Profile: Measurement Devices Ltd (MDL) specializes in the design, manufacture & service of laser measurement technology and positioning & navigation systems. The LaserAce® 3D was designed to help foresters easily measure the height, diameter (at any height), lean, log volumes. With the addition of the internal digital compass, foresters can now quickly measure a canopy spread or clearance distances between trees and buildings. Cabled Boretrak® is a borehole deviation surveying system, that has been designed to be compact, lightweight and highly portable. The system features a rugged probe containing a dual axis tilt sensor and digital compass that calculates the borehole deviation from the collar position at fixed intervals. Data is transmitted to the surface via the heavy duty cable and recorded in the MDL CDU logger. The CDU can be handheld or attached to the MDL lightweight tripod for ease of use. The Boretrak® borehole deviation system is also supplied with a weighted extension piece that can be filled with lead shot or sand, to ballast the system for use in deep or flooded holes. Boretrak® 3D software is used to process the data and produce a hard copy of the results. Holes can be displayed individually, or in any combination to determine hole separations. The data can also be integrated into 3rd party software systems.
