Picked up a Marcum M5 last year but never got a chance to use it much until this season. I am really enjoying it, but notice that no matter what size of a lure or jig I use, it shows as 2 distinct lines. I am not sure if it is separating the knot on top with the hooks but it is odd. Are marcum flashers that sensitive to be able to pick up that much detail? I was using an ice 35 previously and never had this issue.
