ZL-180 USB Handheld GPS Land Area Meter — Backlit LCD, Automatic Trajectory & Slope Calculation, Manual and Vehicle Modes

Overview: Model ZL-180 is a USB-capable handheld GPS land area meter with a backlit LCD that shows trajectory, area and length in real time. Satellite accuracy: 0.8 m. Measurement error: 0.01. Length and width measurement: Yes. Automatic slope measurement: Yes. Real-time display graphics: Yes. Three real-time display options: real-time trajectory, real-time area, real-time length. Physical size: 140 * 58 * 22mm / 5.51 * 2.28 * 0.87in. Measurement modes supported: - Manual fixed-point measurement: Enter the manual fixed-point mode and press the "start" button to begin. Tap "start" once at each corner or inflection to add a fixed point. When you return to the beginning, press the "ok" key to have the device calculate and show the measurement results. - Vehicle mode measurement: Mount the unit on a vehicle such as a harvester, rotary machine, seeding machine, etc. Set the working width (cutting width) of the fuselage and the device will automatically record the travel track. Operating area is calculated as walking length × fuselage length. - Measurement of length and width mode: Supported for direct length/width inspection. How vehicle mode works: Place the meter on the machine, input the machine’s working/cutting width, then drive the working path — the ZL-180 logs the track and computes area from distance × set width. Package contents: 1 * Land Area Meter, 1 * Instructions, 1 * Hang Rope, 1 * USB Cable.
