used for plotting DR (dead reckoning) positions. seems a bit of overkill with 10 points, but could be useful in restricted waters plotting 3 minute fixes. you would also get nearly immediate feedback on set & drift. just my guess…

Some charts only have degree, minute & seconds markings. With these dividers you can mark in thenths of a degree which most people find easier to plot.

YES, they are 10-point dividers. So what can we use them for these post-loran days??

And yep, I know they actually have 11 points, but none-the-less, for some reason they are called 10 point dividers.

They are called 10 point dividers. We used to use them a long time ago for LORAN-C TD plotting (instead of the now familiar card).
