I've noticed a lot of birds do a "fly by" within range rather than commit to land like they did a few years ago.
I did ok before I used the Mojo but I have to admit that on the few occasions this year that I killed the battery on it, I didn't feel as confident. One thing about the Mojo, we hunt an area with mountains on both sides of us. I believe we miss a lot of birds that fly by before we see them because of the trees. The Mojo attracts some of these birds and they give us a look rather than flying by. I'll use the Mojo as long as it's legal too.

P.S. I use magnum decoys too....
