I am a long time lowrance user. Lowrance's switch to C-Maps had me concerned but one month in I am very pleased with the mapping. The 9" screen is great for keeping open a map and also watching the depth/fish finder
I would definitely recommend this unit as a reasonably priced GPS/Fishfinder/Sounder.
The built in chart sucks as it doesn't give actual numbers for depth. The different colors for depth don't do me much good when I'm fishing rivers. So I had to but an SD card for a chart that gives numbers
