Magnetic target for survey.
You will need magnet for this model there is 1 magnet of dia 8 x 1mm and 4 magnets of dia 5 x 0.8mm.
There are so many magnets because it was to use the ones I had in stock, if you want a model with just 1 magnet of dia 10 x 1mm it's possible, just ask me.
You will also need Loctite super glue.
you will also need 20x20mm self-adhesive targets.
