<\/p>\n\n\n

In order to create an accurate plan of an old house, I purchased a Leica X4. It is a robust, pleasant instrument, clearly designed by engineers, for engineers and the build quality is faultless.<\/p>\n\n\n\n

My first pleasant surprise was that each device is comes with an individual calibratation certificate and the tolerances are much tighter than the blurb in the spec-sheet:<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

As it should be, the deviation tolerance (\u00b12\u03c3) is supplied at a specified temperature, with tolerance (\u00b13\u00b0). Second pleasant surprise, 0.2mm at 7.8 metres is 0.002% – this is clearly a laboratory-grade instrument. <\/p>\n\n\n\n

Indoor measurements are made with the red laser dot, outdoor measurements can also be made using the builtin zoomable camera, both very intuitive<\/p>\n\n\n\n

The quick-start guide is about as terse as can be – essentially useless for more than using the device as a tape measure – you’ll need to download the manual<\/a> to be able to make use of all the X4’s features; it is well-written and easy to follow. It took me a good half-hour to become capable of making every measure possible, they are extensive:<\/p>\n\n\n\n
