Product Name:RIEGL BDF-1
Product Description:The RIEGL BDF-1 is a laser range finder specifically designed for bathymetric surveying tasks. The compact and lightweight device is ideally suited for generating profiles of inland waterbodies when operated from a UAV. The topo-bathymetric depth finder comprises of tilt compensator, an IMU/GNSS unit with antenna, a control unit, and can be equipped with up to two external digital cameras.
