I purchased a Pickett model N902-ES "slipstick" from eBay. I remember having a slide rule around the house when I was a kid, but this has been my first 'real' experience with one. (Not counting the flat Bygrave.)
I am enjoying learning how to use it immensely. Seriously, this thing is way handy. I just tried running through the formulae for determining a DR from the N.A. (L1=Lf+t(v/60)sin(T)/cos(Bf), etc.) My results were remarkably accurate!
I'm now one step closer to surviving the E.M.P. apocalypse. :P
P.S.
Is there any way to figure arcsin/arccos on the average slide rule. Or is that why Capt. Bygrave invented his rule?
