The Spar 300 utility surveying system from Vivax-Metrotech collects positions in site coordinates, in a package that easily adapts directly to a range pole, ATV, riverboat or pushcart. It continuously logs the utility depth and offset, along with statistical confidence and automatic offset calculations. Over a Bluetooth or USB link, the instrument outputs the 3-D positions to a Trimble TSC3 or tablet for real-time display on the Trimble Access map, independent of its own perspective with respect to the utility or the GNSS antenna. When a complex locate scenario is encountered, as can occur when several utilities are co-located within a common right-of-way, it applies automatic tolerance masks to the position data, flagging these areas on the map. 800/446-3392; www.vivax-metrotech.com.
