Easy and Flexible Programming: This garden sprinkler supports a wider range of run times and interval settings. Watering times range from 1 second to 99 minutes, and watering intervals range from 1 hour to 15 days. This allows you to fully customize your watering schedule. This irrigation timer can be used with drip irrigation systems, sprinkler controls, pool filling, and sprinkler systems. (Hose connection: 3/4 inch internal thread; Outlet: 3/4 inch internal thread) Integrated Large Screen and Over 6 Months of Run Time: The 3-inch ultra-wide HD screen makes everything clear at a glance. Furthermore, if the drip hose timer remains inactive for 30 seconds, the screen automatically enters sleep mode, saving significant power. A powerful chip detects low battery and shuts off the hose timer before the battery runs out. It uses only two 1.5V AA alkaline batteries (not included). Smart Power and Versatility: A smart display shows the remaining battery level, keeping you informed of available power. Manual mode allows for immediate watering without interrupting your set watering program. The rain delay mode pauses your program for a period of time, preventing over-watering and unnecessary waste, saving a significant amount of water on rainy days. The child lock mode prevents children and pets from accidentally operating the sprinkler timer. Manual mode provides precise time display. Waterproof and durable: IP65 waterproof rating, tested under 10kg water pressure, and features a new pneumatic sealing assembly that greatly reduces leakage. The upper connector is made of reinforced nylon fiber material, which is more impact- and abrasion-resistant than ABS or plastic. An inner rubber ring around the waterproof battery cover protects the internal battery.
