Impact PowerSync16 DC Radio Slave System

I added this to my bag and the first day out, it worked perfectly. I was doing an on site glamour shoot and needed the flexibility / mobility.
I shoot with Canon gear, attached it, and didn't look back. I connected it to my studio lights, then even tried it with my EX480 flash.

I would definitely recommend this.

I HAVE HAD NOTHING BUT PROBLEMS WITH INFRARED TRIGGERS I HAVE
TRIED SEVERAL BRANDS AND THEY ALL HAVE HAD ONE PROBLEM OR
ANOTHER.
I BOUGHT THE IMPACT POWER SYNC SYSTEM AND IT HAS WORKED
EVERY TIME NO MATTER WHAT THE LIGHT SITUATION
I HAVE TWO RECEIVERS AND ONE TRIGGER AND PLAN TO BUY AT LEAST ONE
MORE RECEIVER

[...] these don't seem to give enough voltage to power my Sunpak PZ42X. They trigger the flash but it only looks like .005% of the light is leaving the flash. I see a thin rectangular blip in the flashes' actual light tubes when I press the shutter or test button, nothing else. Tried this with and w/o the Impact Sync Hotshoe Pc cord for Pocket Wizards. No biggie tho', I've been planning on upgrading to a Metz or Canon 580, now it's just sooner than I wanted to. I've had 2 of the Sunpaks lose their tension, I'm done with them. Thought I could squeeze one last job out of them. These are a little frail buildwise but otherwise the trans fires the receiver every time so far.

All i have to say is : it's my first time using triggers and these worked excellent everytime for what i do, if jobs get technical in the future then i will just upgrade,but for now i'm just loving photography more and more because of these.... hey i bought 2 sets plus 2 extra receivers for a 2 photographer shoot at a large function and they all worked fine. I know i'll be using these for a long time as long as they don't malfunction.

This is a great product, it works just as expected and for the price of one pocketwizard you get the job done, it works great with tripods and hot shoes.

Perfect for studios or outdoors.

This is one of the best value-for-the-money triggers in the market. Range is exceptional, getting farther and more reliable triggering than with PocketWizards, indoors and outdoors (must be the 2.4GHz at work). Better construction than Impact's PowerSync10: improved on-off switch, casing, and more compact size. Uses same AA batteries as Canon Speedlites, no need to carry spare AAA batteries like I used to with the PS10. Great improvement in Sync speed, matching Canon's 1/250, almost 2/3 stop gain there (PS10 had a 1/180 limit, but I typically shot at 1/160 for better results). Easy visual set-up for selecting any of 16 channels. Feels more sturdy when connected to speedlite via hotshoe. Nice sleek design. Overall, a great product. My only wish? That it could also control groups and power outputs/ratios remotely on manual flash settings for as many as 3 units or groups and high-speed sync above 1/250.

Can't afford pocket wizards, they also don't work with my Panasonic GH1. But these do the job, and at an affordable price, love em.
