I could use any advice that you guys could offer. On my fish finder, it has a setting for fish symbols, or for the fish to be displayed as arches. If I set it for fish symbols, I can't tell if I am marking bait or bigger fish. (I have it set for various sizes also) If I shut off the fish symbols, the fish alarm goes off and I see a gray blur. I am yet to see it display an arch like the manual says. The fish finder came with the boat and it is in grayscale. Am I just inexperienced, or should I just go buy a color fishfinder? Or is there something else I am doing wrong?
