60 day 100% Satisfaction Guarantee & extra year's warranty

The Anabat Express and the Wildlife Acoustics SM4BAT ZC are both zero crossing recorders for leaving out on site.

They both perform the same function and give the same results - ZC files of ultrasonic calls, i.e. bats.

The differences are in the design, construction and weight of the units.

The Express is a nice lightweight unit (476g with batteries) that's easily and discreetly deployed and it has a built-in GPS unit. It is programmed via a computer and can be deployed for up to 14 nights.

The SM4BAT ZC is heavier (1.2kg with batteries) and more obtrusive and the GPS is optional (uses the same GPS as the EM3). Programmed on the front panel and easy to check and reprogram in the field. Has an integral security case. Deployable for up to 50 nights.

Choose whichever one has the features that suit you best and if you need some help choosing, call me on 0333 9000 927 (+44 333 9000 927 from outside the UK) or email me.

Warm Regards,


Choose from the Express and the SM4BAT ZC

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."
