An internet search will bring up a number of devices people have created to help when calibrating a DistoX2, mostly these seem to require the use of a 3d printer or a trip to the local plumbing store. I have made a rotary cradle out of some scrap plastic material that allows the the heading of the Distox2 to be maintained whilst rolling the unit to collect the required shots for calibration to be performed.
It is two discs (cut on a lathe whilst sandwiched and bolted together so they are exactly the same size) which clamp around the outside of the Disto body. The front has a large hole for the laser and the rear has a small hole in which the rear reference point is to be aligned with.
Before use the front end (whilst maintaining the position of the reference point to the rear) must be moved so that the laser exit is inline with the centre of the circle of plastic. This was done via trial and error, the jig and Disto was pointed at a wall around 4 m away and rotated until the laser described as small a circle as possible (nearly a dot) on the wall.
Once satisfied I then collected the 56 shots required for calibration. I prefer doing this in my garden, i’m yet to get better results using targets on a cave wall.
Once the shots have been collected they are grouped then analysed in Topodroid, i’m very happy with the results and would definitely use this jig the next time I calibrate the disto
