I am new to this forum. I have a question about quadra beam shoot thru hull transducer XP 9 QB 90 T. From Humminbird website, this transducer is "FOR USE WITH" a list of non-SI fish finders. If I buy a SI fish finder without transducer (e.g. 998c SI combo CHO), and this XP 9 QB 90 T transducer, mount it as shoot thru hull, can I get Side Image?
Another question is, what's the minimum boat speed to get Side Image?
