1:50,000 Scale Stainless Steel Ruler
0-30 kilometers, 0-18 miles, and 15 minutes of Latitude
We designed this ruler for military jump masters planning parachute drops. Since then a number of other military units have found it to be a useful planning tool for a variety of missions.
The front side of the ruler measures kilometers (0-30km, smallest interval is 50m) on a 1:50,000 scale map. Both edges on the front side are marked for measuring kilometers, the zero end is on opposite ends of the ruler.
The back side has one edge marked in statute miles (0-18 miles, smallest increment 0.05 mi.) The other edge is marked for latitude (15 minutes, smalls interval 0.05 min.) This edge will measure latitude directly and longitude when used on a diagonal as with our other lat/lon rulers.
The ruler has a hanging hole on one end.
