Product Highlights
  • Designed for Hot Shoe Mount Flash Units
  • Triggers Remote Flash to Fire
  • Range Up to 60'

The Dot Line Hot Shoe Photographic Slave Flash Unit is a slave flash unit with a hot shoe, designed for hot-shoe mount flash units on cameras. It also fits most flash accessory hot shoe mounts. This unit employs an optical triggering that requires no electrical connection to the camera. However, for this to work, there must be a master flash electrically connected to the camera. The slave attaches to the remote flash via the built-in hot shoe, senses the light from the master flash, and then triggers the remote flash to fire. The sensor cell must be positioned so that it can "see" direct or indirect light from the master flash.

The bottom of the slave has a female 1/4-20 thread to accept any tripod or ball joint head. The slave also features a standard accessory foot that can be used for mounting into a standard accessory shoe. The unit boasts a range of up to 60' (18.3 m) from the master flash. No batteries or external power are required, other than the light from the master flash.

Dimensions 1 x 1 x 1" (2.54 x 2.54 x 2.54 cm)
Range Up to 60' (18.3 m)

    After some research I've noticed that so many photographers having problems of synchronizing the second flash with their master. I've found the perfect solution and finally could use my old Minolta 360PX flash unit. This Slave triggering Unit by Dot Line works fine and all the time with my Canon 580EX attached to my Canon EOS 20D DSLR on the flash bracket. However, this is the most important fact to consider, you have to forget about using your dedicated to your camera flash unit (in my case Canon 580EX) in ETTL or TTL mode and switch it to the Manual mode if you want this optical trigger unit to fire synchronal with your master. The reason is because the ETTL usually uses the pre-flash to set the flash exposure just before firing the main flash and that pre-flash will trigger this optical slave unit. As the result, first the second flash won't fire the second time because it was just discharged, second your camera will measure absolutely wrong ambient lightening (much brighter due to the additional second flash firing). So, you would end up with heavily underexposed images. You must to use both flashes in the Manual mode and calculate the power ratio between both flashes on your own. Well, the way I do that is I start with my Canon 580EX in 1/8 of flash duration (power) using it as a fill light while my old Minolta 360PX attached to the optical trigger unit is set to the 1/4 of the full duration as a key light. Then I usually shoot some test shots (no more than 2 or 3) to find the perfect flash exposure by adjusting either or both of the 2 light source powers with very soft shadows on the subject's face to create that 3 dimensional perception images.
    If you understand the 2-light source exposure principles and methods, I would highly recommend this product for anybody who has an old unused flash laying around for nothing since the time of 35mm photography.

    I'm a Professional Merchandise Photographer, and an amateur/professional general photographer. This little slave worked great with my Canon EOS 60D and Canon s95 Point and Shoot camera and the attached Classic Canon Speedlite 380. Unfortunately, when the Speedlite recharged, and a new picture was taken, it did not fire the flash. The only time It did so was when i hit the Flash Test button on the back, then it would fire.

    That was more of the same with my Canon Speelite 430EXII but when it did fire, boy what a difference! The Slave flash was also a millisecond delayed, so you would essentially have to do a long exposure to see that second flash fire.

    For under 20 dollars, it was an interesting and fun experiment but I would stick to a true wireless trigger or a tethered trigger. The construction of the item was top notch, better than I expected, but that can only go so far when talking about flash reliability on the fly and when you just need everything to work.

    Inexpensive. Works fine up the it's listed range! I purchased two of these at the same time and one of them had a crooked sensor under the clear plastic housing. It functions but perhaps would have an altered angle of sensitivity, but I haven't tested that out yet.

        It does what I expected of it, enabling me to utilize some old manual flashguns, but both hotshoe attachments are loose and weak. OK if the gun is vertical, but not adequately strong if the gun is horizontal.

                Used them in a shoot this past weekend and they delivered big-time! Got perfect palance with my test shots and the actual shoot. No messy cords or batteries. Will probably buy a couple more just to have around.

                There is nothing bad about them.

                And, as always B&H Photo is my go-to vendor!!!

                      Hot shoe doesn't with Canon 430EX11 and 540EZ. I Contacted Dot Line thru their website and they never responded yet. These Slaves should be sold with a list of flashes they work with.

                        I haven't got to use this for what I need it for but have tested it.

                        This will help me to add fill on larger group shots I will be taking. I am using a Canon 50D with a Canon 430 flash on the camera. I have an older Vivatar 285 Flash that has been sitting but now will be able to acheive better group shots.

                        I tested it setting the slave unit at diiferent angles and positions with no problems. Works good...

                          Bought 2 of these to bring a couple of old flashes out of retirement. The slaves work absolutely great and function every time. It's a cheap way for me to add additional background lighting or a hair light in the studio, or add extra lighting in the field using otherwise useless old flashes.

                            I wish it was mentioned some where that it does not work with Canon 580EX II (and probably other Cannons), it flashes once and no more.
                            It does nothing at all with Sigma flashes.

                                I bought this to see if I could take 2 old flash units and make slaves for indoor bounce light in addition to the dedicated unit I have for my Nikon D80. I have a Sunpak 5000AF which was for my Nikon F100, and a Vivitar 4600 from the Nikon F3 (close to 30 yrs old)
                                With the newer Sunpak it does not work regularly. It probably needs to take time to recharge.
                                But the older unit flashes every time. So, for $24 I have a usefull slave for bounce light. FABULOUS!!
                                Someone should come up with a battery powered optical trigger for these older flashes.

                                  Connects to my 2nd speedlight and triggers it by the flash from my primary speedlight. Definately worth the money.

                                      I can confirm that this product works with current digital camera flashes that emit a pre-flash. (Older slaves that I had from film days mis-fire on the pre-flash and don't fire when the picture is taken with the main flash pulse). This one works just fine with my Nikon D5100

                                      I'm a Professional Merchandise Photographer, and an amateur/professional general photographer. This little slave worked great with my Canon EOS 60D and Canon s95 Point and Shoot camera and the attached Classic Canon Speedlite 380. Unfortunately, when the Speedlite recharged, and a new picture was taken, it did not fire the flash. The only time It did so was when i hit the Flash Test button on the back, then it would fire.

                                      That was more of the same with my Canon Speelite 430EXII but when it did fire, boy what a difference! The Slave flash was also a millisecond delayed, so you would essentially have to do a long exposure to see that second flash fire.

                                      For under 20 dollars, it was an interesting and fun experiment but I would stick to a true wireless trigger or a tethered trigger. The construction of the item was top notch, better than I expected, but that can only go so far when talking about flash reliability on the fly and when you just need everything to work.
