i got the lowrance 337 last year and i love it. the split screen is fine by me. thats how i run when navigating, with the sonar side skinny. full screen sonar when trolling. i believe the color display makes a big difference when hunting fish. i can easily tell at a glance what type of bottom (mud, sand, grass,etc...) im over. as far as reading it in the sun, i have know problem. i am a grouchy old man and complain about most everything i buy. not my lowrance though. love it!
