Simple to build, easy to use

Easy to build and very simple to use. All working fine and have had many hours of fun already detecting bats in my local area.

A simple construction kit IF you know how to solder!

This is a very simple kit but you MUST know how to solder and have at least as BASIC level of electronics skills.
If you have never soldered or assembled any electronics kits then this is NOT for you.Read full review...

Bat detector

Very easy to put together, works very well, I would prefer it to be in a plastic box. But I still like it.
