About this product

The D-100 is an entry-level heterodyne detector employing two different types of microphones for maximum sensitivity across a range of frequencies. The frequency controls are backlit for ease of use and a loudspeaker is built in. Headphones can also be attached. This rugged unit is small enough to fit in a pocket yet sensitive enough to start your bat detecting with accuracy.

Heterodyne bat detectors are great for beginners and offer immediate identification of bats in the field. You select the ultrasonic frequency range to listen to just like tuning in radio. Heterodyne detectors typically have a headphone socket and often have a line-out socket for recording calls. (Heterodyne recording are useful for listening to calls and learning the distinctive sounds of each species, but they are not suitable for further in depth analysis).
