navionics HD Map of Flaming Gorge

has andbody been using the Navionics premium chip that has 1' contours of the bottom of Flaming Gorge? Just trying to find out if it is very accurate and if the 1' countours are too much detail? thanks

got one and love it. Only thing that takes some getting used too is the chane in water depth that is continually occuring. Bottom contour is correct but depths depend on how much water there is. I think they take measurements from full water line. Last year was close, waiting to see what the depth peak at this year.
