Buyer’s Guide: What to Consider

Choosing the right GPS for your tractor or trailer depends on your specific needs. Consider accuracy, autosteer capability, display quality, and compatibility to make the best choice.

• Accuracy Level: Consider the accuracy you need. RTK systems offer 2.5 cm, while PPP or CORS provide 1-10 cm. Basic guidance may suffice for less critical tasks.
• Autosteer vs. Guidance: Autosteer systems control the steering automatically, reducing driver fatigue. Guidance systems only show the path, requiring manual steering.
• Display Size and Durability: A larger, waterproof display is easier to read in sunlight and withstands field conditions. Look for at least 9 inches for clear visibility.
• Compatibility with Your Tractor: Ensure the system fits your tractor's mount and steering mechanism. Some systems are universal, while others may need specific adapters.
• Battery Life for Trackers: For asset tracking, battery life is crucial. Long-life batteries (up to 5 years) reduce maintenance and are ideal for unpowered equipment.

Conclusion

Selecting the best GPS for tractor trailers comes down to your primary use. For high-precision autosteer, the SMAJAYU JY305 Plus stands out. If you need simple field guidance, the MYACUC or LERTREE systems offer solid options.

For tracking trailers and equipment, the PIRITIZ GPS Tracker provides long battery life and easy installation. Evaluate your budget and accuracy requirements to find the perfect match for your farm or fleet.
