Re: [PSUBS-MAILIST] Rudder position indicator

["Alan James" <alanjames@xtra.co.nz>]

Hi Marc,
Had to look up what it was on Wiki
http://en.wikipedia.org/wiki/Hall_effect_sensor
I knew them as proximity sensors.
I wonder wich would be the most reliable or cheapest?
I had a dive torch with a magnetic switch that wasn't that reliable,
& potting the Hall effect sensor seems easiest.
