c) BEARING COMPASS!
The bearing compass is an absolute necessity.!
Some called mini-compasses are so small they can be!
carried around your neck and they are very efficient.!
Some are also installed on binoculars and are very!
convenient for long distance sightings.!
d) PARALLEL RULE!
The parallel rule is absolutely necessary and!
should be accompanied with a divider (etcher's points).!
e) CALCULATORS!
A scientific electronic calculator is invaluable!
for navigating. One of them, the NC-77 by "Tamaya" sold by!
"Weems & Plath" (£100) has navigation tables and nautical!
almanac values for the sun up to the year 1999. It is a!
very fast way to translate a sighting. They are very!
expensive and you must still know how to translate a!
sextant sighting. You must still purchase the nautical!
almanac each year and still have the tables on board!
since, if the unit ceases to function, you will have to do!
it manually.!
f) NAVIGATION BOOKS!
You must still have the tables H0-214 and 229 and!
the current nautical almanac on board.!
