In Topic: Aquatica AD500 flash trigger not triggering strobes

17 March 2017 - 08:10 AM

i used the turtle on my last trip.
With the right combination strobe / cable it worked fine. I normaly use manuel mode.

I was trying with Manfred Werner from unterwasserkamera.at some things,
and he told me today that there is a known problem he heard from the turtle tecnican, with specially the Nikon D500.
I got a mail adress and will discuss this next week direct.
Something with lcd back light that causes a problem.

As soon i know more, i will write here.

@ Tim
worked fine for me manual on the trip.
Have the Aquatica here as well, but had not enought time to test them side by side.

Will do that and then write it down.

how is the connector made in the Aquatica housing?
Can you maybe send me a pic from inside and outside?
I have a Hugyfot housing and the Aquatica and the Turtle led trigger.
The Aquatica had to be tuned, was to big and the Leds are not good placed for me.
The Turtle has the possibility to place the leds where you need them.

But to come to your problem:
The S&S strobes are harder to bring to ignition than the Inons....
Have tried several combinations strobes and also important optical wires.
The D2 was the hardest for me. Needs absolut exact positioning of the light in and out point.

Have you the possibility to borrow a Inon strobe? Type 4 makes it easier ;-))

Try moving the plug of the cable just a little bit when testing, maybe you find a position that works, or maybe the Sony style adapter has a different distance / position of the leds.

Attached sheet shows my tests with the turtle and all strobes i have ( D2 borrowed ) and cables.
The Aquatica works sometimes good, sometimes bad......
The Hugyfot housing is great, but the light connection needs a little tuning.

Red - no ignition
grey - ignition
blue - ttl too dark
yellow - ttl too bright
green - ttl ok

As written above, the experiment shows that the D2 works on my housing, when i push the plug a little sidewards. 

But thats not a option underwater.
I am not an octopus ;-))

Hi Stephen,
very nice macro shots! What have you used for that?
The WB is sometimes tricky ;-))

Thanks for the cenotes / caves, its time to go there again....


In Topic: Need some dome port mod advice

05 March 2017 - 12:12 PM


can you try out if the distance gets a little longer, it will still work?
If so, you could attach a M67mm to Inon AD Mount on the dome, and the opposite on the housing.
