Who here uses them? Having never targeted them, there's an area that's holding lots this year. Cans, Redheads, & Scaup. We've started changing dekes and would like to try sway them our way. Recommend me a diver call and some tips. Same with Gadwalls. They are everywhere.this year. Mallards are in the area, but we are seeing more Gads and divers than anything right now. I've tried using Mallard hen calls, and would like a call specifically Gadwall, so again, asking for tips & suggestions. Thanks!
