I bought an old Sestrel compass, in the center of the compass, sticked on the window there is a small plastic black box filled with electronics .What it is this electronics ?
What is the meaning of qubbins?Can I remove it from the compass glass without damaging the glass,it seems to be only sticked by a sort of Sikaflex Thanks
here its a circuit board sealed in Sikaflex,6 thin wires are coming out of the black plastic box stuck in the middle of the compass glass.Do you think I can dismantle the plastic box without damaging the compass.
