Best Ive used!
Bought for Radar plotting in preparation for my OOW! bought a few from chandlers before, but the cork really makes the difference in zero slip! great product!

Reasonably good parallel action ruler.
Reasonably good parallel action ruler. Clear plastic with protractor markings printed on the lower surface and not engraved, I expect these will wear off much sooner because of this. Marketed by American company but made in China hence the cheaper production I guess.

Worth the money.
After forgetting my plotting tools at home on day two of chart plotting my instructor let me borrow his just like this. I immediately ordered this one and it greatly helped me achieve more accurate plots for my USCG plotting exam.Don’t cheap out with the ruler and divided/compass set. Get the good pair the first time.

This is something you can easily learn to use. A must for boaters in a situation that you lose nav capabilities. Lays flat in your nav station desk top.

Excellent set! Having the slightly larger parallels is well worth it. Replaced my 12” with this 15” and will never look back. Excellent quality, easy to use and durable.
