Echo Meter Touch 2 Pro bat detector for Android or iOS - HIRE

Echo Meter Touch 2 Pro bat detector for Android or iOS - HIRE

For Hire. Adjust Quantity for the number of weeks you want it.

If you need more than one recorder, or a different model, please email us with your requirements.


A fantastic bat detector to plug into your phone or tablet to enable you to see sonograms of the bat calls and record them for future analysis.

This model is for Android or iOS devices with USB-C connector and is a Pro model - the Pro has a much better microphone and cleaner sonograms.

If you have an Android device with a MicroUSB connector, you'll need the USB-C to MicroUSB adaptor which is included.

We don't currently have a USB-C extender for use with a case on your Android device, sorry.


Flying at night, using ultrasonic vocalizations — bats can be hard for people to detect. But with the sophisticated technology inside the Echo Meter Touch 2 Pro, you can turn your smartphone or tablet into a professional-quality, interactive bat detector, allowing you to hear and record bats flying above you in real-time!


Learn about bats

There are thousands of bat species in the world, each with its own slightly different type of echolocation call. Every time you watch for a bat, Echo Meter Touch listens for it and processes the sound using highly complex, proprietary algorithms called “classifiers”. In a split second, Echo Meter Touch shows you the most likely species of bat flying overhead. You can click on each species to learn more. Currently, Echo Meter Touch can identify bat species from North America, the Neotropics, the U.K., Europe and South Africa.


Discover the world of ultrasonic sound.

Bat echolocation calls are ultrasonic – out of the range of human hearing. The Echo Meter Touch combines a special microphone with sophisticated circuitry and software to transform ultrasonic bats calls into audio that you can hear. Echo Meter Touch displays the bat calls on an interactive, scientific-level spectrogram. You can pause the audio, zoom in on each recording, and listen to it in more detail using one of three professional-level listening modes: Real-Time Expansion, heterodyne, and post-recording time expansion.

    Echo Meter Touch 2 PRO is an innovative combination of hardware and software that lets you listen to, record and identify bats in real-time – on your Android or iOS device.

    The Echo Meter Touch 2 PRO Ultrasonic Module creates extremely quiet, high-quality recordings which are superior to those created by bat detectors costing much more.

    Bat calls enter the Module through an integrated acoustical horn, engineered to reduce unwanted echoes. The horn efficiently directs the sound into the Module’s ultra-quiet microphone element (the same used in the SMM-U2 ultrasonic microphone) which captures frequencies of up to 192kHz. The Module’s onboard computer converts the sound into digital data and streams it to the Echo Meter Touch app.

    The app features a number of advanced software features designed specifically for professsional biologists: Choose a sample rate of 256kHz or 384kHz. Control recording amplitude by selecting one of three gain settings. Set specific trigger length, trigger window, trigger sensitivity and auto-trigger time. You can also choose audio division ratio for RTE, heterodyne, and time-expansion listening modes. You can even enable/disable Nightly Sessions Mode and Real-Time ID.

    The Echo Meter Touch app transforms the Module’s streaming data into audio that you can hear – in real-time. It shows you the bat calls on an interactive spectrogram, and it employs the latest Kaleidoscope Pro classifiers that instantly identify the most likely species of bat being detected. It uses GPS to mark recordings with your location and path and, of course, it saves the recordings as 16-bit WAV files that can be easily shared for collaboration or transferred to a Mac or PC for further study.

    The Echo Meter Touch App includes the same species classifiers offered in the desktop version of the Kaleidoscope Pro analysis software, covering bat species in North America, the Neotropics, U.K. and Europe, and South Africa.

    There’s no other professional bat research tool that offers this combination of portability, high-quality recording, species identification, and high-detail spectrogram analysis capabilities.

  • Requirements


    • Android OS version 8.0 or later.
    • An OS version later than 8.0 is not a guarantee that the device is compatible, see the list below.
    • The Echo Meter Touch app will not load on devices running any version of Android Go.
    • At least 1 GB of total RAM.
    • At least 600 MB of storage for buffering the spectrogram.
    • OTG compatibility. There are many free apps that can check such as OTG?.
    • A USB-C connector, or a USB-C to MicroUSB adaptor if your device has a MicroUSB connector.

    Compatible iOS Devices:
        •    iPhone: All models with USB-C port
        •    iPad: All models with USB-C port


    • See the “Compatible Phones” and “Compatible Tablets” sections below for Android devices known to work with the EMT2. This list is compiled from the results of an in-app survey that ask about device compatibility. If a device is not listed, that does not mean it does not work; it only means that we have not had any reports in the survey.
    • While we cannot guarantee compatibility with the list below, we do offer a thirty-day money-back guarantee.
    • As devices become older, they may have increased difficulty running EMT2 with newer versions of the app or OS updates, so we reserve the right to remove devices from the list.
    • EMT2 will work with a USB-C or a micro-USB port on your Android device. EMT2 modules made before May 2022 have a micro-USB plug and modules made after have a USB-C plug. Either type of module can work on either type of Android device, but you will need to use an adapter if they do not match. EMT2 will only work with iOS devices with USB-C connector.

    Please email us with details of your device so we can check if it's on the compatibility list, or check the Wildlife Acoustics website.

  • Classifiers

    Currently, we have bat species classifiers for North America, the Neotropics, the U.K. and Europe and South Africa. We're continually developing new classifiers as well as improving existing ones.

    Note: Classifiers in the Echo Meter Touch app may lag the Kaleidoscope classifiers by several weeks. Watch for updates to the app to get the latest classifiers.
