The Ebbco gets a new casio calculator watch/stopwatch ($15) modification and becomes the lightest sextant kit in my CN arsenal. Warning...the Casio calculator watch requires using the edge of a fingernail to enter numbers and functions. Time is easier to set on this model because the digits are typed in without the need to scroll. Trig requires a 4 place natural trig table at eight pages 5"x7". The Casio calculator watch will also attach to the scope of a Davis Mk 15 or 25.
