Void Scanner Mk3

A ruggedised, underground, 3D laser scanner used for routine 3D mapping of inaccessible stopes, voids and tunnels. The Void Scanner Mk3 has a 150 meter range and can be deployed on a boom, tripod, Boretrak® rods or customised mount. These flexible deployments allow the collection of precisely referenced point clouds in complete safety. The new Mk3 model has an improved drive system and faster scan speed which significantly reduces survey times, saves costs, and improves safety for the operators.

The Void Scanner Mk3 is small, rugged, lightweight, and designed specifically for harsh underground environments.

Simple to use, the Mk3 scans 200 points per second and stores the data on a rugged tablet, PC or laptop computer.

The Void Scanner Mk3 comes complete with MDL's Voidscan software which is used to control the unit and to display (in real-time) laser point clouds in 3D. Data may then be exported into any mine planning package.
