Echo Meter Touch 2 PRO Bat Detector ²⁵

$ 451.20 USD

Turn Your Mobile Device into a Professional Bat Detector

Detect, listen to, and identify bats in real time with the Echo Meter Touch 2 PRO: professional precision in the palm of your hand.

Echo Meter Touch 2 PRO transforms your smartphone or tablet into an advanced acoustic bat detection tool. Designed specifically for researchers and environmental consultants, this device offers high-fidelity recordings with reduced noise and more captured bat calls. Compatible with Android (USB-C or Micro-USB) and featuring a free app, it's ideal for field monitoring without an internet connection. Includes real-time listening modes, interactive spectrogram, geolocation, and automatic species suggestions powered by Bat Auto-ID technology.

Signal-to-Noise Ratio (SNR)

SNR measures the loudness of bats relative to background and electronic noise in a given audio recording. A high-SNR bat detector is preferable as it allows for capturing quiet or distant echolocation calls. This chart compares the SNR of the EMT 2 PRO and EMT 2 at different frequencies. Since the EMT 2 PRO has a higher SNR, it is more likely to trigger and record high-frequency bats (above 60 kHz).

Sensitivity and Noise

This chart shows the microphone sensitivity and electronic noise produced by the EMT 2 PRO and EMT 2 across the recording bandwidth. The difference between 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. EMT 2 PRO and EMT 2 detect bats broadly in front of you while minimizing any echoes bouncing off your body.

Key Features:

• High-Fidelity Recordings: Low-noise microphone captures even weak or distant echolocation, reducing false positives.
• Real-Time Listening: Patented RTE technology preserves the tone and rhythm of ultrasonic calls.
• Species Suggestions: Automatic identification of the two most likely species, based on advanced acoustic analysis (region dependent).
• Free App: Available for iOS and Android. Includes live spectrogram, maps, recording, and customizable features.
• Mapping and Sharing: View recorded paths and instantly share files.

Analysis of the bat calls may be required in some situations e.g. in order to positively identify a certain species. The software BatSound is an efficient, high-performance tool for various types of sound analysis. It is suitable for sound analysis in general, but also includes a number of features particularly useful to analyze bat calls recorded from a bat detector or recorded directly with a D500X or D1000X ultrasound detector.

• Specifications
• In the Box
• Required Items
• Optional Items

• General Features
  - BatSound uses any Windows compatible sound card for sound input and output
  - BatSound supports sound formats up to 32 bits with one or two channels (mono/stereo) and sampling frequencies up to 192 kHz (possibly limited by the sound card). The common WAV format is used to store files. It is also possible to open sound files with other formats such as mp3 and wma if the corresponding codecs have been installed on the computer
  - Multiple windows with different sound files can be opened at the same time, facilitating comparison of signals and analysis results.
  - Printing and picture file export through Windows clipboard (BMP and WMF formats)
  - Wide range zoom function
  - Optional time and frequency compensation of time expanded signals to show the original time and frequency
  - Play Speed function to implement time expansion playback of high-speed sound files from D500X/D1000X detectors
  - Open Next/Previous command makes it easy to scan through all files in a folder. Very useful for browsing files obtained through unattended recording
  - Automatic parameter extraction feature, calculates max/min frequency, pulse duration etc
  - Optional grid lines in most diagrams
  - Clipboard export of analysis results
  - In the Virtual Bat Detector mode, sound files of time expanded or high speed recorded sounds are replayed at the original speed, emulating a heterodyne bat detector. Perfect for learning how to identify bats using a heterodyne detector, for classroom demonstrations etc
  - The Automatic Recording mode makes it possible to have the computer record sounds automatically. The desired threshold level is selected and the computer will start recording to a sound file as soon as the signal exceeds this level. Many parameters are available to fine-tune this mode, e.g. by setting limits for the minimum pulse length, total recording time, maximum number of pulses to record etc. Frequency-selective triggering is also available, to avoid recording undesired signals
  
  System Requirements
  - Intel or AMD 1 GHz or faster processor
  - RAM: 1 GB minimum (also depends on the operating system)
  - Windows compatible sound card
  - 1 GB or more of free hard disk space
  - BatSound version 4.1: Windows XP/SP3, Windows Vista/SP1 or Windows 7 operating system
  - BatSound version 4.2: Windows 7/SP2 or Windows 8 operating system
  
  Windows, Windows XP, Windows Vista, Windows 7 and Windows 8 are registered trademarks of Microsoft Corporation.
