COMPACT, LOW COST SOLUTION

The wide 600 mm rubber tracks provide low ground pressure (.28 bar/4psi), perfect for jobs in the most sensitive and fragile terrains. The compact, smaller footprint makes it versatile for small drill pads, environmentally sensitive, or hard-to-reach sites.

ENHANCED SAFETY

The LS250 MiniSonic is CE compliant, featuring an interlocked rotation barrier which slows the head rotation when open for enhanced safety.

OPERATOR SAFETY AND COMFORT

The LS250 features a rod presenter where rod and casing can be loaded horizontally and an actuator then presents the rod and casing vertically to the head. The head rotates 28 degrees to the side for sample extraction. Head slide shift allows for unobstructed winch use down the hole.

COMPACT FOOTPRINT

Fits in a shipping container, making the LS250 MiniSonic perfect for small drill pads, environmentally sensitive areas, or hard to reach sites.

EASY OPERATION AND MAINTENANCE

Pilot operated hydraulic system is easy to operate and maintain.

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.
