NX Control turns your iPhone or iPad into the display and control surface for GSSI NX-series ground penetrating radar systems. Requires a compatible NX-series unit — the app cannot collect data on its own. COLLECT - Live 2D radar profiles with distance and depth scales - Quick Scan for immediate single-line collection - Survey wheel or time-based triggering INTERPRET IN THE FIELD - Place target marks and read exact distance and depth - Calibrate depth by fitting a hyperbola to a known target - Tune gain automatically or by hand, with a live gain curve - Background removal, scan detail, and boost filters ORGANIZE - Group scans into projects and areas of interest - Attach photos to document what you found
