PocketWizard PlusX Wireless Radio Flash Remote Trigger for Canon Nikon DSLR Cameras - Professional Photography Studio & Outdoor Shooting Accessory

I've used the Cactus V5 triggers for awhile and they are very good and reliable but there were too many problems with mounting, the battery door and especially the channel selection. First the mounting wheel was very stiff and I had to work it back and forth many tines to loosen it up, the PocketWizard mounts easily and solidly. The battery door on the Cactus is easy to remove and load but it doesn't take much to pop it open. Several times I went a bit crazy wondering why it wouldn't trip the flash only to find out the battery door had popped open while adjusting the flash, finally I had to tape it closed to prevent this problem, The PocketWizard has a very solid latch to prevent an accidental opening. The channel selection wheel is very hard for me to read, I would have to put on my reading glasses to see it, however they are very strong and trying to navigate with them on can be very hazardous, the PocketWizard has a very nice back lit channel selector, obviously a big plus for me. Also a channel can also be deselected to easily when making adjustments. The one advantage Cactus has over the PocketWizard is the ability to set the flashes on channels 2-5, test them with an an additional V5 on each channel, then after ratios are set they can all be tripped via channel 1, unfortunately the PocketWizard is missing this function but not a deal breaker for me. Overall I prefer the PocketWizards for the many reasons I have mentioned but I don't regret buying the V5's. I wanted to get into the strobist stuff as cheaply as possible and they are a very good alternative if you can live with the inherent problems although they are minor problems. I've found them to be very reliable.
