Spectra QML800 Interior 2-D Layout System Kit

The QML800 QuickMark Layout system comprises of two high-resolution line lasers controlled by an upgraded Nvidia tablet. The two lasers communicate, in wireless mode, with the tablet. The system calibration consists of aligning the two lasers together and defining an origin point and a scale.

The point from any map can be entered easily using CAD drawing export or CSV file export. Once all the points are uploaded on the tablet, the user simply selects any point and the lasers rotate to create, within few seconds, a bright visible X where this point is located.

There are many possibilities to select a point either directly from the map or by entering its coordinates or even from the list of points previously uploaded.

It is fast, efficient and very easy-to-use. Complicated shapes, arcs and curves are now easy to layout with no calculations required.

Days of layout now become hours. Accuracy is also improved and more importantly, errors are not compounded from point to point. As a result, layouts can be completed before the other trades arrive.

Spectra Precision says the system is accurate to within 3mm across the entire floor being laid out. In testing, they found that the system reduces labour hours by 56 per cent. In fact, they put the system to the test by asking one crew to lay out 225 points with the QML800 and another with the traditional method. The crew with the QML800 finished the job in two hours while the other crew was only able to layout 64 points! Beyond that, the crew without the QML800 made 5 errors while the crew with it made none.

Spectra Precision says these kinds of errors only compound and can ruin a whole job. The QML system allows crews to see whether all of the points will fit within a given floor from the beginning because it measures from the plans rather than from point to point. 

All-in-all its a fantastic layout aid for the Professional Interior Contractor!

I have worked in the construction industry for over 25 years dealing with hundreds of suppliers, the quality of their products is fantastic, the delivery is next day so you can't complain about that and the customer service is second to none, if you need a leveling tool don't bother going anywhere else.
