Topic: Interference?

[FlatsFokker]

I've been thinking a lot about high speed depth readings. I know I can get the shoot through hull ducer but I really dont like the idea of the 898 using the thru hull while scanning.
If I were to get the in dash depth reader(HDR 610 with thru hull ducer) would I have a prob with interference on the 898?
I'm really not concerned with high speed scanning,just trying to avoid running aground in the bay.
