V6 in hand to change settings of the V6 on the camera?
Is it possible to use a V6 that I keep in a pocket to change the power settings of the V6 in Transit Mode connected to the the camera. That would be very helpful. A lot of times my camera is up high and I can't see the screen. I shoot home interiors and it would also be helpful to change the power output with a V6 when I am walking in the scene.
Yes for remote controlling the power output of a compatible TTL system flash mounted on another V6.

You will need:
3 x Cactus V6
1 x shutter cable
And enable the Relay Mode.
More information on setting up the Relay Mode on P.51 of the PDF User Manual.
Hope this helps!
