This is why I appreciate this forum. I really wanted a DI unit but after hearing all the issues I waited and got the Elite 7 DSI combo which will display both 2D and DI and Gps charts. You can overlay the 2 images or split the screen and compare the two. I am not sold yet though, because I just got it on my boat and have not had time to play with it much. I like the big screen though. I went from a 3.5 HB 385 to a 7" DSI. Big change!
I paid just over $600 from Brian at BBG Marine, one of our CDC sponsors.
