Very high quality
This is handy when plotting your courses.

It Works
Works good. Made out of 1/8" sturdy plastic (probably won't take bending at all). Wheels seem to grip plotting and chart paper reasonably well. It is about 12.5 inches long so you need a bit of room to use it - especially to keep the wheels on a level, gripping surface. It will go in my chart kit and out to sea.

Good alternative to parallel rule
I prefer this to a parallel rule. It is much easier to use on the smaller format of chart books. It's size and the roller aspect to its operation make it easier to use and less subject to slipping.

Navigation Parallel Plotter
I know its great when my instructor won't stop taking it from me to do plotting. I should have purchased two, one for the instructor and one for me. Great item, Great price. You might need to hide it. ha!

Defective
This device is intended to make accurate navigational measurements. This design can be faster to use than parallel rulers. I have utilized this exact model on my teacher's yacht, and it works great. However, I have purchased three, and returned three. The first was broken. The acrylic ruler was broke in two. The second had 0.5 degree of looseness. The third is also noticeably loose. Unacceptable for navigation. Do not buy.

Not bad
Works as intended but quality not the best. Plastic can warp easily.
