[CA] [CA11] replacing dual c70's

[mdolesh]

I currently have 2 old c70's on a 2006 290 SeaRay Sundancer. The previous owner intended to used the port side as a chartplotter and the starboard for radar (the radome is installed but was never hooked up). I was thinking of replacing both of them with the Axiom 9RV's but I am wondering if I would really need both? That being said...I have 2 holes and wouldn't mind having 2 screens. I need suggestions on what would make the most sense. Budget is not a huge concern, but we only use the boat for cruising in the Chesapeake and in rivers, not for fishing. Thanks!
