Wildlife Acoustics ECHO METER TOUCH 2 (USB-C)

Product detailed description

Bat Detector with USB-C for iOS® and Android™. Turn your smartphone or tablet into an interactive bat detector. Flying at night and generally vocalizing outside the range of human hearing, bats can be difficult to detect. But with the Echo Meter Touch 2, you can hear, identify, and record nearby bats. Simply plug into your mobile device and install the free companion app to get started, no data plan required. A powerful tool for environmental educators and science coordinators looking to engage people of all ages in science. Also great for nature enthusiasts who want to learn about bats and their ecosystems.

Hear Ultrasonic Bat Calls
Discover and demystify a world unheard. Bats produce sounds outside the range of human hearing. Echo Meter Touch 2 uses sophisticated hardware and software to make bat vocalizations audible. Patented Real-Time Expansion (RTE) technology makes it possible to hear bats as they fly by.

Get Species Suggestions
Receive suggestions for the two most likely species of bat vocalizing nearby, thanks to Bat Auto-ID. This powerful feature leverages technology used in our Kaleidoscope Pro Sound Analysis Software to perform on-the-spot analysis. Get species illustrations, descriptions, and more. Classifiers currently available for North America, Europe, South Africa, and the Neotropics.

Technical specifications: 

Signal-to-Noise Ratio (SNR)

SNR is a measure of the loudness of bats vs. noise (background and electronic) in a given audio recording. Having a bat recorder with a high SNR is preferable, as it allows you to capture the vocalizations of quiet or distant bats. This chart compares the SNR of the EMT 2 PRO and the EMT 2 at different frequencies. While there’s little difference when recording bats that vocalize at frequencies under 60 kHz, the EMT 2 PRO is more likely to trigger and record high-frequency bats because of the higher SNR.

Sensitivity & Noise

This chart shows both the microphone sensitivity and the electronic noise produced by the EMT 2 PRO and the EMT 2 across the recording bandwidth. The difference of the two values determines the signal-to-noise ratio (SNR).

Directionality

Directionality indicates how many decibels (dB) are lost as a bat moves farther away from the most sensitive part of a microphone. Both the EMT 2 PRO and EMT 2 are designed to detect bats broadly in front of you while minimizing any echoes bouncing off your body.
