The C. Attwood pocket trig log tables are the smallest published trig tables that I have ever seen. 6 places gives 0.1' precision. Having loads of fun doing CN the old way with this table. Warning...even 20/20 vision may require reading glasses. Copies show up on ebay from time to time. Keep an eye out.
