These are the best set of dividers I have ever owned and it makes my life easier when I am in the air. They are really simple to figure out how to use and are very precise.

These are a good set of dividers! Every navigator should definately have a pair! They are sturdy and the friction knob works perfectly, keeping your distance travelled without pinching. The distance versus velocity is great too! The needles on this thing are sharp and accurate. Not as good as the pointers of the product from 10 years ago, the needles on those set were flat and far superior. Dont get me wrong, these are still good, just not as good as 10 years ago. If you can get your hands on those, I would recommend, but these will work nearly as good.- C-130E/H Navigator!
