      Using the Laser Rangefinder on the Max4T Drone

      Created: August 1, 2025

      Objective

      This SOP outlines the steps to effectively use the laser rangefinder on the Max4T drone for accurate measurements and real-time data sharing during operations.

      Key Steps

      1. Understanding the Laser Rangefinder

      • The built-in laser rangefinder enables precise distance measurement.

      • Useful for tracking objects during search & rescue, inspections, or tactical operations.

      2. Measuring Distance

      • Hover at approximately 270 feet for optimal line-of-sight measurements.

      • Ensure the camera is level to avoid miscalculation.

      3. Testing the Range

      • Aim the laser at a target and read the displayed distance.

      • Range varies with lighting and surface reflectivity (max ~3,900 feet).

      4. Saving a Measurement Point

      • Use the Pinpoint tool in the menu to mark a distance.

      • Confirm the save to log the location for later reference or mission planning.

      5. Navigating to Saved Points

      • Access saved points through the map interface.

      • The drone will fly to the selected point while maintaining camera tracking.

      6. Sharing Information with Teams

      • Mark points of interest and share their locations with ground or air teams.

      • Helps coordinate search zones or inspection targets.

      7. Using the Laser in Tripod Mode

      • In Tripod Mode, the drone maintains a static position while tracking moving targets.

      • The rangefinder updates the target's position in real-time—ideal for fast-changing scenes.

      8. Returning Home

      • Once the task is complete, initiate Return to Home for a safe landing.

      Cautionary Notes

      • Avoid using the laser in fog, heavy rain, or direct sunlight—these conditions reduce accuracy.

      • Make sure the laser has a clear line of sight to the target. Avoid foliage and glass obstructions.

      Tips for Efficiency

      • Confirm the camera angle before taking measurements. Even slight tilts can affect results.

      • Practice using the laser in various environments to become proficient in real-world scenarios.

      • Keep firmware updated to ensure optimal performance and measurement reliability.
