Customer Questions & Answers

Is it able to do indirect length measurements?

Asked by: Rich
No. However the GLM 40 X does have that capability and is much smaller then the GLM 40.

will it work outside with a distance over 100 feet

Asked by: jd48455
This meter is spec'd to measure to a 140 feet linear distance. With that being said, I will add this comment. Measurements made outside in bright sun light can be a tricky task. The problem is, the laser spot, even on a white surface tends to be difficult to see, therefore, it can be hard to see what you are actually measuring too. The meter is able to see the reflected beam, and as long as the beam has a clear path back to the meter, and is within it's range limits, it can perform the measurement...

140 ft. Laser Distance Measurer is rated 4.7 out of 5 by 140.
Rated 5 out of 5 by from Powerful tool in small package Fantastic product. I had a window sill I had measured prior to buying and this unit measured it exactly to the mm! I reckon for distances under 3m this thing is more accurate than stated by Bosch.

Rated 5 out of 5 by from Compact, Accurate, High Quality I use this to create floor plans of existing buildings. It's the quickest and most accurate way to measure in my opinion. I've been super impressed with the quality and reliability of this tool.

Rated 5 out of 5 by from Accurate. Fast. I am a Steamfitter/pipefitter and bought this unit as I do a lot of work by myself. It is quite accurate and the measurements are good enough to be able to give them to a welder to build. It takes a little bit to get use to pushing the button when in awkward places. I like the fact that it measures from the back of the unit. Like any tool, if you don't take time to check you are measuring from the right place, it won't work well :)) I am hard on myself and hard on my equipment, so it is good that the Bosch tools are tough enough to stand up to my work.

Rated 5 out of 5 by from Awesome accuracy! For certain jobs, room area etc, this is a tool that everyone should have. Accuracy is great and speeds up the measuring tremendously.

Rated 5 out of 5 by from Don't know how I did my job without it! I have owned this tool for over two years now and couldn't get along without it. As an engineer doing field investigations or evaluations alone, I often need to take awkward measurements without any help. This tool is easy to use, make switching between units easy, and has proven very accurate and reliable. It also allows measurements beyond what most tapes will do and without the benefit of outside light.

Rated 4 out of 5 by from extremely accurate but I found a glitch great product and was very happy to find you can measures in inches instead of just feet and inches like the 35' measure I was using before. I did find a glitch in the software though, when using inches to measure and accessing the memory it would show the results in meters. switching to the default ft in would work properly though

Rated 3 out of 5 by from Display Made too many bad cuts caused by not seeing the fraction in the LCD due to it was barely light. It finally dawned on me that all my measurements couldn't be all even numbers! A lot of wasted lumber! Could have bought the next higher model if you add all the bad cuts!

Rated 4 out of 5 by from Works pretty well For measuring distances to loud speakers (something impossible to do with a tape measure), this is a good tool. I wish the display was visible through a greater angle, but since it save the measurement, that is a fairly small matter.
