Ankle Monitor - Refine Technologies: 108g GPS ankle monitor with 180-day battery life

Hey Product Hunt! 👋 I'm Kevin from REFINE Technology. We've been building GPS ankle monitors since 2004, and CO-EYE ONE represents a fundamental rethink of how these devices should work. The problem: Every GPS ankle monitor on the market runs GNSS + LTE 24/7, draining the battery in 24-72 hours. Officers managing 500+ monitored individuals spend 40% of their time dealing with low-battery alerts. Our approach: We added BLE and WiFi as communication layers. When the monitored person is home with their phone or near a WiFi repeater, the device switches to ultra-low power mode. Only fires up full LTE when actually needed. Result: 180-day battery in BLE mode. A $10 WiFi repeater eliminates cellular dead zones. Fiber-optic tamper detection means zero false alarms. Would love to hear your thoughts — especially from anyone working in corrections tech, IoT, or wearable devices. Happy to answer any technical questions!
