Our 3-element foldable Yagi antennas are designed to enhance signal reception and transmission within a specific directional range. Unlike omnidirectional antennas, these models offer greater directional gain, focused signal tracking, and reduced interference, significantly improving tracking performance in the field. They can be custom-tuned to operate within the 148 to 225 kHz frequency range, depending on the transmitters being used.

The Telonics TVR-1 Test Receiver is a portable, compact receiver designed to detect VHF transmitter signals in the 145–170 MHz range. This device is ideal for quickly verifying whether a transmitter is on and functioning, both in the field and in the lab. It provides both a visual and audio indication for each received transmission, along with a pulse output that can be connected to recorders or data acquisition systems. It operates on a standard 9V alkaline battery and is specifically designed for short distances of 2 to 3 feet.

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.
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).
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 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.

El análisis de las llamadas de los murciélagos puede ser necesario en algunas situaciones, por ejemplo, para identificar positivamente una determinada especie. El software BatSound es una herramienta eficiente y de alto rendimiento para varios tipos de análisis de sonido. Es adecuado para el análisis de sonido en general, pero también incluye una serie de características particularmente útiles para analizar llamadas de murciélagos grabadas desde un detector de murciélagos o grabadas directamente con un detector de ultrasonido D500X o D1000X.
