Bat detectors

[TLM]

Does anyone have experience on these? I probably could build one but I am lazy and I don't have ready access any more to some of the helpful instruments I used to.

Thinking about a self sufficient one or one that could be connected to a phone or tablet.

Explain the use please?

Basically a very high frequency microphone with amplifier. After that there are several possibilities: using one of several ways to change the inaudible tone down to audible range or make a frequency analysis and show a visual pattern of the voice. The very basic detector apparently just shows ultrasounds without any way of identification, the two previous ones can be used for that.

Aha. Sorry, a medical person here....

So you are a Twitcher but on bats? Batman? Batista? Baterrer? Batophile?

Plenty of bats here. At sun set, if ?I sit in the pool without moving, the bats swoop down almost to my head, hunting the mosquitoes that are like a cloud around my head.
Never touched me. Expert flyers, much better than the birds!

I mostly watch birds but at night there are not so many but a bat is a flying creature of a kind..

I have a Magenta 5 (the 4 is a bit cheaper) - works fine as a basic detector.

Shop around as prices seem to vary wildly.

Yes, I used the two mentioned in the article below. I thought the cell-phone based one (Echo Meter Touch 2) was awesome and easy to use. I especially like its auto-classifying feature.

The Ananbat is more of a scientific tool.
