In Topic: Mounting both Keldan's and strobes

22 March 2017 - 11:39 AM

I  attach focusing lights to the sides of my ULCS arms by mounting a simple ballhead to the arm while using a large washer for the bolt. The bolt runs through the latticework of the ULCS arms. I found this jpeg on my HD from a couple years ago. It shows my gear after arriving at one of my salmon sites but after putting on my waders (topside shoes in pic). The rig closest to the back of my SUV has a light (Fisheye light) on one of the balls while the other has a Seacam clamp on it but no light. You can see the large washer from the side on the unused side. A similar arrangement would likely also work with Keldans equipped with a standard ball fitting.

I'm also interested to hear about this one, and would LOVE to see a side by side with the Canon 11-24.

Ditto here!!! And Aloha! - I am currently right next door on the Big Island.

In Topic: RETRA Strobe Thread

Many thanks for setting up the FAQ page.  It has a great amount of information and answers all of my questions, and even more.  I will check it regularly.  I have to say your responsiveness is very impressive, as is this new product.


I have a general question here , Retra offers a variety of electrical cable connection options when you order (S&S 5 pin, S6, Nikonos 5 pin, Ikelite 5 pin are the options listed).  I plan to use this strobe with optical cables on an Olympus EM1 Mk 2 in a Nauticam housing, so the electrical contacts are secondary.  But, still, If I ever want to go to electrical cables for ultra fast recycle time, which is best to order?  It seems like the Nikonos 5 pin is pretty universal, but I can't really tell.


Any advice on this?  I think I ordered the S&S 5 pin but hopefully i can change that if i did not make the best choice, since production is so far out

Keep in mind that the choice is for the strobe bulkhead. One can get cables to N5 (housing bulkhead) from any of the listed bulkheads. I assume the Nikonos bulkhead is for use with Nikonos cables (those made by Nikon) so are a bit defunct. Both Inon and Sea&Sea use the S&S cables making them the most widely used. Number 2 is probably S6 but mainly for Eurostrobes. However Ike is probably more common in N. America. Your choice will dictate which brand cable you will be buying.

I have two on order as well. Hope they arrive before the end of this year's salmon spawning season. Looks like they will be much better as a single strobe positioned at 12 o'clock for fisheye lens shots (SOP for me) compared to the Inons. I will report back to this thread.

In Topic: Having to open housing to turn on electronics

08 February 2017 - 05:42 PM

Sounds like yours us working great, I am very surprised that for 500 dollars this problem has not been resolved

In addition it didn't even come with a battery, I had to buy that separate for 50 dollars then another 50 for a charger

I now find myself having to have to buy 4 batteries to accommodate repetitive liveaboard dives making my total cost 750 dollars and I still have to open the housing just before every dive

Yikes!!! Is there anyway you can retrofit to old fashioned cables? Are limited to fiber optic synchronization with your underwater strobes.


Update: I performed the overnight test. Left the camera with flash mounted on it (as above) all night - both left powered up and allowed to sleep on their own - both woke up on touch of the shutter button this morning.
