High power of 4500 Gauss! It does not repel the birds with biological magnet (magnetite) to generate a magnetic field of the tunnel! It is effective in birds you have pigeons, crows, ducks, gulls, etc., biological magnet (magnetite). High power of 4500 gauss powerful magnetic force, I lasted a long time the effect. Rather than interference of radio or television equipment, it is harmless to the human body. Because it does not kill birds, do not have any complaints from bird fancier. There is no discomfort in small and simple in shape, yet painted to match the color of the various outer walls is now possible.
