Customer Reviews
Used for Navigation class 
2008-02-25
These are well made parallel rules. Fifteen inches is about perfect for a chart folded into quarters. These seem to work a little better than the ones that my class mates used. They slipped less and were easy to walk across the chart.
I would suggest that anyone who spends time on the water learn to use a chart and the proper instruments, beyond the GPS. GPS is a valuable tool but batteries die, and electronics don't mix well with water. Weems and Plath instruments all seem to be very good.
