    \n
  • 60% improvement<\/strong> in data quality (reduced noise, fewer dropouts)<\/li>\n
  • 50% reduction<\/strong> in equipment failures<\/li>\n
  • 75% reduction<\/strong> in connector-related downtime<\/li>\n
  • \u20ac180,000 annual savings<\/strong> in maintenance and lost survey time<\/li>\n
