GPS Lowrance Elite 4

So.. I've been having trouble with the GPS function on my Lowrance Elite 4 and was hoping for some insights to correct the problem. As you can see from the pic the wave point  at  Stillwater North and the pink trail line do not match up. Following the trail line did lead to a return at launch spot. Following the black arrow on the red line would not take me to where I launched at Stillwater Cove. For those of you who fish out of Stillwater you can see that the trail line and GPS map do not align. The trail line is well north of the cove map. I had set the wave point from my place in Occidental believing that when GOTO wavepoint was commanded the black arrow on red line could be lined up with the cove and followed to the beach. Does  the wave point have to be set on the beach or water in the fishing area for it and the red line to indicate correct direction or am I missing something else?

It could be mislabeled on the map. Was the label "stillwater cove" already part of the map? Comparing your pink line to Google maps it looks like it is showing your path of travel in the right place. It looks like the label is wrong and the gps is working.

Stillwater cove is the  factory map label so it would have to be a set up error from the factory if wrong. The problem for me is that pink trail line does not terminate on the cove beach but on the bluffs north of the cove and onto the land despite seeming accurate when following it back to land. May be a glitch in the software or maybe user error but I need help in figuring out which.

Do you mean waypoint?  Not sure what you mean of wavepoint.

Sorry. Way point is what I meant.

I assume it is the base map. That's probably why they say not for navigation. I think the gps is fine. The map is just low resolution and not perfectly accurate. Compare the outline of the coast to google maps satellite view and you will see how much detail is missing. Consider upgrading to the navionics map. 

I know the area pretty well and the base map corresponds to the land configuration accurately enough. The Navonics option on the Elite shows the same land masses but without Hwy 1 crossing over the cove.

Another example is my humminbird base map. In the google image below we see water. My base map would show me on land. Not because of user or gps error. The base map just doesn't show the detail that water is there. When I upgraded to a navionics map card my gps showed water where before it showed land.

I accept that google earth makes  finer distinctions but last year while fishing out of Timber Cove the base map, the way point and the guide arrow all aligned to point the kayak back to point of launch. I have a hard time accepting that the base map could be off as much as it was at Stillwater last Friday.

It is possible your signal was blocked? I don't know about the view of the sky from where you were. If you can download the pink track to a computer you could convert it and load it into Google earth. That could help you determine if it is drawn where you actually were.

My skill set with electronic devices and their programs is severely limited so no go for that although it sounds like a good crosscheck.

If you can't get the answer I could maybe help if you could get it saved from the FF. Keep in mind any map that shows highway 1 crossing water where there is no bridge does not inspire confidence in its accuracy.

Thanks but pink trail bird nest  was deleted.

Hi Charles,
I believe both the map and the GPS are working properly.  Google Maps and Google Earth both label the cove just south of Stillwater Cove Regional park, where the "Glass House" is located, as Stillwater Cove.  Not sure how or why the naming seems off, but Google Maps has the same location of "Stillwater Cove" as the Lowrance.  See attached.
