Helimag

Benefits

• High resolution magnetic data – recorded at 1200 readings/sec. (<5cm. sample interval)
• Increased data resolution due to helicopters ability to fly lower and slower than traditionally used fixed wing systems
• High accuracy positioning & navigation – suitable for DTM data
• Towed bird system – no aircraft effect on magnetic data (no real-time or post processed compensation required)
• Quick data transfer from the field back to head office – same day preliminary grids available
• Helicopters superior contouring capabilities – uniform data resolution
• Minimal ferry due to ability to base close to survey area
• Ideal for remote areas where no airstrips are available
• Digital video flight path available
• Aircraft equipped with satellite tracking for flight following
• Aircraft and support vehicle equipped with satellite phone and 2 way radio communications
• Experienced survey pilots and field crew
• Prompt system availability
