You get what you pay for but it is especially true when it come to decoys. With calls one doesn't need to spend alot of money to have a good one for hunting. WingLock call are one of the best for ducks and my personal preference in canada goose call is Faulks. They sell for about $20 and $7 respectively.
In decoys G&H or Herters are the low end. Stay away from Carry Lite and Flambaue decoys. If you're limited to only a few decoys here in the northeast I prefer blacks over mallards ,but thats in this neck of the woods.
