We offer two emitter options for your Field Irrigation Kit. Which one is right for you? In general, if you have lower water pressure, 10 to 25 psi, we recommend you choose the Wobbler. If your water pressure is between 25 and 43 psi, the Meganet is the one for you. For more detailed information about each sprinkler head, refer to the data sheets for the Meganet and Wobbler on the Tech Specs page.
