How can I find bats with the detector?
Build your own bat detector with this kit complete with detailed instructions. The kit becomes a high quality ultrasonic detector that lets you hear the bats you’re looking for. Everything you need is in the box which becomes the outer case for your detector. With 17 parts this is a fun project to make and use.

What does this teach?
Bats may not be blind but in the dark it becomes harder to see anything coming so bats use a type of echolocation to help them navigate. Echolocation is made up of soundwaves on a frequency too high for the human ear to hear as we only hear up to around 20kHz. Bats can produce calls at 40kHz or higher depending on species. The Franzis bat detector can transform these unheard frequencies into audible sound letting you hear where the bats are coming from. Other things such as electronics also give off sounds that are audible on similar frequencies - listen and see what you can hear.

How do I put it together?
Learn electronics and try your hand at soldering. Most of the components are already attached to the board, there are just a couple of components and connections to solder. Use the capacitors, resistor, potentiometers, microphones, speakers and more to create your detector. The detector had two knobs on the front - one controls the frequency which you use to find the specific frequency the bats are calling at and the other controls the volume of the speakers. This kit requires one 9V battery (sold separately, Order Code L46AL).

Rated 3 out of 5 by from no sure some quality parts bought this bat detector building kit yesterday from maplins it was sent free delivery it arrived today very quick i was impressed.till i saw a cardboard box inside parcel it put me off a bit as this was to become the main box but to my surprise the rest of components looked good i put everything together but in a plastic box i had it took 3 hrs to complete and works great iam very good in electronics but to the ordinary person putting this together its a bit far i think a plastic box should be put to the kit instead of that cardboard thing......

Rated 5 out of 5 by from Bat detector - success Bought this for an 8-year old grandson. He was not keen to learn to solder, so I did the necessary (fairly simple) soldering of wire connections myself. Detector works fine. So far have only come across pipistrelles. The big advantage of the detector is that it warns you when bats are present and greatly increases the chances of actually spotting them in flight. Used successfully on a number of occasions.

Rated 5 out of 5 by from best bat finder! Bought one for myself and was so impressed I bought more, as presents for mature offspring. If one can handle one's own instrument soldering iron, the kit is complete and simple, with excellent instructions. And it actually works! Note: needs a PP3 nine-fold battery.☺

Rated 5 out of 5 by from Wonderful! It took about half an hour to make and it works perfectly. I haven't tried it on bats yet as it is winter but it picks up the sound of me gently rubbing a finger and thumb together from twenty feet and the sound of a pin dropping is awesome!

Rated 5 out of 5 by from Bat Detector This works very well, the only downside is that it's a cardboard box and so will not last, so I will convert a smaller waterproof box at some stage. It would appear to detect bats going away as well as coming toward you.

Rated 1 out of 5 by from No sound at all Spent an evening checking and double checking the construction. Can't find any thing I did wrong, but can't get a peep out of the thing. A lot of effort and with solder best part of thirty quid for no result at all

I'm looking at this kit to use as part of a Science experiment in a school. We would like to build something to leave around the school overnight to record any sounds rather than listen in real time. Is it possible with this device? Thanks.

Asked by: L Dormand
I am sorry but the item in question does not support use in your intended application.
