V4 and high speed sync
I guess there is no more forum for V4? So posting here instead.
It seems that I cannot use my Nikon SB600 flash unit and Nikon D90 with the V4 triggers in auto FP (HSS) mode..
Wondering if this goes for all Cactus models or only for the V4?

The Cactus V4 is a manual wireless flash trigger that doesn't transmit TTL signal. To enable wireless HSS triggering, you need a TTL flash trigger. That's why the V4 is not capable for FP (HSS) mode.
Other Cactus flash triggers are not TTL too. Because if we don't have TTL trigger, it will be brand specific and limit the usability for the flash and the camera.
