ZL190PLUS Land Surveying Equipment, Handheld GPS for Surveying with 3.2 Inch Color Screen, Multi-GNSS Support, 7 Measuring Models for Measuring Land Area, Length,Slope and Save Coordinates Points

**Large Display:** Boasts a sizable 3.2" sunlight-readable color screen with 240 x 320 pixel resolution for enhanced visibility even under bright sunlight. **Professional Precision:** Supports 6 satellite systems (GPS, Beidou, Galileo, GLONASS, NAVIC, and QZSS) for high-accuracy measurement. Area error is under 0.002 acres, and distance error is under 5 ft. **7 Measurement Modes:** Enables area measurement for irregular and regular plots like ranches and gardens; length measurement for straight and curved lines; height and slope measurement. It can also store the coordinate points of the current location (coordinates can be saved but not edited). **Durable with Extended Runtime:** Features an IP65 rating for excellent durability. Powered by a built-in 4000 mAh Li-ion rechargeable battery, offering up to 48 hours of continuous operation. **How to Use:** User-friendly interface with backlit buttons for straightforward and quick operation. The device must be kept level for taking measurements. It is advised to measure an area above 0.16 acres and a distance above 328 ft. Larger measurement ranges result in smaller errors. **Note:** Please search for satellite signals in an open, unobstructed area before use. When the signal value in the screen's upper left corner is below 1 m, you can begin using the device to ensure accuracy. This device is intended for surveying and is not suitable for navigation. The displayed altitude data is GPS altitude, which fluctuates with changes in received satellite signals; this is normal
