For a consol unit I prefer the external. That way I can position the reciever as close to the transducer as possible. This should give a truer mark.

I look at it like this. If I have a 20' boat and I have my transducer on the stern and my reciever on the bow, I'm starting out with a 20' error. Closer the better.
You bring out some good points. Bottom line is you want the antenna as close to the transducer as possible.
