I'm not really sure about the Aqua View..but 2 years ago I went to Al and Bobs Sports and rented one...I caught my limit of gills using this unit. I'd watch the fish suck in the tear drop without even moving my very sensitive spring bobber and when they did it, I'd pull straight up and I'd have em.
I always thought the sonar from my Lowrance Fish Finder would spook fish, but with todays technologies I know for a Fact using my Vexilar Pro: I can see fish come right to my bait and then I focus on my spring bobber..I'll have em shortly...So, the sonars don't bother them now..
I also use the Auto Lock system I have and can get a fish that's 1/2 inch off bottom to come up and take my bait.
Happy fishin..
