Cactus V5D V5 Flash Remote, Black

I purchased two of the Cactus V5 sets to use as a remote flash trigger and remote shutter trigger, and after eight months I can say the V5’s are absolutely fantastic. I have triggered many thousands of photographs and strobe firings and the Cactus V5’s have worked flawlessly each and every time.One of the greatest features is each unit is both transmitter or a receiver, selected by the power slide switch on the side, slide it one way it transmits, slide it the other way it receives. If you only buy a pair you won’t see this as an advantage; but for those of us that use more than two its a huge feature providing tremendous flexibility. For example, I have four V5’s and have used them in the following configurations:1 V5 set to transmit on camera hot shoe triggering between 1-3 V5 equipped strobes set to receive. I can set each flash to a different channel and by changing channel on the transmitter select any individual strobe OR by changing to a group channel I can fire them all.Yesterday I was firing a complicated setup:#1 V5 in my hand to transmit, #2 V5 set to receive and plugged in to the camera remote shutter port; #3 V5 on my camera hotshoe mount is set to transmit and has a bounce flash “daisy chained” on top and finally #4 V5 is set to receive at my umbrella reflector. When I press the button on #1 half way, #2 focuses the camera. When I push #1 button in all the way #2 trips the camera shutter, the camera hotshoe tells #3 to fire the bounce flash and the flash connected to #4.I hope that made sense. With any other brand, to do what I did in my second scenario I would have needed to buy a second transmitter, but with my Cactus V5’s I just flipped a switch.I’m going to buy two more to increase the number of flash units I can fire wirelessly, and I’m considering buying more after that just to keep on hand as spares, I expect to be using my V5’s for many, many years.
