Need a clip on, wireless mic for Vixia HF R600. What is it called and where can I get it?

I want one with a batter pack I can tuck away and then clip the mic on my lapel. Have been searching the net and have no idea where to find what I'm looking for. Best Buy was no help.

I have this unit from Amazon.  Reasonabbly priced and works very well.  Comes with both lavalier and hand mike.  Actually this mic works better than my $200 desktop unit. when in this unit.

Limitations:  Monural only, but received supplies one channel to both sides of the camera input.  A mic with a stereo jack will not work with the transmitter.

I really could use a system with two mics but all those aree a bit out of my price range.  

Requirees 9v batteries.  I'd rather have AA since i have a stock of them in my bag for my LED lights.

Very happy with this system.  Req
