Cheap B-foot for flute

Plug this at the end of your C-foot. You loose the ability to play the lower C (lower C# is still available) but you are now able to play the lower B !

I find this helpful too with the third octave : emission is easier and the tune is better so I use it even when I don't have low B to play.

Use tape to ensure air tightness and good adjustment with your C foot.
