Here and in some didactical material on nautical navigation I've noticed an advice to use Casio FX-300ES scientific calculator.
Searching where to buy it I see that its' sister model is available: the FX-300ES Plus.
The price is almost the same, the documentation does not specify the difference either. Which one to prefer?
Thank you for advises.
