I am wondering if the new helix 7 si g4 sonars are going to be better having 1024h x 600v pixel instead of the older models with 800h x 480v pixel. Will the screen size still be a big minis as being able to make out fish using side and down scan as the older models. Just wondering if this will be a big game changer for people like me as it's a lot cheaper than the bigger units that cost like twice as much and more just for a couple of inches and sometimes just one inch more screen size. I am now running a humminbird 899 si which has been pretty good. I know in sonar bigger is always better but some of us just can't afford the bigger ones. So will the pixels make a big difference?
