Built to handle splashes and weather, this device aims to deliver consistent visibility from dawn until late at night. The result is a low-maintenance companion that invites you to enjoy more time by the water, rather than chasing readings.

Long-range clarity and vivid display

• 650FT Wireless Transmission delivers real-time data from the pool to the indoor receiver across typical home layouts.
• Extra-large, backlit screen remains easy to read in day light or after dark thanks to an intelligent light sensor.

Power and convenience

• Solar-powered charging with a large solar panel offers higher energy conversion, helping the unit stay ready with minimal maintenance.
• No battery replacements required for the floating unit, so you can spend more time swimming and relaxing.
• Rechargeable indoor receiver uses a Type-C port; two hours of charging can support up to about two weeks of use, plus it doubles as a room environment monitor showing temperature, humidity, and time.

Precision meets practicality

The device uses a high-precision sensor and reports temperatures in a wide range, adapting to daily swimmers, hot tubs, spa sessions, or ice bath routines. Updates occur every second, helping you track shifts in water conditions with confidence.

In real life, you might rely on it to gauge morning pool readiness before a jog, plan a spa session after a busy day, or coordinate family swims with friends. The combination of long-range transmission, a readable display, and low-maintenance charging makes routine monitoring feel effortless. While outcomes depend on your environment, the system is designed to offer practical visibility and dependable data without heavy upkeep.
