Wildlife Acoustics have launched the new SM2BAT+ ultrasonic monitor. Superficially similar to it's predecessor, this new incarnation can now natively record in zero crossing mode as well as full spectrum. This is now implemented in hardware rather than the cumbersome software conversion previously. This should improve sensitivity as there were reports of the conversion of full spectrum to zero crossing losing a lot of weaker calls. The file format is now standard .wav format rather than the in-house .wac format which took an age to convert from. It will be interesing to see if Anabat comes back with anything in return now that PDAs are getting harder to source as they're being replaced by smartphones.
