Files updated 5th Octoberl 2025 to update the silk screen to match the parts list.

Files updated 18th April 2025 to replace the microhone chip which was obsoleted by the manufacturer.

A very small, very powerful handheld bat detector with heterodyne and time expanded output, frequency feedback provided by speech synthesis. And this one HAS AN OFF SWITCH!

The microphone solder stencil has been updated to more closely match the manufacturer's recommendation - this may result in a hole too small to be cleared out with the diode tool, let me know if it's a problem.
