Elimination of Survey Markup.
OptiClino uses existing survey wall stations, which means:
- Less work for surveyors
- Drill doesn't wait for markups
- No rework for survey remarking or refreshing paint marks
OptiClino.
The most accurate longhole alignment system. No survey mark-ups.
OptiClino works entirely from existing surveyed wall stations, removing the survey mark-up bottleneck. Engineers send a drill design straight to the tablet — drillers begin immediately.
Elimination of Human Error.
Every operator is an expert:
- No lining up on paint marks — the driller is guided to sub-millimetre precision via a tablet.
- No possibility of setting up on the wrong hole or drilling the wrong angle.
- Can't cheat the system. All setups are recorded as-drilled.
- No need to articulate the rig onto laser lines; operators set up straight in the drive.
2× Accuracy over Fibre Optic Gyro and OEM Systems.
9,189 holes surveyed across 29 underground mines in Western Australia during 2025 showed the following average drill setup error over a 20 m hole:
- OEM1.46° · 509 mm at toe
- Fibre Optic Gyro1.33° · 469 mm at toe
- OptiClino0.58° · 202 mm at toe
