Self Correcting Depth Charts
Posted: Thu Mar 26, 2015 3:35 pm
I am considering a new fish-finder but many of the new units with built in maps/depth charts seem to suck in the areas I fish. I have noticed that Garmin and Navtronics maps are often at very low detail levels, especially for smaller remote lakes where little and sometimes no information is available. Even on popular lakes there is clearly missing information such as no contour lines near an island, etc.
I know that with the newer combined GPS/Depth plotters you can add your own annotations. But the systems I have seen only seem to allow you to make text notes like 'caught big bass here" or "saw mermaid sunning herself on this rock".
Is there such a thing as a system that self-corrects? For example: if the chart says there is a nice level bottom at 60 feet, but the depth ramps up to 40 feet over a small hump, I want that the hump would to appear on the chart? If I then drive back-and-forth over the area, I might be able to define the edges of a point, bowl or ridge of ground. All great holding zones.
I guess the next best thing would be a system that allows you to hand-edit the maps to add your own contours?
Am i dreaming?
