Heterodyne

Heterodyne detectors are by far the most affordable & easy-to-use. They are designed to be tuned to a frequency range of your choice. Calls are then converted into audible sounds that you can listen to! They are perfect for beginners. Brands on offer include Pettersson, Batbox, Elekon & Magenta.

For those looking for alternative hand-held bat detectors, check out our Time Expansion and Full Spectrum pages.

If you are looking for something that can record sounds for post-visit analysis why not take a look at the Frequency Division range. Some models have dual modes & also have Heterodyne functionality.
