Cactus Wireless Flash Trigger V2s

I just received the Cactus Wireless Flash Trigger V2s from Gadget Infinity. The cost was $32.95 plus $5.00 for “Regular Airmail.” It took about a week to arrive from Hong Kong.

My goal was simple… eliminate the PC sync cable from my camera to the strobes in my very small studio (as cheaply as possible).

The new setup: The receiver is plugged into a Novatron M500 using an old PC Sync cable. The transmitter is on my Canon 40D.

Overall it works ok. There are a few quirks that may be specific to my setup.

1) I must use 1/200th shutter speed. Anything else results in a partially dark frame.

2) Occasionally, it doesn’t trigger the strobe. Maybe 1 out of 20 times. However, I think this is a cable contact issue. After twisting the connection to ensure it is well seated, I’ve gotten better results.

The range is more than acceptable for what I need: 150′ (45 meters) indoors with no obstructions. Your mileage may vary.

Packaging is pretty simple.


The pc cable fits snug, but I found twisting it after inserted ensures fewer failed shots.

It includes this flash stand (that I doubt I’ll ever use). It’s hidden under the packaging. If you aren’t looking for it, you’ll accidentally throw it in the trash.

Transmitter on the Canon 40D.

Update: Camera Dojo also has a good review of the Cactus Flash trigger on their site.
