Hi,
I have a Garmin 2010C with a shoot through the hull transducer now, the transducer works fairly well and I keep the boat (21' center console) in the water with bottom paint.
Can I expect similar performance from the shoot through the hull transducer attached to an 1158C?
Can I start with the same through the hull transducer on an 1198, then add the transom mount later for side imaging?
One challenge I face is getting the boat out of the water, it's not easy for me until winter so deferring the external transducer is a plus.
