My Lowrance LCX17M has a 7" screen and it's big enough to read the enhanced lake maps I downloaded from Lowrance. I use the split screen when I'm trolling but I have it mounted the on grab rail over my console so I am real close to it. I rotate it to face the front when I'm crappie fishing and then I'm about 7-feet from it so I use the full screen for sonar.Originally Posted by deep-v
