The Titley Chorus is a compact, weatherproof wildlife recorder designed for surveying bats, birds, frogs and other vocalising wildlife. Supplied with an acoustic microphone as standard, the Chorus is ready to use for bird and amphibian surveys straight out of the box, while its dual-channel design also allows the addition of an optional ultrasonic microphone for bat recording or a second acoustic microphone for stereo recordings.
Designed for reliable field deployment, the Chorus combines flexible scheduling, long battery life and built-in GPS functionality in a lightweight IP67-rated housing. Unlike many recorders, setup is completed directly on the device using the integrated OLED screen, with no need for Bluetooth or a mobile phone connection.
