saltwater Posted September 27, 2015 Report Share Posted September 27, 2015 I use my underwater camera to help find fish and to see the topography. Of course, most of the fresh and saltwater here in south Florida is very clear down to 40 feet or so. The camera helps to target individual fish, leaving the undersized or unwanted species. Also, the camera is a learning tool where I can watch the behavior of the target fish. How they react to different baits etc. Quote Link to comment Share on other sites More sharing options...
smallmouthaholic Posted November 14, 2015 Report Share Posted November 14, 2015 (edited) With side scan imaging on today"s sonars you can see what's out there on either side of the boat for 80 feet. Now you tell me which one is easier to find fish with. It's like trying to peer into the darkness with a pen light versus a flood light. Ben According to the Lowrance techs- side scan only goes out as far as the bottom depth.EG: if the water depth is only 15 feet ,the side scan is only useful for 15 feet.I have a Gen 2 touch 12'' and 7'' on the boat. Kindly correct me as to how the side scan is useful out to 80 feet in shallow lakes. I agree that the high tech electronics have made it much easier to find the off shore high spots/humps spots w/ side scan and down scan.Marking and returning to a a GPS waypoint is so easy and accurate. edited for spelling Edited November 14, 2015 by smallmouthaholic Quote Link to comment Share on other sites More sharing options...
RayburnGuy Posted November 15, 2015 Report Share Posted November 15, 2015 I'll admit getting the math wrong, but the exact measurements have little to do with the point I was trying to make. At a depth of 15' with a cone angle of 20 degrees a conventional depth finder is covering a 5' diameter circle. That's still a far cry from 15' on each side of the boat using side scan.
