i have never seen anything like that in winni ever. champlain is crazy, truth is that might be perch and not smelt or something else i don't even know about.
It will look like that if you get into them but just not as big. i think that is in 50 khz which is a wider beam and shows bigger clusters than if you were running a narrow 200khz.
i run them both, usually at 50 it will lock onto my downrigger balls and call them bottom and i get nothing, but in champ i run faster speeds and they drift back and don't mark as bottom and 50 covers a wider angle with some loss in definition. in winni i am almost always on 200 also i run the gain at "Auto Hi" play with it that C80 has more options and settings than anything i have ever seen.
