Subject

What is this lesson plan about?


This is a short 1-hour practical training on taking and following bearing with a compass and pacing distance, to be done outside in an open area.

A small student to instructor ratio (max 5:1) is recommended. As such, this lesson is often one station of several with a larger class broken up into smaller teams of max 5 students and this session is taught repeatedly by the same instructor as the teams move between stations. See "Search skills and compass practical" as a commonly used example of this lesson as one of several stations.

What is included in this lesson, what's not and why.

SAR Fundamentals Manual: Ch.13 "Navigation"
Basic SAR Skills Manual: Ch.7 "Navigation"
  • Navigation - section 3 - compass use and exercise

Prerequisites

What should students already know/have accomplished before the lesson is presented.

Prior to this lesson, students should have already been introduced to the following concepts:

  1. identify cardinal directions
  2. identify directions in degrees

See "Navigation - map - direction" for the lesson plan that provides these prerequisites.

  1. the parts of a compass
  2. how a compass works
  3. how a compass fails
  4. declination

See "Navigation instruments theory" for the lesson plan that provides these prerequisites.

Objectives

At the conclusion of this lesson the participants:

  1. will be able to ...
  • know cardinal directions
  • know compass degrees
  • know what affects a compass
  • magnetic declination
  • shooting a bearing with a compass
  • pacing
  • exercises:
    • bearings
    • pacing / bearing
  • backbearing
  • offsets

instructional points in normal font

aids, exercises, activities in italic

1/ discuss Magnetic Declination

  • Where needle points
  • Reading declination from map (add grid N)
  • Adjusting declination on compass

2/ shooting a bearing with a compass

  • using compass
    • avoid metal
      • belt buckle
    • avoid magnetic fields
  • holding compass
    • hold flat
  • sighting
    • using mirror
    • using sighting notches
  • reading bearing
    • rotating barrel
    • "red to the bed"
    • parallax problem
      • parallel needle edge, not needle in the middle
    • practice reading bearings to several objects
    • vary distance and note differences in error
  • walking a bearing
    • setting bearing
    • how far to look
    • practice finding destinations at several bearings

3/ Pacing

  • Step is one foot to the opposite
  • Pace is one foot to the same foot (two steps)
  • counting your pace
  • measure your pace in 10m
  • calculating distance from paces
  • calculating paces from distance

4/ Exercises: bearings

  • hand-out: Pacing and Traverse

5/ Advance

As they come up in discussion, describe:

  • back bearings
  • offsets
