Rain Bird’s copper-colored subsurface emitter tubing with Copper Shield™ provides 90% watering efficiency， right at the root zone. Rain Bird’s patent-pending Copper Shield Technology protects the emitter from root intrusion， creating a long-lasting， low maintenance sub-surface drip irrigation system for use in organic gardens or shrub and groundcover areas. Having the copper color outside ensures the copper chip is inside and that your dripline is protected from root intrusion.
