I am heading to Cabelas tomorrow Aug 23to get 2 dozen decoys of the Greenhead Gear Hot Buy Mallards. I have never duck hunted before and I wanted to try it out but as you can seeI don't want to spend a lot. So my question is do I need anchors and yes what ones do I get? I was looking into to getting theAce Decoy Anchors that have the j weight. Are these good ones to get? Also I was thinking of getting a adjustable length decoy retriever pole, is it worth spending the $20. to have one?
