Choosing the wrong sprinkler is the most common reason irrigation systems waste water and leave dry spots. In this guide, we break down the three main sprinkler types and where each one performs best.
1. Spray Heads: Small Zones, Fast Coverage
Spray heads deliver a fixed, fan-shaped pattern with a radius of roughly 1.5 to 5 meters. Because they apply water quickly (high precipitation rate), they suit small lawns, narrow strips, and shrub beds. Pair them with rotary nozzles to slow the application rate on slopes and clay soils.
2. Rotors: Large Areas, Uniform Distribution
For zones larger than about 5 x 5 meters, rotors are the professional choice. Gear-drive rotors such as the Hunter PGP (7.6–15.2 m radius) handle typical residential and commercial turf, while extended-range models like the Hunter I-25 and I-90 cover sports fields and parks with radii up to 21.6 m. Their single-stream rotation applies water slowly and evenly, reducing runoff.
3. Rotary Nozzles: The Efficiency Upgrade
MP rotary nozzles fit standard spray bodies but rotate multiple thin streams, cutting the precipitation rate by up to 70%. They are ideal for retrofitting older spray zones with runoff or pressure problems, and for odd-shaped areas that spray heads overspray.
Quick Selection Checklist
- Zone under 5 m wide: spray heads or MP rotary nozzles
- 5–15 m radius turf: Hunter PGP rotors
- Sports fields / parks: Hunter I-25 or I-90 rotors
- Slopes or clay soil: rotary nozzles or rotors with cycle-and-soak scheduling
- Match precipitation rates within each zone — never mix sprays and rotors together
Don’t Forget the Controller
A good controller multiplies the value of good hardware. Battery-powered Bluetooth controllers like the Hunter NODE-BT bring smart scheduling to isolated valves, while the Hunter HCC manages large sites with hybrid concurrency and Wi-Fi control.
