Work great for radar plotting
Standard navigation triangles. Work great for radar plotting, chart plotting, etc. A must have tool for any mariner.

Easy peasy
Who knew you need one of these things until you take a class and discover it's something that you really need. You can line up items easily through the clear acrylic because the lines are there and. . . it makes something that once seemed very complicated and uncertain, easy and clear.

It works
It’s an old way to measure the angles. It’s a lot easier to use than parallel rulers

Good, but ain't what they used to be (2)
I agree with other reviewers, they are not stamped into the plastic like mine were years ago when I sailed as a mate (now wearing out). But now as a landlubber, I still find these indispensable, but not for navigation. If you need a straight edge often, these are the most versatile desk tools I have (I got the version with inches). I should add, they come in a heavy duty plastic storage pouch - not useful on a ship, but great for storing in a desk drawer.Highly recommend.
