Leica Geosystems introduced a new family of surveying total stations optimized for construction and building applications. The TPS110C has a keypad with six function keys. The high-end TPS410C features a high-resolution LCD with graphical user interface and on-board memory that eliminates the need for additional data loggers. Other features include standard camcorder batteries for full-day operation, endless drives and laser plummet. The TPS110C and TPS410C total stations incorporate electronic distance measuring technology, with standard infrared measuring to prisms and optional reflectorless measuring to 80 m with a visible red laser. The narrow bandwidth of the laser beam permits precise pointing to the target. The TCR110C reflectorless total station and all TPS410C models have a serial data interface for communicating with a PC or other devices.
