Follow Bryan as he covers the high points of the Batscanner bat detector. This device automatically displays the strongest frequency in the ultrasonic soundscape, making it simple to eavesdrop in on bats and get the first clue as to species. No knobs to break make it perfect for public bat talks or anytime you need quick assessment of the bat activity.
