Very true, I have an HP48GX, still haven't learned to program it. I use the
HP32SII, which are very easy to program but only has 384 bytes of memory.

Davy Jones has at least (5) five calculators that I have supplied. I finally
learned NOT to carry them on deck.

I like the programming part it, reduces my ENTRY errors. Just re-did my HP
celestial calculator The only thing I have to do manually is the sextant
correction, calculate the intercept distance, and plotting. I alway fill out
a cheat sheet just as I did when I used H.O. 208 for sight reduction.
