Love it, but wish it came in more colors
I always know where my keys are now, and the alerts are reliable. The only reason I gave 4 stars is I wish it had more color options — otherwise, perfect.

Features
Using SENTRA
TRACKING YOUR ASSESTS
Designed for the rigors of commercial use and personal protection, the SENTRA ONE Tracker features a built-in battery engineered to last up to 3 years. No recharging, no cables, no interruptions — just set it and forget it.
Whether you're safeguarding a newly purchased classic car, monitoring expensive tools, or simply wanting complete visibility over your personal belongings, the SENTRA ONE Tracker is the simple, powerful, and secure choice.
Attaching your tracker
Place the tracker against a flat, metal surface on your asset. Align the magnetic face directly to the surface and press firmly until you feel it sit securely into place. Ensure the device is flush against the surface for maximum hold and discreet placement.
Powering on & customizing
Power: The Sentra One Tracker comes pre-fitted with a CR2477 coin battery — no setup or charging required. Simply download the app and it's ready to go straight out of the box.
Battery: With up to 3 years of standby life, the long-lasting CR2477 battery means your tracker works quietly in the background for years at a time. When replacement is eventually needed, coin batteries are inexpensive and widely available.
Tracking: Download the supported app on iOS or Android to view real-time location updates, manage your devices, and keep tabs on your valuables — all from one intuitive interface.
Tracking in ActiON
Once set up, the Sentra One Tracker works silently in the background around the clock. Attach it magnetically to any asset — a vehicle, tool kit, or bag — and monitor its real-time location directly from the CitiTag app. Whether you're at home or on the other side of the world, you'll always know exactly where your valuables are.
Safety Precautions
Do not attempt to open or tamper with the device, as this may damage the internal components and void your warranty.
Keep the device away from extreme heat or prolonged direct sunlight, as this may affect battery performance.
Ensure the magnetic attachment is secure before use to prevent loss or damage to the tracker.
