Hi there,

What can I say about the Wildlife Acoustics MINI BAT?

If you're looking for a static full spectrum recorder to leave out on site, the Wildlife Acoustics SM4BAT FS & MINI BAT, 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 SM4BAT FS and Anabat Swift can last for up to 30 nights. The MINI BAT can last for 30 nights on four AA alkaline batteries (up to 150 nights with six 18650 lithium ion batteries).

I thoroughly recommend the SM4BAT FS, Anabat Swift or MINI BAT for their long deployment times and ease of use.

With the SM4BAT FS, Swift, Batlogger C & D500X 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.

Note that deployment time is now 30 nights on alkaline and 150 nights on lithium ion batteries!
The new MINI BAT is only £730 or £760 with SanDisk 128GB SDXC card and four AA alkaline batteries (18650 li-ion battery pack available soon).

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.

Download SM4BAT FS User Guide - English - Spanish (Manual de usuario) - German (Bedienungsanleitung) - Chinese (用户指南)French (Guide de l'utilisateur)Japanese

The SM3BAT and SM4BAT FS implement a serial communications interface in support of wind energy SCADA systems to report possible bat activity. With firmware version 1.3.3 and later of the SM3BAT, or SM4BAT FS recorders produced with serial numbers greater than S4U06942 (shipped on or after March 12, 2019), the recorder responds to serial requests with information including cumulative number of bat passes and pulses detected as well as timestamp, voltage, temperature, and flash card capacity information.

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."
