Wow Dave. I asked this about a month ago and got no responces! I have been looking at the Aqua vu and the Atlantis. I want to use mine for downriggering, crabbing, shrimping, jigging ling or halibut, rivers, etc. I have really found no input for anything. Atlantis makes a good one too. Also Walker downriggers has one made onto the downrigger. The best Atlantis one has a pan to move the camera around. With downriggers the cable thickness will be a hinderance to the drag of the water. I understand you will be at three rivers. I will see you there and talk to you about it. I have been trying hard to read up before purchasing. Hereis Atlantis website. Grandpa has put it on his post. http://www.atlantiscamera.com/
