vibration isolation
  • Highly accurate and relatively undisturbed core samples
  • Straighter holes with minimal deviation
  • Reduces waste by up to 80%
  • Faster than other overburden drilling methods
  • Greatly reduces the risk of project failure due to unknown or difficult subsurface conditions
  • Reduced noise levels
  1. ENHANCED SAFETY
    Interlocked rotation barrier - head rotation slows when open for enhanced safety.
  2. COMPACT FOOTPRINT
    Fits in shipping container and makes the LS250 MiniSonic perfect for smaller drill pads.
  3. ENHANCED SAFETY
    Rod presenter allows the casing to be loaded horizontally.
  4. EASY OPERATION AND MAINTENANCE
    Pilot operated hydraulic system is easy to operate and maintain.
  5. INCREASED PRECISION
    Eliminate time consuming rig moves with the articulated mast and wiggle tail which allows the mast to shift from left to right and front to back to position the mast precisely over the hole. The articulated mast allows for drilling from 90 to 45 degrees.
  6. HIGH EFFICIENCY ROTATION AND OSCILLATION UNIT
    Patented airbag system isolates the vibration from the rig and transfers it down the hole for more efficient drilling.
  7. INCREASED ACCESSIBILITY
    Wide track mounted and low ground pressure (.28 bar/4 psi) – perfect for increased accessibility in the most sensitive and fragile terrains.
