Description
With digital noise reduction that removes intermittent sounds like dogs barking and passing vehicles. DNR-18, the advanced digital CPU eliminates intermittent interfering noises, like passing vehicles, people talking, and pedestrian footsteps. Traditional band pass filters filter continuous noises, such as AC hum, idling motors, and wind. While traditional filters are very useful, they are not able to filter out the common intermittent noises with broad frequency ranges.The DNR-18 has optional accessories for water leak pinpointing and water leak surveying.
