Curious as to how far different gunners normally set up off to side of their decoy spread when gunnin scoters. Set up couple days ago in slick calm conditions with rig of homemade y boards and sleds. Had no problem at all attracting birds to spread but bulk wanted to pass at about 60 yds or so. I had boat blind set along side of rig about 20 yds off closest string. with 2 long strings deployed about 20' apart. Did manage to kill a few at the 40 yd mark but just wasn,t happy with the way they reacted to boat blind positioning. Also tried setting at head of rig but birds would split rig even a little farther away. Any suggestions?
