“My initial thought was: wait a second – why would I need a piece of plastics on my wrist with no electronics? What could it possibly tell that I do not know already?. But to be honest, it is a great “notetaker” for the wrist. If you as tactician combines this device with an electronic compass – you suddenly have a very useful tool at hand so to say.
This device keeps track of your compass courses – at close haul upwind, as well as downwind, including startline bias calculations.
The coolest part above all, is when the race has started and the wind starts shifting – then just follow along by turning the Wind Dial – and you will immediately get all the new courses including help for estimating laylines towards your competitors.”
