Occasionally when I am auto chart live mapping in an area (with my helix 10 mega si g2n) where there is a shallow(er) hump, say 6-8 feet of water, the map in that area turns a dark concentrated color with lighter colors around it.
To correct this I have to make a number of passes over the area and usually it self corrects...but it is a pain and time consuming.
Do others experience this and does the 1.9 update fix this? Perspectives and tips welcome.
