2373 Spectra Precision is introducing its sophisticated ProMark 700 system, a GNSS network RTK rover aimed at duties in land survey applications. The unit weighs in at only 650grammes and is said to be the lightest GNSS RTK smart antenna available on the market. Its light weight, together with its compact and slim design, makes the unit the receiver portable and comfortable for field use. It features a long battery life, a rugged, waterproof design and a wide operating temperature range, allowing the ProMark 700 to be used in harsh outdoor environments. The new receiver is equipped with 220 dual-frequency and dual-constellation GNSS channels that allow tracking of all available L1/L2 GPS/GLONASS satellite signals. It provides features for effective network RTK operations, without rarely-used modules or options. In addition, the ProMark 700 has been designed as an intuitive, simple and easy-to-use receiver, where all operations are performed from the data collector. Due to their size and light weight, the perfect companions to ProMark 700 are the low-cost MM10 data collector or the new T41 data collector with a smart phone design. The ProMark 700 receiver can be used with Spectra Precision field software: either Survey Pro v5.2.1 or FAST Survey v3.1. Both field software applications provide a complete set of features that meet the demanding expectations of professional surveyors and are optimised for RTK network surveys.
Sandvik DC125R is a new member to the proven Sandvik DC family of compact, rubber-tyred top hammer drill rigs. The fully remote-controlled, hydraulic and self-propelled mini-sized drilling unit on a four-wheel drive carrier, is for drilling 22–45mm holes, and replaces the former Sandvik DC122R, one in the series of rigs originally launched in 1988 under the product name of Tamrock Commando. “A range of job site tests show that the new model offers better manoeuvrability than ever before. This is thanks to t
Haulotte has added the HT21RT and HT23RTJ to its self-propelled boom line-up. The HT21RT has a working height of 20.6m, up to 15.9m of outreach. It is available in both two-and four-wheel drive versions.

Early detection of pavement defects and the causes of deterioration is essential for effective maintenance planning, writes Dr Alena Uus*
There is a need for optimisation and development of UK highway survey methods that would provide comprehensive information on the surface and subsurface pavement condition and operate at traffic speed, which eliminates the requirement for lane closures.
Performance of non-destructive testing (NDT) methods commonly employed in pavement condition surveys can be potent
