Don't know why i never thought of checking vs gps. So easy,I was reading about navigation points and plotting vs the chart. Btw i do try to use my compass all the time. I also use my radar on nice days just to get used to what stuff is supposed to look like. At some point on my boat or on some one else's I may need to know those things (I fish Chatham so fog on the cold tide is a normal occurance) and it's better to have it not be the first time you see what another boat looks like or the tip of monomoy .

i never used mine for real navigation, I just used it to see what way I was drifting and would take a reading when I left the dock so I could find my way back in the fog. Did not care if it was right or wrong, just went with what ever it gave me.
