Echo Meter Touch 2 PRO Bat Detector Tutorial Videos
The Echo Meter Touch 2 (Standard and PRO) transforms your smartphone or tablet into a professional bat detection tool. Designed for researchers, environmental consultants, and wildlife enthusiasts, it provides high-fidelity recordings with noise reduction and enhanced bat call capture. Compatible with Android (USB-C or Micro-USB) and iOS devices, it works in the field without internet connection. Includes real-time listening modes, interactive spectrograms, geolocation, and automatic species suggestions via Bat Auto-ID technology.
Bat echolocation calls are ultrasonic and generally inaudible to humans. The Echo Meter Touch 2 combines a specialized microphone with advanced circuitry and software to convert these ultrasonic calls into audible sounds. Calls are displayed in a scientific-level interactive spectrogram. Users can pause audio, zoom in on recordings, and listen in one of three professional modes: Real-Time Expansion (RTE), heterodyne, and post-recording time expansion.
Both Standard and PRO models allow real-time bat monitoring, probable species identification, visualization of echolocation, recording location tracking on maps, and easy sharing of findings. The PRO version adds higher sensitivity, electronic noise reduction, and advanced recording options, while the Standard version delivers reliable professional performance for bat research and observation.
The SNR measures the volume of bats relative to background and electronic noise in a recording. A bat detector with high SNR is preferable, as it can capture faint or distant 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 record high-frequency bats (above 60 kHz).

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

Directionality indicates how many decibels (dB) are lost as a bat moves away from the microphone’s most sensitive area. EMT 2 PRO and EMT 2 detect bats broadly in front of you while minimizing echoes reflected off your body.

Note: Requires an iOS or Android device with a USB-C port. iOS devices with a Lightning port are not compatible (even with an adapter). Android devices with Micro-USB ports require an approved OTG adapter. Includes a USB-C extension adapter for use with phone and tablet cases. See the list of compatible devices and adapters below.

For users who need to send weather data far beyond the typical 1,000′ (300 m) wireless range, the Davis Wireless Long-Range Repeater extends transmission distances up to two miles (3.2 km). This makes it ideal for farms, industrial sites, research stations, and wide-area environmental monitoring.
This repeater requires two external antennas (sold separately). Each repeater includes a transmitting cable and a receiving cable, each terminating in connectors ready for an external antenna. You may choose between the omni-directional antenna (#7656), which covers 1,560′ (476 m) in all directions, or the Yagi directional antenna (#7660), which covers 5,000′ (1.5 km) in a single direction. Mix and match antenna types based on your collection and transmission needs.
The repeater features a solar-powered charging system designed to operate continuously even under low-light conditions. It includes a weather-resistant shelter, solar panel, regulator circuit, rechargeable battery, and mounting hardware for easy installation.

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.
