Apodemus Bat Lure

The BatLure is a digital acoustic lure, built to playback sounds of up to 100 KHz. Both time expansion and real time sound recordings can be used. Time expansion recordings are automatically recognized and played back in real time.
The robustly constructed device runs using an SD-card and 8 AA batteries.
 
The BatLure is suited for:
 
The luring of bats using recordings of social- and echolocation bat calls in order to catch them for research purposes;
To draw the attention of bats to a new potential roost to hasten its colonization. For example: bat boxes, newly constructed hibernacula as well as new summer- and maternity-roosts;
The playback of bat calls during training and bat-detector courses;
The testing of bat detectors and sound recording devices;
The localization of mating roosts through playback of male song/vocalizations and observation of responding territorial males.
 
The device is compact and robust, and is fitted with a tripod attachment mount. Sounds are played back from the supplied SD-card, which comes with several pre-loaded recordings*. Users can also load their own recordings onto the SD-card.
The BatLure is powered by an internal battery source (8 AA batteries), or via an (included) external cable (input 12V).
 
Optional extras include the external speaker, power kit, timer, solar kit and spinner.
