A very accurate navigational tool and very handy for those not too quick at counting on your fingers! ;-) Slightly over sized for the application that I need, however don't let that put you off purchasing. Nice an robust.

Die Rechenscheibe erfüllt ihren Zweck ohne Probleme. Ob ich sie wirklich brauche? So schwer ist der Dreisatz ja eigentlich nicht. Wer aber nicht gerne rechnet, kann dies mit der Scheibe einfacher erledigen.
