Waterproof GPS pet tracker locator device with high sensitivity MTK2503D chip, polymer battery, and fence alarm alerts in black, sky blue, pink, or grass green, 65.5 x 37 x 18.3 mm compact design for cat dog collar attachment
Waterproof GPS Pet Tracker and Locator with Fence Alarm for Cats and Dogs

Keep your pet safe with this compact, intelligent GPS tracker designed for reliable outdoor monitoring. This device utilises a combination of GPRS, Beidou satellite, and LBS (Location-Based Service) networks to provide accurate location data, whether in urban areas or more remote settings. Its core functionality includes a configurable fence alarm, alerting you via connected app if your pet leaves a predefined safe zone. Encased in a waterproof ABS and PVC housing, the tracker is built to withstand the elements and attaches discreetly to your pet's collar. With multiple operational modes balancing battery life and update frequency, it offers a practical solution for concerned pet owners.
Technical Specifications and Performance

The tracker's performance is defined by its chipset, connectivity, and environmental tolerances, providing a reliable tool for pet location.
Positioning Technology and Accuracy
At its core is the MTK2503D chipset, which manages connectivity across GPRS, Beidou, and LBS networks. This triple-system approach ensures a location signal is available in varied environments. The GPS positioning offers an accuracy of 5 to 15 metres under clear sky conditions, suitable for identifying a general area. For scenarios where GPS signal is weak, such as dense urban canyons, the LBS (cell tower) positioning activates with a broader accuracy range of 100 to 1000 metres, providing a useful fallback to maintain a general location fix.
Battery and Operational Modes
Power is supplied by a built-in 500mAh polymer lithium battery. Its performance is directly linked to the chosen tracking mode. The 'Default Mode' uploads location data once per hour, prioritising battery conservation and offering a standby time of 4 to 5 days on a single charge. For more intensive, real-time tracking, the 'Standard Mode' increases the upload frequency to once every 30 seconds, which reduces the standby time to between 12 and 15 hours. This allows owners to choose between longevity and frequent updates based on their immediate needs.
Durability and Environmental Limits
The device is designed for active outdoor use. Its housing is constructed from ABS plastic and PVC, materials chosen for their impact resistance and waterproof properties. This construction allows the tracker to be worn in rain or during your pet's aquatic adventures. It is rated to operate effectively within a wide temperature range, from -20°C to +55°C, ensuring functionality during winter walks and summer outings alike. The compact form factor, measuring 65.5 x 37 x 18.3 mm, keeps it lightweight and unobtrusive on a collar.
Key Features and Practical Use

Beyond its technical specs, the tracker includes user-focused features that translate data into actionable insights and peace of mind.
Geo-Fence and Alert System
A central feature is the configurable geo-fence, or 'fence alarm'. Through a companion smartphone app or web portal, you can draw a virtual boundary on a map, designating a safe area for your pet. If the device's location data indicates your pet has crossed this boundary, the system triggers an immediate alert to your phone. This proactive notification allows for a swift response, whether calling your pet back or initiating a search, rather than discovering their absence much later.
Device Setup and Attachment
Setting up the tracker involves charging the battery, activating the SIM card (if required by the network), and pairing the device with its dedicated application. The unit itself is a single, integrated device with no loose parts beyond its attachment point. It is designed to be secured firmly to your pet's existing collar via a loop, clasp, or a dedicated pouch (sold separately unless included). Its small size and weight minimise discomfort for the pet, making it suitable for both cats and medium-to-large dog breeds.
Colour Options and Visibility
The tracker is available in four distinct colour variants: Black, Sky Blue, Pink, and Grass Green. This choice allows you to select a colour that either matches your pet's gear or provides a contrasting, visible marker on their collar. The specific two-tone 'Black on the outside and yellow on the inside' variant mentioned offers high visibility, which can be an additional safety feature during low-light searches.
Value and Considerations for Buyers

Understanding the tracker's place in your pet care routine helps assess its practical value and limitations.
Addressing the Core Concern of Loss
This product directly addresses the anxiety and risk associated with a lost pet. By providing a real-time or frequently updated location, it significantly reduces search time and area, increasing the chances of a quick and safe recovery. The fence alarm adds a preventive layer, notifying you the moment your pet strays, which is invaluable for pets with a tendency to wander or escape from gardens.
Network and Subscription Considerations
It is important to note that the GPRS functionality, which transmits the location data to your phone, requires an active mobile data SIM card with a suitable service plan. Buyers must source and activate a SIM card (typically a micro or nano SIM) and ensure it has adequate coverage and data allowance in their area. The cost and management of this ongoing subscription are separate from the device purchase and are a key part of the total cost of ownership.
Realistic Performance Expectations
While the technology is robust, performance can be affected by environmental factors. GPS accuracy is best outdoors with a clear view of the sky; it will be less precise indoors or under heavy tree cover, where LBS may take over. Battery life is a trade-off with update frequency. For everyday monitoring, the default mode offers a good balance. For specific high-risk situations or training, the standard mode provides near-real-time tracking at the expense of daily charging. The device is a tool to aid recovery, not a substitute for secure fencing and responsible supervision.
