in clay target shotgun shooting learning, games and competition, which
can be set up and operated in any location of the field. A preferred

transport in any position of the shooting field a multi-target release
control panel, a portable safety screen that is carried, positioned at
each shooting station to assure safety of the shooting, a plurality of
mutable station indicators that can be placed randomly on the course and
a release cable assembly that connects the clay target throwing machines
to the multi-target release control panel. Further a pivoting arm clears
the way for the mobile support device by guiding the cables. Additionally
a hulls collection box is attached to the portable safety screen and the
mobile support device, helping to maintain a clean field.
