Hi there,

What can I say about the Wildlife Acoustics SM4BAT ZC?

If you're looking for a zero-crossing recorder to leave out on site, this is the one to get unless you're happy with deployment times of only 14 nights.

This is the new benchmark for long-deployment zero crossing recorders and it comes with my exclusive 4 year warranty.

If you're happy with shorter deployment times, perhaps the Anabat Express would be a better choice; with up to 14 nights deployment on one set of AA-cell batteries plus a 2 year warranty, exclusively from me.

Alternatively, the new Anabat Swift offers comparable deployment times and can also record in full spectrum, though has a higher price tag.

With all SM4BAT FS & Swift 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.

Your SM4BAT ZC is available with or without the SMM-U2 FG mic with 5m cable, two SanDisk 32GB SDHC cards and four alkaline batteries.
60 day 100% Satisfaction Guarantee and exclusive 4 year warranty.

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."
