COG is course over ground, I read that in the manual. I'm assume its the heading of your boat? I'm new in learning on these fancy fish finders. I say its based off your GPS position and could be used in a way point in marking fish?
Course over ground calculated by the GPS relative to the ground. Will vary from a compas heading because compass is giving a reading based on direction boat is facing. COG can be influenced by wind or current pushing boat sideways. On the water best use I can think of is in navigating from one point to another. Understanding the difference could keep you out of trouble.

Center of gravity. Tells you if the boat is level

This is why the Course Projection Line disappears when the boat is stationary ... Because the unit's GPS is not determining that the boat's present GPS position (Lat/Lon) is any different from the boat's previous GPS position (Lat/Lon) ...
COG can help you know which direction your boat is traveling without even without knowing your relative awareness of where you are on the Earth ...
In the above depiction ... The boat is traveling 21° from Due North (North is 0/360°) ...

Just saw this one. Interesting... Oh; by the way, I didn't really understand COG. Until now. Good answers... Thanks Rickie. Terry

COG tells you where you are going and where you have been. Much different from where the boat is pointing.Quote:

The COG reading tells you "How many degrees from Due North" your boat is traveling ...
*COG 0° = boat is traveling Due North
*COG 90° = boat is traveling Due East
*COG 180° = boat is traveling Due South
*COG 270° = boat is traveling Due West

A radical example is if you were doing a controlled drift on a river system with the boat pointing upstream. The COG would be your course downstream.
So does COG come into play ,when I mark what I think is a nice Tree pallet bed ,not a ball of shad ...an then go go back an cannot find anything...Been reading forum .Pretty good at marking an sinking structure.But sometimes I cant find nothing .First post Snipey
No.....That would be a different thing altogether....... Maybe start a thread about this.
Jokes aside, I did not know that. If I ever venture out into the salt, this could come in handy. Thanks Rickie! :ThumbsUp
Welcome to the site snipey!! There are many reasons why something like this happens, and you should post this as a separate thread, so your answers don't hijack this thread.Quote:
