Locate changes of direction, if any, at the checkpoints picked. Get the total distance to be traveled and the approximate distance between checkpoints. Plan to use the vehicle odometer to keep track of distance traveled. Use the pace count method and keep a record of the distance traveled. When using a pace count, convert from map distance to ground distance by adding the conversion factors of 20 percent for cross-country movement.
Mental notes are usually adequate.
Try to imagine what the route will be like and remember it. Plan to Avoid Errors. Restudy the route selected. Try to determine where errors are most apt to occur and how to avoid any trouble. When the routes have been selected and the navigator has divided the distance to be traveled into legs, prepare a logbook.
