Abstract: An irrigation sprinkler head has an auxiliary nozzle carrier having a nozzle attached to each end thereof. Each nozzle is held on one end of the flexible nozzle carrier. One end of the nozzle carrier holding a nozzle is attached to the sprinkler head to operatively attach the nozzle to the outlet of the sprinkler head while the other end extends from the side of the sprinkler head. The nozzles are rapidly exchanged on the sprinkler head by disconnecting the nozzle carrier and nozzle from the sprinkler head and connecting the other end of the nozzle carrier and nozzle to the sprinkler head without removing either nozzle from the carrier and without the use of tools. The nozzle carrier is flexible and angled between the nozzle holding ends so that the nozzle carrier can flex between the ends thereof to absorb impact without damage when used below a crop line.
