    micro emergency sight reduction champion. 

    So size does matter afterall! (small is beautiful)

    see my post from Nov 2014 . My minimalist lit includes the Otis King Plus micro trig tables. Can do cosine formula to 4 decimal plasces or Bygrave or use it for the multiplication step in the Doniaol. . The Otis King is 6 " long when folded.

    Best wishes

    Francis
