Heres a list of all my favorite "tools" for duck huntin.

duck decoys - greenhead gear
goose decoys - greenhead gear
duck calls - rich-n-tone
goose calls - zink
shotgun - benelli super black eagle
shotgun shells - remington hevi steel ( or hevi shot if you can afford it)
waders - hodgman
jackets and other clothing - drake

these are just what ive used and proved to work for me. but i guess we all have different opinions
