Sentinel Pebble – Rugged Multi-Purpose BLE Tracker + Platform Access

The Sentinel Pebble is a compact, heavy-duty BLE tracking device engineered for industrial, outdoor, and high-impact applications. Built within a rugged IP68-rated enclosure, the Pebble is designed to withstand moisture, dust, vibration, and physical shock, making it ideal for tools, equipment, mobile assets, and operational environments where durability is critical. 
 
Powered by a high-capacity 800 mAh CR14250 non-rechargeable disposable battery, the Pebble delivers up to 36 months of uninterrupted operation with zero charging required. Throughout this period, the device connects via the global BLE crowdsourced detection method, enabling proximity-based visibility, movement insights, and last-seen location updates without relying on GPS, SIM cards, Wi-Fi, or cellular connectivity.
 
An integrated 80 dB buzzer supports rapid on-site recovery, helping users find assets in warehouses, workshops, construction sites, storage facilities, or dense operational environments. 
 
Platform access is included for 36-months. During this time, users benefit from proactive fleet and asset oversight, including geofence alerts, movement notifications, BLE detection logs, event history, and device-health monitoring. Unlike reactive consumer tools such as Apple “Find My” or Google “Find My Device,” which provide only last-known location after loss, the Sentinel Platform offers pro-active monitoring and real-time alerting to prevent loss before it occurs. 
 
After the original battery lifespan ends, users can replace the battery and maintain uninterrupted platform access by subscribing to a monthly Platform Access Plan at R10 per month, enabling continued digital oversight. 
 
Compact, durable, and low-maintenance, the Sentinel Pebble is a dependable BLE proximity-tracking solution for operational environments requiring long-life performance and robust physical resilience.
