This album was recorded using an ultra-sound BatBox Duet in London in 2007/8.

The Batbox Duet is a dual-mode bat detector, with both heterodyne and frequency division, which has been designed for single-handed operation. The large LCD back-lit display is extremely accurate and easy to read at all light levels. Frequency amplitude detection allows post-recording computer analysis of sonar peak-frequencies. There is a voice commentary button for annotating recordings.
