Hi - definitely a spindle / egg cowry species. I found a similar pictures here:

 

 

 

Referred to as a Shuttlecock Egg Cowry.

 

I am no expert but hope this helps.

So when you mentioned on a dive that you had the problem and shutter release was locked up. Did you change your strobes back to manual during that dive? I just want to make sure that if TTL misbehaved, at least going back to manual would be a good back up. However, if the board decided to act up and there was no way to get around it while on a dive, may be it is not worth bothering with it, I guess.

Hi -- this happened before diving and I dived cameraless!! I can only assume it was a circuit board issue as when I tried a nikon external flash everything was fine. After a third attempt at home with the strobes they started firing normally - beats me but it was very annoying. With the switches on the board both are down - down for inon on left and down for TTL on right. The fact that TTL switch is on does not (as I understand from reading here and elsewhere) preclude the use of manual settings.

 

On the inons I just turn the strobe dial straight to manual. When I use TTL on the strobe, despite the fact the ttl converter itself is lighting to confirm TTL (green light) and the strobe itself has TTL confirmation light (green as well I think) the shots are always badly underexposed. I am not having that problem in manual mode, but it did not matter what I did on the weekend, nothing worked, despite trying all switch settings, changing the batteries etc, I will have to use trail and error over the next few days and if the problem persists I will reinstall the original flash trigger and send the TTL one for repair / replacement as it is under warranty.

Hi Yes - it has a manual and TTL switch on the circuit board. Although mu understanding is that by using manual mode on the strobe itself it overrides it anyway. In my case the issue may have been strobe related but won;t be sure until I replace both strobes in the future. I am holding off until Inon decide if and when their new model will release and the retras have had more feedback! Best of luck
