新DT101防伪多波束剖面声纳（即多波束回声测深仪）是一种单一的集成声纳工具，运动参考单元（MRU）和声音速度传感器为一体的圆滑和紧凑的单元。DT101只需要一根缆绳就可以操作三个换能器，对调查来说都是轻便的解决方案。与DT101 SIR（传感器接口继电器）电源/计时箱兼容，与双天线GNSS/GPS接收系统的简单连接可以进行水深地形测量。
The new DT101 anti-counterfeiting multi-beam profiling sonar (i.e. multi-beam echo sounder) is a single integrated sonar tool, motion reference unit (MRU) and sound velocity sensor in one sleek and compact unit. The DT101 requires only one cable to operate three transducers, making it a lightweight solution for investigations. Compatible with the DT101 SIR (Sensor Interface Relay) power supply/timing box, simple connection to a dual antenna GNSS/GPS receiver system enables bathymetric topographic surveys.
