I'm still not sold on if chirp helps much in shallow water.
I tried this today.two 40 millimeter ping pong balls tied to a my marker.the conditions were not so great today, but did give me an ideal of what to expect.ill try again when there's a a day with no wind. (I need to find a place with no fish also) anyhows, these are the pictures from today.About at the 20ft. mark in the center of these pictures is the ping pong balls.Acuallty , the string can be seen two, in one or two of the pictures
