Using this information, the machine operator always knows the exact position, and work progress. This allows him to work exactly according to plan, precisely implementing the specifications. An additional LED display shows at first glance whether the target height has already been reached, or if needs to be raised, further. The work processes are accelerated, manual control measurements are no longer necessary and safety at the construction site is increased as no personnel need to be present, in the working area. Even during work under water, the excavator operator always maintains an overview with the Xsite® EASY. The system is ideally suited for use in foundation, trench or slope construction, leveling or underwater excavation.
