Okay, so I see the Hummingbird Side Imaging and down imaging fish-finder units, and although I have not been out in the Mosquito Lagoon, I did go out in the St. Johns River with someone. Depths were mostly 2 feet, with some 6 foot depths in the center of the channel. For the Indian River and the Lagoon I have a feeling most of the time I would be in shallow water. Although I love toys, I can't believe a side imaging or even a down imaging fish-finder will be of much use. Opinions, recommendations, experiences wanted.
