Range cards
Place each stage's firing position and targets on the map. Yards and azimuths (degrees magnetic) work themselves out; a laser reading replaces the map yardage. Your work is kept in this browser only, so export a file to keep it or move it to another computer.
Drag any pin to move it, even while adding targets. Tap a pin for its wheel: fine adjust, lock, details, remove.
