The WNDSN Explorer notebook is here.

“Keep a notebook. Travel with it, eat with it, sleep with it. Throw in every stray thought that flutters into your brain. Cheap paper is less perishable than gray matter. And lead pencil markings endure longer than memory.” –Jack London

How right the good man was. There is nothing worse than when thoughts are racing wildly through the mind. Better grab a pen quickly and jot everything down. And when it comes to mental math, it's also a tricky thing. Calculations only become relevant when written down, and for years, Telemeter and Quadrant users have had to do without a dedicated WNDSN notebook to capture their most important calculations.
