Sun and Map Instrument Suppliers

Celestaire, A source for Davis #063 Course Protractor #4402 @ $6.00 or Davis #071 3 Arm Protractor and C-Thru #1500-15 Clear Parallel Rules #4306 for $6.95. You only need one protractor and parallel rules for map reading. They also have many books on navigation, mapping and history.

The Celestaire 5" Square Protractor # 4405 and a clear plastic ruler with line from end to end in its middle will make a accurate clinometer. Just add a small bolt or tack with an eraser in the middle and a counter weight to the bottom of the ruler. (See Homemade Clinometer)

C Thru Ruler Company,, makes two course protractors: #CA-9 Grid Compass Course Protractor for $8.50 and #255A 360 degree Compass Protractor with Arm for $2.50. They also make #1500-12 Folding Parallel Rule, 12". Also handy are #259 4" 360 degree Circular Protractor 4" for $1.50 or #255 360 Degree Protractor for @1.10. Get 2 or 3 of these circular protractors for a sundial and homemade clinometer. They will advise you of their dealers.

The C Thru #CA-9 Grid Compass Course Protractor will also make a good CLINOMETER. Just add a weight to the arm, replace the center grommet with a small bolt and calibrate where the weight goes with a level. (Buy two because one will be on your map.)

Local nautical navigation suppliers will also have the course protractors and parallel rules.
