Camera Dojo Wireless Flash Triggers

receiverYou may have noticed that I am now offering new products on the Online Store designed to help people get started with lighting on a budget. I have hand-picked these products to make sure they offer the best value and features for the price. The first product was the YN560 speedlite and the next item is these four channel wireless flash triggers. These wireless flash triggers are very similar to other products on the market with a nice little twist, mine come with a built-in umbrella mount allowing you to turn any tripod into an instant light stand.


These are four channel wireless flash triggers for using off-camera flash with either speedlites or studio lights. The transmitter can be triggered either by having it on the hot shoe of your camera or via a PC Sync cable connected to your camera body. The receivers can fire a flash either from the hot shoe or via PC Sync as well. Unlike many similar products available, these also include a built-in umbrella holder.


  • 4 channels with hot shoe connector for external flashes
  • Transmitter Power: 23A 12V battery
  • Receiver Power: 2 AAA Battery (Not included)
  • Maximum Working Distance: 30m (open area, without interference)
  • Operates on Frequency: 433MHz
  • Sync speed up to 1/320s (depending on camera)
  • Standby time: one year
  • Triggering life: up to 20,000 times

The only real setup you need to do is to make sure the switches on the transmitter and the receiver are set to the same channel. Press the test button and make sure the LED on the receiver flashes. If the two are talking you are good to connect your flash to the receiver and put the transmitter on the camera.

In my tests I can reliably get 90 feet of range, any more than that and reliability starts dropping fast with almost no firing occurring at 100’.


receiver2There is nothing really magical about using wireless flash triggers, you press the shutter and the flash goes off. What really matters is being able to put your light where you want it, when you want it. Over the years there have been plenty of times when I wanted to set up a quick remote flash but my light stands were out in the car or worse, back at home. However, I always have my tripod with me attached to the side of my camera bag. With the built-in umbrella holder I can now pull out my tripod, put the flash trigger on the tripod, and pop in an umbrella for a quick lighting setup.

If you are expecting complete control of your remote flashes just as if you were using the wireless system built into your Canon or Nikon brand flashes, then your expectations are going to be off a bit. These wireless triggers are designed to fire remote speedlites or studio monolights that have manual output control. Once you manually set the power output on the flash, then these are good to go.

In the Camera Dojo Store we are now selling these wireless flash triggers as a kit with a transmitter and two receivers for $49.95 and additional receivers for $19.95. Until the end of November, get 15% off with discount code Dojo15. Check them out at the online store at We also have a mini-site for all of the lighting products at

    What brand are they? I'd like to read some reviews on them.

      We are getting them directly from the manufacturer and it is the same product offered by a number of places as the improved version of the Cactus V2 PT-04. If you google on PT-04 Flash Triggers you will find hundreds of reviews of them. The main difference between the original Cactus V2 and this model is improved reception, a different receiver design, and mine have the built-in umbrella mount so you can also use a regular tripod as a stand-in light stand.

      Quite a few people are buying them from us right now so I expect to start seeing some comments in the forums about them very soon.

    Just got my flash triggers today and did some test shots. Everything worked great, for $49.99 these are a steal! Just remember they are for manual flash only, which is a great way to really learn to use off camera flash. I have two holiday family portraits to shoot this weekend and I'm looking forward to using them. I'll be buying one or two of the YN560 speedlites soon to supplement my Canon 580EX ll.

    Thanks Kerry!

    I am interesting in purchasing your wireless triggers. But when you say only in manual mode, is that the only mode these trigger work.
    Sorry little confuse.
