Bosch GSL 2 Professional Floor Surface Laser

Check floors quickly and completely - all on your own.

The Bosch GSL 2 floor laser is a revolutionary floor scanning tool that provides a fast, easy, and accurate way to check if a floor is flat and level. This Bosch laser is ideal for any independent tile contractor, composite floor layer, drywall installer, or site surveyor who needs to quickly and reliably check floors for surface irregularities.

Here's how it works: The floor laser projects two red lines onto the floor; if the floor is flat, both lines will appear exactly on top of each other. However, if the floor is uneven, two discrete lines will be visible, indicating that that area needs to be addressed.

Surface Laser Features

  • Projects two laser lines that meet on the floor surface to determine level and flatness
  • Bright, clear laser line projection – allows laser lines to come together when surface is flat and level and separate when surface is uneven and out of level
  • Target plate shows how much deviation (depression or elevation) exists from predetermined reference point
  • Motorized rotary base – offers continuous view of floor surface instead of spot checking
  • Versatile battery operation – can be used with either alkaline batteries (included) or Bosch Lithium-Ion 12V MAX battery pack (not included)
  • Operated by RC 2 remote control (included)

Advantages of Bosch GSL 2

  • One-man job - eliminates the need to remeasure or have someone nearby to help; huge surfaces can easily be checked by a single person using the remote control
  • Precise - easily see surface irregularities (high and low spots) with 100% reliability
  • Total coverage - the GLT 2 completely assess floor surfaces within a 60 ft. radius in just a few minutes

How to Use

  • Step 1: Set up the floor laser for measurement in a central location, then turn the unit on.
  • Step 2: Set the height according to a reference point - then set it so the two laser lines are exactly on top of each other.
  • Step 3: Check flatness - Rotate the laser's head (manually or by remote control) to check the entire room. Elevation or depression exists in any part of the floor where the operator can see two individual laser lines instead of only one.
  • Step 4: Check deviation - Place the target so that its metal pin is directly over the surface irregularity. The path of the laser lines on the scale will indicate the deviation.

This Laser Is A Time saver!

by - verified purchaser
This is the only floor laser tool that helps make floors flat and level. The difference between using this tool versus a straight edge is that the floor can be made not only flat but also level. It doesn't take a lot of time or skill to use this tool whereas it does if you use straight edges.

It came in a rugged toolbox I have seen them sold for around $65. The tool itself weighs around 2-3 pounds. In the box were the remote control, target plate, and batteries and insert for the tool.

This tool works by using two lasers that together show elevations and depressions in a floor. As flooring contractors know it would be necessary to get down with kneepads and use a straight edge to check for elevations and depressions. It is a requisite to get the concrete subflooring as flat as possible because If the subfloor isn't flat, the tile can pop or the adhesive can loosen over time. Flooring professionals know about all this and use additional bonding materials and grinding machines to fix such problems.

Great tool Highly I Recommend For All Flooring Contractors!
