I am considering a Bumper Boy Derby Double with the image and motion control to simulate retired guns. I am seeking feedback from anyone that has the motion feature and whether or not it truly appears as a retired gun. The "retired" effect is achieved by swiveling the image 90 degrees. Just wondering if it really works, or is the image visible if you are not looking at it dead-on. When the dog moves to the mark it seems like he would easily see the gunner image and the "retired" aspect is lost. Thanks.
