Thread: Navigation, North up vs. Course up

I don't ever use north up. Seems crazy to me. Who cares which way is north when you are on the lake fishing? I want to see where I'm going when I'm running across the lake toward a creek 5 miles away or toward a waypoint I want to fish. I used to use course up but now HB has an orientation called heads up which is what I use now. Not sure if they just renamed course up to heads up or what. May have something to do with the new Heading Sensor GPS antennae. Not sure.

I like heading up.

Course up for me. Less confusing imo

I prefer North up

This is actually heading up. Course up is when you are in navigation mode.

In the HB chartplotter units....

Any boat speed less than 0.6mph....the GPS antenna cannot verify movement...this is why the icon on the chart view changes to a round circle (donut)...the antenna is waiting for new information from the satillites to know which way the boat moved...

As long as the boat is moving faster than 0.6mph, the GPS antenna has enough refreshed new information from the satillites to show the icon as a "boat shape" and pointing in the direction of the "Course" (direction of travel)...

The "Course Up" setting (in this scenario of speeds greater than 0.6mph) will keep the top of the chart map related to the "Course" (direction of travel toward the top of the display)...

If the boat's travel speed drops below 0.6mph...the GPS antenna no longer has enough new info to discern movement....the boat icon will change to the donut ...and the chart map will spin to orient North (of the chart map) ...to the top of the display...

This is because the HB chart view will always default the chart map (spin the chart)...to North at the top of the display any time the GPS antenna does not detect movement...(regardless of the "Chart Orientation" setting used)...

Therefore setting the unit to "North Up" is beneficial for some fishing methods that need the boat movement to be less than 0.6mph (spider riggin)..

In this scenario (of boat movement less than 0.6mph) ...with the unit set to "North Up" ...the chart map will not "spin" to it's default "North at the top of the display"....because North on the chart map is "pinned" to the top of the display..

Even if boat is traveling in another direction (other than North on the water)....North on the chart map is stilled "pinned" to the top of the display...

--------------------------------

"Course Up" and "Head Up" are great for boat speeds above 0.6mph as both those settings will keep "what's in front of you" to the top of the display...(and each works the same ...except when an AS GPS HS antenna is attached)...

The "North Up" setting can be beneficial when boats speeds drop below 0.6mph to keep the chart map from spinning around ...every time the boat movement drops below 0.6mph...

I have always preferred course up. It makes it a lot easier to zero in on a waypoint. But like Rickie said you have to increase speed a little to be accurate. 3MPH has always worked great for me.

Course up for me!!
