Magenta 4 Bat Detector

Magenta 4 Bat Detector – A great entry point into the world of these amazing flying mammals. A wonderful device for the whole family.


The Magenta 4 bat detector is a fantastic device for discovering these amazing flying mammals.

By using special electronics the detector can pick up sounds given off by the bats that are inaudible to humans. This is then converted to a sound that humans can hear.

The Magenta 4 bat detector includes a high level speaker which is weather, audio input, and a jack for headphones.

Bats make up almost a quarter of all of the mammal species in the United Kingdom but these fascinating mammals are suffering a noticeable decline throughout the country.

Why we love using bat detectors: “It is incredible how much of our wildlife only appears once the sun goes down. There is something magical about hearing the clicks and ticks of bats as they fly around your head on a summer evening”.

1 review for Magenta 4 Bat Detector

  1. Elliot Falkus

    I had been looking around for a well-priced Magneta 4 after I used a friend’s and saw how much more amazing my bat walks could be. I ordered online from onestopnature and my detector arrived in less than 24 hours from half the country away! Very impressed by the online store and service.

    The bat detector itself is a great beginner’s bat detector if you want to just listen to the range of bat noises and comes with a useful little reference sheet, noting the relevant frequencies for each bat species.

    Amazing product, amazing service, would definitely recommend for any bat lover, an excellent investment.
