1694228[/URL]]Personally I would go with 2 x 9" because the way I use my chartplotters is one on nav chart and one on sonar. With the 16" you would end up with (in theory) 2 x 8" which is nothing to be sneezed at, but if one fails you don't have any backup. I believe you are in Tasmania. Where you fish and how far from land etc, a failure may not be as big a problem as fishing the Great Barrier Reef, where we are always looking to find new marks or going to old marks while working around shallow reefs and dodging reefs to get out and get home. I do like your new boat that 's on the way.
