HBirds come right off the base very easily. Mount a second base in the front and just move it from console to the bow when you fish. The splitter you mentioned, Y cable, is at least 20 bucks if I remember right, an extra base probably aint much more. Just another option and then it would be easier to see the screen.

Cabelas has always had better electronic prices for me then BPS. Can always get their credit card to get the 50 or 100 dollar instant discount and then cut the card up when it comes in the mail.

You'll like the down image and the color. I couldnt go back to black/white screen.
