The Chorus from Titley Scientific is an easy-to-use recorder, compact, lightweight and adaptable. It comes standard with an acoustic microphone but can be expanded with an additional acoustic microphone for stereo recordings or an ultrasonic microphone. As a result, both acoustic and ultrasonic recordings can be made, so you can now record bats, birds, frogs and other vocalizing wildlife with one detector!
The Chorus is designed to survive the harsh field conditions. It's weatherproof and rugged, with unobtrusive microphones (to reduce the chance of wildlife chewing on it). But even if your microphones get damaged, they can be replaced by the user in seconds. So you do not have to send the detector back, but immediately replace the microphone in the field.
An acoustic microphone is included with the Chorus, so if you want to record birds or frogs, it's ready to go! It's also a dual-channel recorder, so you can add a second acoustic microphone for stereo recordings in addition to the ultrasonic microphone. These can of course be ordered separately at Veldshop.nl. You don't need any additional devices (such as phones) to set up the detector - no Bluetooth required, making detector setup more reliable. Check your configuration directly in the detector using the internal OLED display. You can choose from the automatic schedules for night mode, day mode or continuous recording. You can also create your own schedule; for example, you can record bats at night and birds during the day using the different microphones. You can even include bats in zero crossing on the detector to save memory space during long periods of use.
The battery life of the Chorus is unparalleled, providing you with 300 hours of acoustic recording on just 4 AA batteries. (or recording up to 40 nights in the full ultrasonic spectrum, if you have purchased a separate microphone) Like all Titley detectors, the Chorus has a built-in GPS as standard. All your files are geotagged, your location is used to calculate sunset and sunrise for automatic scheduling, and you can even activate transect mode to record a track.
