11, 2016 / no comments, on Reviews

Bosch GSL 2

The Bosch GSL 2 is a interior laser tool that checks the levelness of a floor surface allowing the user to mark any highs or lows and so making fixing the problem far easier than traditional methods.  The Bosch GSL 2 is designed for Concreter’s, Tilers and other specialist installation applications to enable them make highly accurate level floors quickly.  However you check for level now on your internal floors this tool is far, far quicker.

It works by projecting two laser line onto the floor in a “V” formation with the bottom of the “V” being one single line along the floor if two lines start to appear then the floor is not exactly level and the wider the two lines are apart the bigger the dip or crest on the floor.

The Bosch GSL 2 rotates on its base so you can quickly sweep around the room to check all of it from one location.  There are two versions of the Bosch GSL 2, one which you manually rotate and another that has a motorised base and remote control.

The Bosch GSL 2 comes with a target plate that helps you determine wether you have a dip or a crest in the floor and extends the usable range in brighter conditions.
