Mathias WolthuisSurveyor · Developer · Entrepreneur
My best ideas come from doing the work. From situations where something could be more precise, simpler or more efficient.
I started in surveying and setting out in October 2014 at HB Landmeetkundige Dienstverlening, where I learned the profession. I also gained experience at Agel Adviseurs, Geonius and L2 Maatvoering before becoming self-employed. That practical experience shapes what I develop through QPROD.
A solution should work well and feel right to use. Functional, reliable and carefully considered, down to the details. My ambition is to make good surveying more accessible through products and software that prove their value in everyday use.

Will my prism fit?
The set includes Leica spigot, 5/8” thread and M8 female and male connections. These support many common circular, 360°, mini and mini 360° prisms, including compatible models from Leica, Trimble, Topcon, Sokkia and Stonex. Check your prism’s mounting connection. Using a different system? Send a photo or specification and we will help you find a suitable solution.
