Heterodyne Bat Detectors
CDB105 Mono
CDB105 Mono
This is the smallest and cheapest detector of the heterodyne series from Ciel Electronique. It is ideal as a starter unit or for use by young observers. The CDB 105 is a heterodyne detector, and to assist in dialing the observing frequency there is a scale printed on the panel. The unit uses electret microphones as their wide range, from 15 kHz up to 120kHz, make them perfect for listening to different species of bat. The unit is designed with de-centered knobs so that it can be used in one hand, almost as easily as with both hands, even by a child. The unit comes with an integrated speaker for group listening, or can also be used with the included lightweight headphones, which can be connected via a 3,5 mm jack. It also has an integrated LED torch, to help whilst walking through dark woods. Requires a 9v battery which is not included with the device.
Please note, we will try to supply your choice of colour, but it is dependant on stock.

CDB301 Advanced Dual Detector R3
CDB301 Advanced Dual Detector R3
The CDB301 was the first unit in the CDB series to combine both a heterodyne detector with a frequency division detector. It has recently been updated with the revision 3 of this best selling unit. Each function has a separate microphone to gain the highest sensitivity. In HD-mode, you can tune the observed frequency, which is shown on a 2x8 digit backlit LCD-display, helping you to identify the bat by sound and frequency. In FD-mode (including amplitude recovery), you observe the whole band at once, and so can easily identify if there are bats around. It has the additional option of switching channels to left/right, enabling you to observe the full frequency in FD-mode on the left channel, whilst tuning the right channel in HD-mode. The R3 now includes an integrated commentary button, enabling you to take notes. The headphones are connected via a 3,5 mm jack, and are included with the detector. Requires a 9v battery which is not included with the device.
