Because of the nature of this product, my usual evaluation format will not be used. This will just be a brief informational page with a trio of photographs and a trio of spectrographic analyses on it.

This is a handy-dandy gadget that allows you to find out which circuit breaker or fuse controls which AC receptacle (or "wall outlet" or even "wall socket" if you prefer).

You simply plug the transmitter into the AC receptacle for which you want to find the breaker, then go to your breaker panel and "wave" the transmitter over the breakers in that panel -- a green arrow will light when you've reached the breaker that feeds power to the outlet you have the transmitter plugged into -- yes, it's pretty much that easy!!!

Product was found during one of our weekly garage sales in early-August 2011, and needs to be returned to my stepmother upon completion of testing.
Therefore, that dreadful "" icon will appear at once, denoting the fact that I no longer have the product for additional comparisons or analyses.
