I was at Cabela's today getting ready to pick up a new down imaging depth finder when I decided to ask the salesman about what the image looked like while sitting still. He quickly told me that Hummingbird recommends a minimum speed of 2.5 mph for the down imaging to work. I decided not to purchase it. I was looking more for the "real picture" of down imaging while sitting still or close to it. He stated that he has never personally used one so I thought I would ask on here. If you have down imaging, what do you think about it, how slow can you go with it, etc. My personal use would be more for sitting on top of brush piles etc. so sonar would be better, right? Do you have any sitting still images from your down imaging depth finder?
