The best device yet for leading a bat walk - and it's free! And the companion microphone can be built for the ridiculous low price of £10!!
Bat Detector is a free iPhone app that, when used with a 384kHz USB microphone, turns your device into a heterodyne / time-expanding detector and full-spectrum recorder. Its 5 second, 384kHz recordings are perfect for uploading to the BTO Acoustic Pipeline, and recordings are geolocated using GUANO metadata.

Specifications
Bat Detector requires an iPhone, iPad or iPod Touch running iOS 15 or later. It also requires a 384kHz class-compliant USB microphone.
Bat Detector shows on screen the recent history of sounds heard by the attached microphone in the form of a scrolling sonogram. An optional "Elastic" view compresses time non-linearly, giving a zoomed-in view of very recent activity, and a compressed view of events more than a few seconds ago. The most recently-detected bat call is shown in detail at the top right of the screen, and if time expansion is selected that call is replayed at 1/16th real-time (4 octaves below actual bat pitch).
The official Bat Detector USB microphone is available as a self-build project from PCBWay (build cost approx. $17 including 3D printed mount) - here for the "normal" mic and here for the special edition "Griff the Superstar Noctule" version.
The π•pistrelle and pippyg bat detectors can be reflashed to operate as 384kHz USB microphones to use with Bat Detector.
AudioMoth USB microphones are also known to work with Bat Detector.
