Hi there,

What can I say about the Wildlife Acoustics SM4BAT FS?

If you're looking for a static full spectrum recorder to leave out on site, the Wildlife Acoustics SM3BAT and SM4BAT FS, the Anabat Swift, the Pettersson D500X and the Elekon Batlogger C are the ones to consider.

All units record bat calls very efficiently, but the main consideration is going to be deployment times. The Batlogger C can last for 5 nights with the single included battery or 10 nights with the optional additional battery. The D500X can last for 14 nights. The SM3BAT can last for 18 nights. The SM4BAT FS and Anabat Swift can last for up to 30 nights.

Note that the SM3BAT can record from two microphones up to 200m apart, effectively giving you two recorders for the price of one (plus additional microphone and cables).

Unless you need two microphones, I thoroughly recommend the SM4BAT FS or Anabat Swift for their long deployment times and ease of use.

With all of these units you'll also get a free bat calls book worth £30: either British Bat Calls by Jon Russ, Social Calls of the Bats of Britain and Ireland by Neil Middleton et al or Bats of Britain & Europe by Christian Dietz & Andreas Kiefer or a £30 voucher.

I want you to be 100% happy with your purchase so call me on 0333 9000 927 for advice.

Warm Regards,

Martin.

Compact, lightweight, single-channel bat detector and recorder.

Developed specifically for bat research, the SM4BAT recorders combine innovative design with a new low-power processor and easy-to-use scheduling features. Available in full-spectrum and zero-crossing models, the SM4BAT will make bat research simpler, faster, less costly and more reliable. The SM4BAT FS creates high-quality, full-spectrum recordings that can be easily converted to zero-crossing recordings using free Kaleidoscope conversion software. The SM4BAT ZC creates zero-crossing files that optimize power and data storage.

Small, secure and weatherproof.

Designed around the footprint of 4 D-size batteries and made of rugged polycarbonate, the SM4BAT is less than half the weight and size of the SM3BAT. The integrated mounting bracket and weatherproof security cover keep the unit safe and dry in the most punishing environments.

Longest deployment times available.

The new, low-power microprocessor, combined with 4 D-size batteries, enable the longest deployment times of any other bat recorder available. The SM4BAT FS has a recording run time of 300 to 500 hours depending on bat activity and other factors. The SM4BAT ZC run time is even longer. See Specifications for details.

Easy to program.

To get you started quickly, the SM4BAT features a brand new, easy-to-use, Quick Start menu and Scheduler. Use built-in schedules, or customize them for your specific recording needs.

Available GPS accessory to set clock and location.

When deploying multiple recorders, use a single GPS accessory to automatically set the date, time and location settings of all recorders. The GPS accessory can also be attached to log the recording locations and path for mobile transects.

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."
