For extra bird control, the Bangalore Broadside is available with additional bird control options.
A Sreamer Kit is available to complement the gun-shot sounds to further control birds and scare them off your crops.
And should you wish to fit it at a later date, these additional bird control options can be retro-fitted to your Bangalore Broadside Bird Scarer.
Note that the Screamer Kit bird control option requires an external 12V battery to operate (not supplied).
