Am diving in the morning in Cancun with my new set up. Have everything set up according to the instructions and tested today. Found that the strobe is firing 2 times per shot instead of once. Is this normal? If not what setting could I have missed? Any quick help will be appreciated because if this is incorrect, I will be overworking the strobe and draining the batteries.
Thanks

Sue,
This is from a technician at Ikelite. You may have already received this response via your email inquiry to Ikelite.
That is normal if you are shooting in TTL flash mode. The double flash is
the preflash followed by the main flash. The camera determines the flash
exposure based on the preflash. It is OK, even preferable to use it like
that.
When you used the EV Controller before with other G series cameras, you
were using manual flash and there was no preflash, hence you only had a
single flash. If you want to use manual flash instead, the easiest way to
do that is to put the camera in manual (M) mode and the preflash will be
canceled, and you can set your flash exposure manually.
So, to answer your questions 1) Yes, that is the way it's supposed to work,
and 2) everything is working as it should. When using aperture priority
(Av), shutter priority (Tv), or Program (P) mode, the factory default flash
mode is TTL (aka "Auto" flash in the camera menu) and that means there will be a preflash.
