270EX Speedlite.

These flashes include the 600EX-RT, 430EX II, 550EX and the 270EX. The 430EX II provides almost as much light
as the bigger 580EX II. This flash is smaller and less expensive then the 580EX II. Another alternative is the 270EX
flash. The range of this flash is almost as good as the 430EX II. It is compact and easy to carry with the FlexTT5.
Note: The 600EX (not RT) has not yet been tested.

AC7 Hard Shield.
<!-- --/>
To enhance the ControlTL™ System range performance when paired with the Canon 580EX, 580EX II and 430EX
flashes, PocketWizard developed the AC7 Hard Shield.
The body of the AC7 Hard Shield is made with a material that effectively blocks RF interference (EMI) from
clouding the FlexTT5 antenna. To block noise traveling through connections in the hot shoe, an electronic filter has
been added to a hot shoe built into the AC7. Combined, the AC7 shield allows the FlexTT5 to receive transmissions
at distances 300 to 500% farther then before and well within the range of most off-camera lighting needs. Read
