Played with my old Lowrance LCX-17M w/navionics this afternoon on boat Lake Talquin selected and got much better info than your pic at same location. my unit as it was set up was much the same as yours but playing with the setup the contours looked much better. Haven't been on Talquin in years but got the Navionics chip to fish the Crappie.com super slabfest there.--shu
