Haven't seen those before but that may be due to the fact that it says "TSET" under the test button.

Selbosh [deleted] says:

Their newsletter says that they're new and supposed to be an improvement on the Gadget Infinity style ones because they're smaller.

Another cause for concern would be the lack of channels (unless that's what L and W are) and what the bottom of the receiver looks like (how to attach it to a light stand). I've sent them a question about the latter

Selbosh [deleted] says:

$27.99 USD, which is about the same as typical PT-04/TM ones (the GI Cactus knock-offs).

I think now that the "new function" of controlling the flash with "receiver only" just means there's a setting where you can test the flash with the test button but the receiver doesn't respond to radio signals.

I just found this on what looks like YongNuo's HK site:

The bottom of the receiver is a screwmount with what looks like a battery door.

Edit: Also, the button on the receiver says TSET, so it's either a typo, or it's not a test button.

2，Use only the receiver to control the flashlight. (New Function)

elv0000 says:

The receiver switch appears to be a 3 position switch with OFF in the middle and two modes W and L. ("powerswitch/function choice")

and quote "Use only the receiver to control the flashlight. (New Function)"

That would make me think it has an optic slave built in........ but I can't see any light sensor? I wonder what they mean by that and what the other function is.

Back to the old CR2 battery :(........ but it says its a PT-04TM so hopefully compatible (and works as well as) the other PT-04TM.
Posted 42 months ago. (permalink)

Selbosh [deleted] says:

If it's compatible with PT-04TM then it would be a good choice for joining my current set of triggers, as one of my receivers has a broken stand.

There's a hole above the tripod screw on the bottom, which could be a sensor or just the place for the channel buttons (though I'd expect them to be orange like the transmitter - unless they've taken the circuitboard out for the photo)

DealExtreme do the crazy 100m range ones for $30. They're pretty similar to these ones but without the optical slave, longer range, 16 channels and a taller transmitter. The receiver also has a PC port, which I think the new ones lack (although PT-04TM receivers don't usually have a PC port anyway)

Thats a shame... also means its back to square one with, range, flash compatibility, reliability, details again. The more expensive triggers above have issues with low trigger voltage flashes and the 430ex (unlike the PT-04TM... which is pretty well sorted (and AAA batteries)).

That's right. The manufacturer gave me instructions in an e-mail on how to use the optical slave. Forgive their fractured English:

Dear selbosh,

Thanks very much for your letter.

There are two functions for this products.
a), Use the transmitter and receiver to control the flashlight
b), Use only the receiver to control the flashlight.

b is the new function, when you use it, please plug in the flashlight to the receiver's hot shoe socket, then switch to "L" mode, press "TEST" botton.

The light sensor is the side of receiver, I marked it as picture, please kindly note. [They sent me an attachment with a label pointing out the sensor. You can see where the sensor is on this online pic]

Posted 42 months ago. (permalink)

ttmz says:

Thanks! I guess what I don't understand is how you would then attach this to, say, an umbrella bracket on a lightstand?
Posted 42 months ago. (permalink)

Selbosh [deleted] says:

Many umbrella brackets have screws on top, which in turn have hotshoe adapters added to them. You simply don't use the hotshoe adapter.

Here's an example of a bracket that would work:
cgi.ebay.co.uk/Calumet-Swivel-Umbrella-Adapter_W0QQitemZ3...|66%3A2|65%3A12|39%3A1|240%3A1318

I understand your problem, as I have a mixture of brackets and one of mine only has a groove for sliding in hotshoe feet, so it won't fit these receivers. It's a really cheap one though. I think most "decent" umbrella brackets have screws, with the option of a hotshoe adapter, e.g. the MPEX one:
www.mpex.com/browse.cfm/4,859.html
where you can remove the white thing on top and there's a screw underneath.

Gene's Pentax    says:

Looks like more and more flash slaves are getting the hint from Flashwaves. It would've been nice if the flash could be balanced on the receiver like Flashwaves. I wonder if this is as reliable. But for the price, it's probably worth trying at least once. I've ran out of patience with these cheap ones from China a looooong time ago. When will the others (AB, PW, etc.) get the idea and put hot-shoes on the receivers like Flashwaves and this stuff?

Interesting find though!

www.dpjphotography.co.uk    says:

I have got mine from HK. First impressions are good, they are built well, have a nice finish to them. They are fairly sturdy when you use them as a base, but wouldn't want them around any strong breezes. The radio signal is farly strong and works at a fair old distance - about 40mtrs at the moment, only a quick check last night in the car park. The optical slave works really well, better than my SKY4 versions, as it works at the same distance!! I will put up a better report once i start using them properly, but as of yet, they seem to be quite good. CR2's though, only bad thing i think.

www.dpjphotography.co.uk    says:

aperture prority - As far as the breeze, it is when they are used as a free standing base, the screw in connector for light stands is top notch.

As far as SB's, i'm afraid i don't know anyone who has one, sorry. The hotsho connector is pretty much a standar setup, so i would assume tey would work ok.
Posted 42 months ago. (permalink)

aperture-priority says:

OK, thanks for the clarification.

With the newer Nikon SB's they lock onto the hot shoe using a small pin that projects downwards into the shoe near the front. Those receivers look like they might have a small hole in the correct place, and I was wondering if they had been designed to work that way. Without the locking hole they are very insecure unless gaffer taped or fitted to a hot/cold shoe with locking rails.

I wouldn't trust my AS-19 flash stand in a breeze either, but there's always the potential to use a small table-top tripod (or gorillapod) to hold your flash if you really need it at ground level

The receiver is flat and has a tripod screw on the bottom. You put the receiver on your tripod or light stand with the screw on the bottom then put your flash in the hotshoe on top of the receiver.

Its more stable than the cactus v2s because the CTR-301 is flat.

tj! says:

I'm glad I came across this... I was just about to purchase a couple more Vivitar 285HVs and cactus receivers to go with them. I also need the stands and umbrella holder/flash mounts. I'm trying to get away with this as cheaply as possible since most of my funds have recently been drained on other things, on top of being a typical poor college student.

Should I purchase the trigger with two receivers and then another receiver, or should I just get a couple more cactus receivers (I have a transmitter and receiver)? I shoot both indoors and out, mostly full body/portrait (band promos and such, but none are in my stream as of yet).

If I were to purchase these (I have a Yong Nuo wireless shutter release and it's very reliable by the way) would it work with my current flash stand and mount (Mount/Umbrella Holder, Stand) and the pair I'd like to purchase (here) or would I need something else entirely? I'm just trying to be as cost efficient as possible, but I've heard plenty about the Cactus' unreliability and don't want to purchase more receivers if they are just going to fail after a short time.
I'm also trying to decide on hunting down cheap Speedlite 420ex or 430ex's, or just getting the 285HV's... but that's a whole different topic.
Posted 41 months ago. (permalink)

Selbosh [deleted] says:

It's got a lower profile and therefore it's more stable. Your flash isn't going to fall over because there's no swivelling L-stand you have to tighten. There's no weakpoint where the L-stand meets the plastic, so it's less likely to break. It's also got an optical slave capability, so you can mix them with any other type of triggers when using this function.

The first umbrella brackets are great (I have one) but they have no screw thread on top, so you will need to buy one of these with it, or you will need to find an umbrella bracket with a 1/4" screw thread on top.
The brackets in the 2nd link look like they have a 1/4" screw thread and a removable coldshoe, so they're ideal!

This is what I received in reply:
"Hi friend,

Just the straight PT-04's.

The only way i could see doing this is to use a Hotshoe with PC or Mono Port, then cable to flash. Probably defeats the object of them being low profile.

You seemed to have put your 301s through a pretty good test and wondered if you still think they're worth ordering? I like the Cybersynch as well but to use them with a 102 or the 600 requires a PC adapter which the 301s wouldn't.

Forget the PT-04 and definitely go with the CTR-301 model. Some facts:

1) I paid $39.99 for 1 transmitter and 2 receivers including batteries. Shipping was free from Hong Kong.

2) The CTR-301 is flat so it is much more stable when a strobe is mounted to it and it is mounted to a stand or tripod. The CTR-301 receivers include a standard screw socket on the bottom for mounting.

3) The receivers can either act as wireless receivers or as slaves for your strobes.

4) The receivers have an on/off button so you can turn them off when not in use and you won't drain your batteries.

5) The effective range I tested was 100ft. And I never had a misfire.

6) The transmitter uses a 23A battery and the receivers a CR2. And its easy to put the cover back on after the batteries are inserted.

7) You cannot attach a PC sync chord to it directly. I put a wein safe sync in the receiver hot shoe socket then attach a PC chord to the wein safe sync...works perfectly.

8) You cannot change the frequency channel.

For me these are much better than the Cactus V2s or the PT-04s and much cheaper than the PocketWizards. These should be the new standard for wireless flash use.

This was only for the sync cord? Or do you expect a high voltage strobe to kill these gadgets?

I do have some older flashes where I would ALWAYS use the safesync, or if I am connecting to studio lights I would use the sync chord as well.

When I use the Vivitar 285hv, I don's use the sync chord.

A correction: I would say the wireless transmission is good for 75 ft.

8) The transmitter and receivers have 4 channels. You can change the channels by toggling 2 dip switches.

HotStock - Yep super happy with them, i am getting good range, no misfires, they mount easy and ar very stable. All in, they are WAAAAAYYYYY better than any EBAY jobbies before them. I am happy using them on ANY of my older flashes, i have thoroughly tested them on all of the flashes i have, about 15, most of them older flashes, and i have had no problems whatsoever. I have an order in for another 1T/X and 2 R/X units.

Aron Durkin - I don't think you need any more proof. I have tested them to the limit, they fire constantly at around 125ft, the optical at around 75ft. No misfires at all, no random triggering of flashes at all. They mount to stands/tripods well, and form a stable base for your flash. They work well with older flashes, even with higher voltage. They work with other forms of EBAY triggers, i have used them in conjunction with my PT-04 R/X's and they improve the reliability of these units.

I think they are great, the price is good, they work well, yeah they are no P/W's, but for the money, they are a very good alternative. Hope the info i have given helps anybody who is thinking of getting these triggers. If you do, let everyone know how you get on with them.
