Product feature: Digga NZ's HALO system

Digga NZ says their HALO system is the next step in achieving plumb straight foundation holes

The clever alignment system is located in the hood ring of the auger drive and provides the machine operator with a simultaneous clear line of sight to itself as well as the hole being dug. 

HALO utilises a band of LED lights, which, when fully illuminated green, signals to the operator that the drive is plumb. If the drive does happen to move from its plumb position, a sequence of red and green lights will be lit allowing the operator to guide the drill back to the correct upright position.

The recessed dust/waterproof LED ring features high-accuracy inclination green and red LED indicators, which can be clearly seen in daylight; there’s no need for an in-cab display screen and no need for the operator to take their eyes off the job to realign the auger and effectively eliminates the need for a spotter with a spirit level

The HALO system utilises a microprocessor and six sensors to provide accurate readings to +/- 0.25 degrees even under heavy vibration say its manufacturers.


Features include

  • No need for a spotter and spirit level to guide the operator
  • Allows the operator to never take their eyes off the job        
  • Ensure holes are drilled plumb and reduce the number of in-hole angle adjustments
  • No oversized holes—reduce the amount of concrete required to fill the hole
  • Eliminates sideload on auger drives and augers, reducing equipment damage
  • Get back to drilling faster after returning the auger to the hole
  • Significantly less than traditional systems and eliminates the need for a costly in-cab display
  • Highly visible indicator
  • Made in Australia by Digga Australia
  • Four years of development and testing

No set-up (battery option)

HALO can be connected to the in-cab cigarette lighter or powered by a magnetised rechargeable battery, which will last all day and can be charged via USB or a 240-volt wall charger. The battery pack can be attached to the drive hood, frame, machine boom, or placed in-cab.

The battery-powered option also features a ‘zeroing’ function, which lets the operator set the angle of inclination with the press of a button. This feature is ideal for the installation of shade sails.

HALO is currently available for Digga PD3–PD7 auger drives, with a complete range to be introduced in the near future.
