Hey guys Paul here from Colorado. Just needing a lil help with my si images. Picture doesn't look that great compared to others I've seen online. Like I said it's a Helix 7 Si and currently have it hooked up to my jon boat with a magnetic hull clamp. Have gone through settings for best pic quality. It also has it's own 12 volt power source. Does the transducer have to 100% level? I'm stumped and seem to get good quality images. Tia
