            Q:How do you measure in fractions? The mode only shows feet and whole inches. Will it display say 7'-5 1/2"? If so how? Have I purchased the wrong measurer?

            A:  Hi Brian! Thanks for the question. GLM 20 X Laser Tool has different unit of measurement like which are meter (decimal) ft/inches and inches (fraction). You just need to off the tool, then press and hold the on off bottom to choose your preferred unit. For further assistance, contact us at 1-877-BOSCH99 (1-877-267-2499) from Mon-Fri 7A-7P CST.

              A:  Hello Brian Yes it should measure fractions 7' 5 1/2"

              A:  This device measures only in approximation, and will not be any more accurate than an inch plus or minus, and that's only if it sends the laser beam exactly to the same corresponding point across the room as the point it is placed. That means that part of a mis-measurement is user error, and the other point is the loose tolerance of the device. If exact measurements are necessary, you should use a tape rule.

              by|Jun 7, 2020

                A:  Yes, it displays for instance, 2' 7" and 1/2"

                by|Apr 25, 2019

                  A:  The unit I have which is the Bosch Blaze GLM-20 shows fractions by 1/16 on an inch. The fractions appear on the lower right side of the screen next to the inch mark. You need to look at the display head on or you will not see the fractions since they are much smaller & lighter.

                    A:  It would work to the surface of the sealer. It would not penetrate the sealer

                    by|Jan 6, 2021

                    A:  Probably will work because of the viscosity and color of the driveway sealer. I have tested this with water in various types and colors of vessels and it did not work.

                    by|Nov 9, 2019

                      A:  If you are trying to measure the width & length of a driveway then the black top sealer has nothing to do with it. I you are trying to figure out how much sealer to buy in order to cover you driveway you need to figure out the area of your driveway. To figure this out stand at one end of the driveway with this device place a flat board at the other end do this for both the length & width, multiply the two measurements & you have the area. The container of sealer will give you coverage area.

                        A:  Thank you for the question. The GLM 20 or other Bosch Laser Measurer is designed to measure pointing on solid surfaces.

                          Q:Does this measure linear square ft. Thanks

                          A:  I am unsure what you mean by linear square feet. If you measure the length and with of the room you can calculate the square feet. by simply multiplying the two measurements. So if the room is 10x10 feet, that is 100 square feet. A 12x12 room would be 144 square feet.

                            A:  Not to my knowledge. It only reads out the distance from the back end of it to the red dot projected to the opposite surface.

                            by|Apr 20, 2019

                              A:  No, it just measures from point A to point B. It will save the previous measurement though.

                              by|Feb 23, 2019

                              A:  You have to multiply 2 linear dimensions in linear feet to obtain an area in square feet. The blaze measures lines and from there, measuring to sides of a rectangle, you can obtain the area. It cannot do it automatically.

                              by|Feb 24, 2019

                                A:  Thank you for the question. The GLM 20 X unit of measurements are M(d), Ft/In and in(f).For further assistance, contact us at 1-877-BOSCH99 (1-877-267-2499) from Mon-Fri 7A-7P CST.

                                  by|Feb 21, 2019

                                  A:  Linear. You would multiply length times width for SQ feet.

                                  by|Feb 25, 2019

                                    A:  It works just like a regular tape measure only without the tape.

                                                                A:  It will measure the distance between the laser device and the exact point the laser hits the sloped ceiling. So, you might need to move the laser several times to get all the measurements you need. The device is easy to use- since it's digital, the measurements will display on the screen as you move it closer/farther from the distance you are measuring. Hope this helps.

I place the device on the floor beneath the point on the ceiling I wish to measure and put a level beside it to insure it is vertical (I use my phone level) and push the measurement button followed by the hold button. The measurements are accurate to the laser point on the ceiling. I hope this helps you with your project. Sincerely, hamrdul

Measurement takes place at the center of the laser beam and it starts from the bottom/rear of the device, even when target surfaces are at a slope.

There is a small loop on one end of the wrist strap, feed the loop through the "U", and when the small loop protrudes through the end, feed the other end of the wrist strap through the small loop.
