this is the 4000 series, you need to go with the 5000 series for touch screen. I did not want the touch because i commercial fish alot and did not want fish gut hands on the screen all the time!
IA remember fishing with nothing and it was something to get a corpus! then the loran, and my first gps was a handheld, no charts, we have come a long way!!
this unit was $2000 at the boat show a few years back, with radar, sounder, and gps. I an very happy with it!!
