Need Help Choosing New Lowrance Unit(s)

[muskybones]

Hello,
I have a Ranger 620. I have been running 2 Lowrance 104c units since I purchased the boat in 2005. Well, one of the units stopped working and I am looking to upgrade. I will continue to run the one 104c that still works as my depth finder at the bow. I am mulling around the idea of getting a Hds-10 or two Hds-7 units at the console. The Hds-10 would be split screen for navigation and sonar. The two Hds-7 units would have one dedicated to navigation and the other for sonar. At this time, I am not interested in the downscan or sidescan stuff. Maybe at some point in the future that stuff will interest me, but it can be added later.

Thanks in advance for advice and opinions.
