This is the only course that you need extra materials.
You need to get the Long Island Sound Chart. Chart # 12354 to perform the real exercises.
You can get it inside the course by downloading for free the hi res large file PDF. You can then take that to your local printer and for about $15-20 they will print it out.
Alternatively for those in the USA, you can get it from us via Amazon below.
Option (1) Includes the chart, a set of compass dividers, and a Breton Rotating Protractor.
Or you can get the chart itself alone.
