DS Series

DS Direct Aiming Station with XPointing Technology
Featuring Topcon's new XPointing technology, the DS seeks out prisms even in dim or dark conditions, fast! Tailor made for construction, the DS also features advanced TOPO, stakeout and mesh scan capabilities via it's onboard MAGNET™ software. And it's made to go right to work. In fact, the DS's ease of operation will be obvious from the time you turn it on. Simply add a data collector and the DS becomes a one-man measuring solution! The DS features a Bluetooth range of up to 1000' (300m), a waterproof housing, super-accurate encoder for reliable accuracy, and TS Shield to secure and maintain your investment. The DS is the construction layout tool you can't afford not to have.
