The solar power means no battery changes ever - just toss it in your pool and it works season after season. Accurate within ±1°C from 0°C to 50°C, so you always know exactly when the water's perfect for swimming. Great for pools, hot tubs, fish tanks, ponds, fountains - anywhere you need to monitor water temperature. The green color makes it easy to spot, and the durable construction means it can handle being bumped around.
