Superior Recording Quality


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.

Kaleidoscope Pro Auto-ID Classifiers


The Echo Meter Touch App includes the same species classifiers offered in the desktop version of the Kaleidoscope Pro analysis software. We continually improve existing and add new classifiers to the already long list of bats species in North America, the Neotropics, U.K. and Europe, and South Africa.


  • Listen to bat vocalizations in real-time and record calls with the free app
  • Utilizes Kaleidoscope Pro classifiers to suggest species and accelerate bat call analysis*
  • Shows recording locations and path on a zoomable map
  • Real time spectrogram shows more info than just listening
  • Quality recordings and advanced features at a fraction of the cost of competitors
  • Advanced settings allow you to fine tune trigger settings and adjust gain and sample rate
