Full Spectrum bat detectors allow you to record original frequencies in an unaltered state & the full frequency range. They record when triggered by sounds within a specified frequency & amplitude range.
With these devices, you get the best of both worlds. They offer the ability to record continuously in real-time as per Frequency Division devices, whilst providing high-level detail much like Time Expansion devices. Our active, hand-held range includes the Anabat Walkabout, Echo Meter Touch, & BATLOGGER M/M2.
