- Basic SAR Skills Manual: Ch.7 "Navigation"
Aids
Outline
Material Covered:
Navigation - section 3 - compass use and exercise
Objective:
* 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 * review: UTM * bearings on map exercise: see /home/wuth/sar/pc/training/subject/navigation/map/map.txt * triangulation
Duration: 2 hours 15 minutes
Aids:
SAR Fundamentals - Chapter 13 - Navigation Tape Measure Slides:
Plan:
1/ Review past material
Give sample UTMs, find elevation Give sample UTM pairs find bearing relative to True North
2/ discuss Magnetic Declination
*** show Slide Basic SAR 501
Where needle points
Reading declination from map (add grid N)
North pole moves - currently moving north about 40 km / year
Calculating from map - minutes in a degree
Magnetic declination for Pincher Creek, 2003: 16deg 36' E. according to http://www.geolab.nrcan.gc.ca/geomag/mirp_e.shtml
Adjusting declination on compass
3/ shooting a bearing with a compass
using compass - avoid metal - avoid magnetic fields
holding compass sighting
reading bearing
walking a bearing - how far to look
4/ Pacing
slide: step vs. pace
counting your pace
calculating distance from paces
calculating paces from distance
5/ Exercises: bearings
hand-out: Pacing and Traverse
