Pickett N600-ES Pocket Slide Rule

Description

This slide rule is said to have gone to the moon with Buzz Aldrin on Apollo 11.  Because of this, it's know sometimes as the "Apollo Rule."   This, of course, has made it very collectible, whereas it becomes hard to find a copy for less that $50...MUCH more if it comes with the original box, case, and documentation.

Assessment

This is one of the smallest rules I own.  It has a durable feel, albeit the numbers can be a bit hard to read.  The cursor does feature a convex lens, which magnifies the numbers at the hair-line ever so slightly.  

Like most typical rules, I don't care much for the eye-saver yellow as I don't find them easy to read, especially the red fonts.   Even so, it's an iconic slide rule.
