I feel like my Helix 7 SI is very pixelated and is not nearly as clear as the demo screen shows. I am on a sand bottom lake and am not sure if that has anything to do with it but even big railroad ties don't show up :/ The transducer is clear of any obstructions too. I noticed posts about trolling motor interference but mine looks the same whether the trolling motor is on or off. I also tried messing with the contrast and all of that and then also reset factory settings, none of which helped.20180617_190805.jpg Here is a pic of what I'm seeing.
