    Thanks Gary and Frank,
    
    very useful links. Calibration down to one degree sounds good enough to 
    me for navigational purposes (plenty gyro compasses do not achieve this, 
    you will need a fibre-optic one for better results). The Shetland 
    Islands (due west from Bergen) were frequented by the Vikings in the 
    past, which takes two days sailing. I always wondered how they managed 
    to sail due west for two days to get there. The Sun-Stone can very well 
    explain how they did this.
