Ultra Compact, Highly Concealable – GT40
The GT40 is a high-performance GPS positioning terminal designed specifically for covert positioning scenarios. The device is equipped with 4G and 2G dual-mode networks, and its design is distinctive. The product measures 49*27*11mm and is wrapped in heat-shrink tubing. This allows it to adapt to various installation scenarios while achieving an extremely concealed appearance. This product is available with optional 150mAh or 300mAh batteries and operates in temperatures ranging from -40°C to 125°C. This makes it suitable for complex installation locations, such as outdoors and under vehicles.
High Protection
With IP68-rated water and dust resistance, the GT40 effectively isolates impurities and moisture from everyday dust intrusion, rain, and high-pressure water jets, ensuring stable operation of the device’s internal components, even when installed under vehicles or near outdoor equipment, where they are exposed to harsh environments. Its heat-shrink tubing design ensures excellent adaptability and concealment. The heat-shrink tubing adheres tightly to the device’s body, allowing for flexible adjustment to suit the installation scenario and seamless integration
Flexible Battery Life
The GT40 offers optional 150mAh or 300mAh external batteries, allowing users to choose the right one based on their positioning frequency and usage requirements. For short-distance, low-frequency positioning, the 150mAh battery is sufficient. For long-distance truck tracking, for example, the 300mAh battery effectively extends battery life, reducing the need for frequent charging and meeting the battery life requirements of different users
Strong Environmental Adaptability
It operates stably in temperatures ranging from -40°C to 125°C. Whether it’s the extremely low temperatures of winter in the north, the high temperatures of summer in the south, or the temperature fluctuations in industrial scenarios, the equipment can maintain normal positioning and data transmission functions, and will not experience problems such as freezing or shutdown due to extreme temperatures, ensuring reliable operation in various complex climates and environments

What are the advantages of GT40 smallest GPS tracker compare other trackers?
GT40 delivers the triple advantage of discreetness, real-time performance, and durability through three engineered innovations: heat-shrink tubing, ultra-wide temperature tolerance, and flexible battery options. Whether for automotive finance risk control, logistics cargo tracking, or outdoor asset monitoring, the GT40 targets the user’s core requirements with precision.
The heat-shrink tubing design enables a snug fit to vehicle wiring harnesses, blending seamlessly with original wiring for superior concealment. At just 49 × 27 × 11 mm, the ultra-compact form factor fits into hidden locations such as fuse boxes, seat frames, cargo gaps, or inside devices—offering concealment well beyond conventional magnetic-mounted trackers.
GT40 operates reliably across an ultra-wide temperature range (-40°C to 125°C). It withstands extreme cold and high-heat environments alike, including northern climates, engine compartments, and exposed outdoor equipment.
With IP68 full-scenario protection, GT40 meets top industrial standards for water and dust resistance, surviving immersion up to 1.5 m for 30 minutes. This provides robust operation in heavy rain, waterlogged vehicles, and dusty construction sites—exceeding typical IP67 trackers that only tolerate short-term submersion.
For specialized use, GT40 supports external batteries (150 mAh or 300 mAh) to tailor runtime. Smaller batteries save space for short-term positioning; larger batteries extend operation for long-haul freight and reduce charging intervals. This modular approach is more adaptable than bulky fixed-capacity wireless units and offers greater resilience to sudden power loss than conventional hard-wired trackers without backup.
