Pettersson D1000X: Considered by many (myself included!) to be The King of bat detectors.
Each D1000X from Pettersson Elektronik is built to order. For sheer ability, performance, and features - there's no other bat detector that comes close. Frequently selected by Professional Researchers, working on projects where accuracy is paramount.
What can I say about the Pettersson D1000X?
If you're looking for a hand-held recorder, the D1000X is possibly the 'holy grail' of bat detectors. However, with a price tag of £4100 and a heavy case, you may prefer the Elekon Batlogger M if you don't need a sonogram display; otherwise if you'd like a real-time sonogram display check out the Anabat Walkabout and the Wildlife Acoustics EM Touch.
All units record bat calls very efficiently, but the main consideration is going to be personal preference.
Personally, I'd choose the Batlogger M or M2 for a nice easy to use bit of kit.
With all of these units (except the EM Touch) you'll also get a free bat calls book worth £35: either British Bat Calls by Jon Russ, Social Calls of the Bats of Britain and Ireland by Neil Middleton et al, Bats of Britain & Europe by Christian Dietz & Andreas Kiefer, Is That a Bat? by Neil Middleton or a £35 voucher.

The D1000X is a professional ultrasound detector, based on the latest technology. The detector has heterodyne, frequency division and time expansion systems and also a built-in 16-bit recording system using a Compact Flash card as storage medium. It is equipped with our well-known, high-quality capacitance microphone which has been further improved to give lower noise, wider dynamic range and lower distortion.
Heterodyne, frequency division and time expansion systems. Uses a CF-card to store the signals as "wav" files. Recording and playback at sampling rates from 32 to 768 kHz. 16-bit Analog-to-Digital converter for increased dynamic range. Integrated, adaptive anti-aliasing filter. Manual or level-triggered modes – unattended recording possible. Accurate recording level indicator. Recording time limited by available CF-card space only. Adjustable LCD background and LED intensity. Battery and CF space indicators. Small size – 170 x 80 x 35 mm excl. microphone. Low weight – 600 g incl. batteries. Powered from internal batteries or external power supply, 7-10 V
The D1000X has a built-in "recorder", relieving the user from the hassle of operating a separate recording device or laptop with connecting cables. It can be configured to work in a variety of operating modes, but thanks to the use of "Profiles", switching between different modes is made instantly. Each profile contains all the selectable settings such as sampling rate, triggering mode, time expansion factor and LED intensity and can be prepared in advance and saved in the detector.
At any time, either the direct ultrasonic signal, the heterodyne signal or the frequency division signal can be recorded onto the CF-card. Spoken comments can be recorded by speaking into the microphone while recording in the direct mode, or in a special comment recording mode (at a lower sampling rate). The recording time is limited only by the available space on the CF-card. Upon completion of a recording in the direct mode, the signal will be automatically replayed in time expanded form, if this function is enabled. Time expansion factors from 1 (original speed) to 30 can be chosen. The recordings can be made by manually starting and stopping the recording or through level-activated (and optional frequency selective) triggering. In the latter case, the detector can be set up for unattended capture of calls. Pre- and post-triggering modes with a variety of different settings can be used.
The wav sound files on the CF-card are stamped with date and time and can be read directly on a PC, using a standard CF-card reader. The D1000X also has a serial GPS input, making it possible to save GPS position data in the files.

Hand-held recorders that can record full spectrum files and most of them log GPS co-ordinates.
Hand-held recorders that can record birds, frogs and other audible species. Some also record bats.
Comment from a client:
"My bat detector microphone failed during a dawn survey and knew that I had a group of dusk surveys starting in two days time. I was not in a good place as I did not have a spare, but my equipment was less than a year old.
After my survey I contacted Martin by email and he called me back on the same day, a few hours later, after a quick nap. He told me he did not have a part in stock, but had already contacted the supplier on my behalf.
The next day I received a replacement part, free of charge and express delivered from Switzerland. I thought it was amazing, and could not believe it was resolved so quickly.
Due to Martin's exceptional service I was good to go with the surveys, and I really would like to thank Martin and Wildlife Countryside Services for making the dusk surveys happen."
