GPS Orientation

Hmmm... I read charts/maps with North Up. 'taint no other way they make sense. But I use the GPS in Heading up as I want to follow the contour lines while fishing and it is simply easier to correlate the view outside to the GPS when zoomed way in. Plotting courses however will mean setting it to North Up again.

GPS Chart Plotters are North up. Great for true and relative references from the paper/book charts that most people have on board. My primary plotter is my GARMIN 2006c with the fish finder.

The RADAR is heads up and marvelous aide for collision avoidance with Nav Aides, bridges and the many uneducated 'weekend' boaters. Best of both worlds. Here the RAYMARINE C80 RADAR with its chart plotter is the backup and a wonderful cross check.

If you have the C80 Chart Plotter with an Auto Pilot, I have encountered a heading error on this plotter due to a Flux Gate error which was not immediately apparent when I left the dock due to heavy traffic around the piers. The Standby compass & Garmin brought this to my attention and I had to 'swing' the compass before I ventured across the Ches. Bay with Auto Pilot, etc.. Now I cross check my instruments more faithfully than before, just as when I was flying crew in the ASW aircraft with the USN.

Art, get rid of the details....

Same as Mike on "Levity", north up except if I don't know the area or have had too many beers!

When planning, plotting routes, etc. I always look at charts in North Up mode. However, years ago working on fishing boats we did a lot of radar assisted navigation. I learned to orient the chart heading up so that the picture on the radar screen and the chart could be more quickly compared. I guess it stuck because now I like running with the GPS chart in heading up. And the same still applies regarding comparison between the electronic chart and the image on the radar screen.

Hi everyone,

We have one of the new Garmen plotters with the built in coastal maps. I can work everything EXCEPT changing to course up. Most of the time I like North up , but some times like at night the course up would be handy.

Maybe some one could instruct me.

THANKS

What model Garmin? I just installed the 3210 and changed it to display course up. It has soft keys, and one is for Map Setup. I believe it is through that menu where the orientation is set. If it is some model other than the 3200 series, I probably can't help you much.

Now we might have to redo this poll, because Garmin threw another option into the mix. With the new BlueChart g2 cards there is an option to display what they call "mariners-eye-view" which is a 3D mode that is supposed to look like what you see out the window with the sky on top and the water on the bottom. I haven't tried it because my cards aren't here yet, but the reviews I have seen don't give it much value. I guess when in that mode not many of the plotting features work. The new g2 cards also have some other new features one of which is the inclusion of aerial photos of inlets and marinas. Could be cool.
