The tightly sealed water outlet minimizes leaks to maximize water use efficiency and irrigation effectiveness. Use scenarios: Watering borders and garden beds in small to medium yards by selecting 90° or 180° to target plants without waste. Expanding irrigation for large lawns or multiple garden zones by connecting multiple units in series to meet coverage needs. Permanent or semipermanent inground use in grassy areas, where the spike holds the sprinkler in place for hands operation and efficient watering.
