Goertz Range Finder

The Goertz Range Finder was most often used by Air Defense "Flak Artillery" units.

These are two views of the sight picture looking through trees at a tower. Notice the Right has a center layer like view that is not aligned with the vertical line of the red tower. The Left shows the red tower now aligned within the "layer". This is accomplished by moving the range dial. Once you have vertical alignment, read the "range to target "on the display (see the very bottom photograph).

A: Looking at a Tower through the Goertz Range Finder with the range improperly set.

B: Looking at the same tower after adjusting the range dial until the center segment is aligned to the top and bottom of the tower. Once this correctly adjusted, look over to the range scale indicator to the right side of the scope. This figure is the range to the target from your position.


Below is the display for the range to target reading.
