Sonars?

[spinmaster21]

So I'm looking into picking up a new ice/boat fishing sonar. I currently run an older Lowrance elite and want to upgrade. My questions are, is there a sonar that can be used as both an ice sonar and then be used effectively in the boat also? Or should I just get a sonar for ice fishing and a separate for my boat? What sonar do you run and why? I thought there was a previous post about this but wasn't able to find it. You're expertise and knowledge would be greatly appreciated. Thanks!
