Hi Jing, Welcome aboard. I now use a Casio fx-3650P.Wrapped in a waterproof plastic bag. I have programmed 4 calculations into it; Works easily and perfectly. degrees in decimals or minutes/seconds, no problems, can mix as well. Very seaworthy and robust in plastic bag. (Mine also kept in a metal box (Faraday cage)to protect against lighting or nuclear strikes!) I also have a old Texas TI-36XPro which can take 1 pre-program, I have standard (single)modern time sight on mine. Best wishes and good luck. Francis
