In this case, but you can use a conventional ruler and the rod of a ballpoint pen. By setting a ruler on the plane parts and attaching the rod, mark the position of its upper end on the scale. Then, putting down the rod into the hole, again, look at the position of its end on the scale: the difference between the counts will indicate the hole depth. Measurement accuracy at the same time — to polukilometre, and with good eye even higher.
