I'm sure I'm being more than a little bit anal, but my
fluxgate compass is mounted not far from the chart table and the gps
puck could easily end up less than 3 feet from it.
Zee: I have the
autohelm box mounted a safe distance from my other compasses (and its
fluxgate core is pretty feeble anyway.) And since I drop all sorts of stuff into my
bilge, some of which is plastic, I a non magnetic pick-up tool (basically a
claw that extends from a flexible tube).
It's not a big deal, but if there's an easy way to do it without destroying the GPS, I'd rather take it off.
