It arrives from Pettersson Elektronik, doubled-boxed. The unit (and included accessories) come in a neat, white box. Along with a ZipLok-type bag, as seen in Pic below:
The unit is intended to be used with a tablet PC (or equivalent) or a laptop computer.
I did a lot of testing of this unit on several types of devices; I preferred to use it with a laptop.
The newest version of this USB microphone, The M500-384 is very small and light - Yet, the M500 series is very strong at the same time (being constructed of sturdy Aluminum).
As per Pettersson's Site, the dimensions are: "43 x 114 x 13 mm (incl microphone horn)"
To be clear, both The M500 and The M500-384 are now the same physical size.
You'll also find this unit's additional features listed on the link above.
The instrument's very small size, allows it to be quite flexible, in terms of which devices it may be attached to.
It may even be used on devices as small as a cell phone. And anyone with prior experience with similar equipment, will find the unit easy to use.
I was excited about this new USB-based detector when it was first announced. I'll state, right from the start - that I really like the way it looked. I like the idea/design of the hardware itself - More specifically, the layout/design of the indicator lights (more on that later).
And as always, I'm interested in an ultrasound recorder which can be used for both unattended, and field recording of bats.
Of course, it may also be used to record other animals / ultrasounds as well. The other pleasant surprise, is it's price: Now you'll find substantial differences in price, depending on where in the World you're located, etc. But, I've seen prices from under $400 US Dollars -to- around £465 in the UK. So, it's not as expensive as some other solutions. As always, I advise you to shop around for the best price. Check-out:

An overview, of the very latest version of their Batsound Touch software, may be seen here.
The newly released, free version of the software has been designed to run The M500 smoothly, on almost all Windows tablets. And the M500-384, is even more flexible: It may be used on Windows an well as Linux platforms. And with different ultrasound recording software. The M500 is an ideal choice for someone who enjoys trying-out the various software packages available.
When considering the hardware which will be used with The M500: At the risk of stating the obvious, I would recommend using one with a high-power CPU, for best results.
The Batsound Touch software is very versatile, with lots of features; so there are quite a few ways in which to record sounds. More details to be added here, in the near future...
I've completed some tests and comparisons on one of the first prototypes of this unique microphone. Recording tests of The M500 revealed a very capable piece of equipment.
The M500 is lightweight and very compact. Upon plugging it in to my laptops (one running Windows 7, the other Windows 8) via USB cable, It was always recognized straight away.
I'm happy to report that The M500 can pick up bats at almost the same distances as my other top bat detectors. Some of which, have higher price tags than The M500.
And overall, it performed very well indeed! The sensitivity of this mic is wonderful!
The M500 is easy to hold and position, due to the durable & flexible USB cords that come provided.
Installation is easy, and it's easy to set-up and use: One end of the USB cable gets plugged into the M500 and the other end is plugged into your computing device.
The majority of (most commonly used) features, present themselves on your computer's screen, via The Batsound Touch interface.
The M500 (and M500-384) would be ideal units for those interested in:
Transects (esp. mobile/from a vehicle, or other forms of transport)
Unattended recording, as well as live recording (using a Netbook/small laptop PC).
When you are ready to record some bats -
- Plug one end of the (provided) USB cable into the back of the unit
- Plug the other end into an available USB port on your computing device
- Launch The Batsound Touch software
- Check the software's settings (which will be set the same as you left them)
- Click 'Record'
Even though, I realize that the the impact is minimal (to say the least). It seems to not only free up more PC resources (making the Batsound software scroll even faster), but also quiets background hiss even further. This may be a helpful "trick" to try, if you're using a low-end Netbook/laptop like mine.
For example, low-end notebooks will typically have suboptimal RF shielding.
So it appears that this is another case where the more I use this bat detector, the more I like it.
- Front-facing, high-quality sensor (microphone element)
- Simple device, robust: virtually nothing to break-off or get physically damaged.
- No batteries to worry about.
- Not weather-proof.
After a very straightforward software installation; using the device is simple:
- Customize the various recording Settings, as per your preference.
- Click the "Record" button, and you will observe the live spectrogram display and may adjust volume, etc.
It may be ordered directly from Pettersson Elektronik; here -or- by e-mailing: (email@example.com)

The simple fact is, this device can detect, and make useful (accurate) recordings of bats in flight - at impressive distances.
During my various tests, I also discovered that the recordings created by The M500 were of such high quality, that they enabled Auto ID software packages (such as Kaleidoscope) to produce more accurate identifications!
More accurate identifications, as compared to recordings from the other, high-end detectors.
The spectrograms produced are lovely. They will be added to this review, in the near future...
The M500 USB Microphone would be ideal for anyone performing passive (stationary) recordings of bats. It may also perform very well for driven transects; where the use of a laptop isn't a hindrance.
If the computing device used is very small, and light (cell phone) - I can see The M500 being a wonderful candidate for walking transects. It would be perfect for someone recording bats from inside a home. I've tested it in this way many times, using various laptops. It's very convenient to set-up. The Aluminum enclosure is secured outside, pointing in the general direction of expected bat activity.
You may even perform work on your laptop, while detection is in progress.
With The M500, we now have another, USB-based microphone for ultrasound recording; and it may be used across several devices. This review, is actually still a work-in-progress; and more Info and Pics will be added soon.
I'm happy to see, that there are quite a few USB-based bat recording solutions available to us now. Dodotronic has also released a new version of their Ultramic; which I am to be testing and reviewing soon.
Still to come, are reviews of The SM4BAT FS from Wildlife Acoustics, and The Batseeker 3.
Happy bat detecting!
