So you want to buy one? Sorry, this is not a commercial shop.  

I realize that the device we created is a lot of fun and has a lot of nice features that you can only find the high end bat detectors.

I like to share the fun and for that reason I do share some boards and parts and sometimes partial kits. Have a look at the parts section. 

In the parts shop you can find a siple frequency division batdetector which is built and ready for use.

There is no intention to make any money on this, I am no company, this is just hobby. Therefor I cannot hand out any commercial invoice if I send you any materials.

You really do have to start building yourself or find a builder.

As a wise old HAM radio amateur to me. "Build your own equipment and you have lifetime warranty" This also applies to this project. 

There are quite a few people that already built one and some needed a little assistance, but do not hesitate to ask for help, I'll just be pleased to see an other enthusiastic user. I am sure we can find a way to get it to work.

Another option is to build something together in a bat-worker group. If just one skilled persons is available to teach others it is a great get together and learning experience.
