GPS Heading and Compass heading - Kayak Fishing Adventures on Big Water’s Edge

wiredantz · 06-01-2011, 10:13 PM

Does anyone have any idea why the GPS on my fishfinder would read differently than my two compass.

Example my fishfinder would say that the Artificial reef is directly ahead of me at 212 degrees as i am paddling at 2.5 mph

I then looked at my two compasses and compass will say 190 degrees same direction i have a humminbird 161. I don't remember very well i have to test again i just remember that the GPS Heading was wayyyyyyyyyyy offfff
