Q&A

micro LM-400 Advanced Laser Distance Meter is rated 4.5 out of 5 by 8.

Rated 3 out of 5 by BritReese from Unable to connect Bluetooth I bought this tool because I found the Ridgid Sketch App first. The App itself is awesome and the features are great tools What I do not like is that I can not get this unit to pair with.....anything. Two different iPads - 3 different iPhones. Nothing. So I have to read back on its list of measurements and then manually add them to your “sketch”. Essentially, this thing is a brick to me...a $192 brick. I reached out to Ridgid support, I have received ZERO response, this is upsetting, as I have purchased just about every 18v tool or stationary wood working tool that Ridgid has produced.

Rated 5 out of 5 by Freetooler from A very good tool for interior measurements. The screen shows which measurements to take as you go through the steps for square, cubic and height. I was able to use the tool accurately within a few minutes.

Rated 4 out of 5 by grady95035 from The tool feature packed, software needs work The product itself is good and packed with features costing more on competitive products. The software, Rigid Sketch, could be the differentiator for this product with some minor improvements. First off, the measurements are rounded and displayed to the nearest inch despite the tools ability to measure within 1/16th. File management of drawings is non existent and editing drawings is awkward and often impossible. I have spoken to tech support and they are making an internal request to fix the display accuracy. Leica provides a tool that provides the display accuracy but fails to scale the drawing as dimensions are added. As a stand alone tool, 5 stars. If you plan to use Bluetooth to transfer dimensions to Rigid Sketch, unless an inch accuracy is close enough, you will find the tool useless.

Rated 5 out of 5 by Tomika from Godd thing It's a good instrument, very easy to use. The Bluetoth data transfer works good, i like it. To send the measure dates to an Android phone is very easy. The Ridgid sketch program with the photo feature (sending measuring data on a photo) is excellent.

Rated 5 out of 5 by GoPastTheLimit from Amazing Product I bought this product months ago and it has been the most accurate that I have ever purchased in the last ten years. It's very durable as I have dropped it many times but it definitely is a product to consider.

limited ability to display accurate measurements on Rigid Sketch

Why do you build a laser measurement tool with accuracy to the 1/16th of an inch and provide a companion software tool that rounds measurements to the inch? This makes this nicely designed piece of software effectively useless for any form of construction. Are there plans to modify the tool such that accuracy to the 1/16th of an inch will be displayed?

Asked by: grady95035

Okay precision, and whether it is useful for use in the area of construction and maintenance in general. But I think if measuring horizontal angles would be better, because now only measures vertical angles and only up to 65 °. thx
