Sorry, forgot to answer the other question. Yes, this is for external wiring; for the wiring from my bubble attachment to the sextant handle. Even trying to be gentle and not flexing the wire at cold temperatures only goes so far. Eventually, the wire starts to crack and then I have to replace the damn thing. Oh hell, why don't I just pull out the Garmin and forget about it all??? (I'm only kidding). Why fully tinned wire? What is special about that stuff?
