sea and sea y3-d3 mk ii sync speed

[A Bajo]

I have the ys-d3 mk ii. I am playing with it at home before a trip. It seems like every second photo is completely black. I am not rapid firing or anything. So I was trying to find the sync speed for the strobes but don't see it anywhere. I am taking test shots at different power settings and consistently every second shot is black.
I'm using a Canon R6mkii.
edit- i realized I had the canon on high speed photo and maybe was taking two fast shots each time- I am going to experiment with other settings but still would like to know the sync speed.
thanks

Your camera has the sync speed constraint, not the strobe. At maximum power, full dump, your YS-D3 has a flash duration of 1/600 second. The surface GN is 33. If you had a camera (leaving HSS out of the discussion) capable of greater than 1/600 second sync speed you would have to be concerned about cutting into the flash output, but you do not as your camera sync speed should fully envelop the shorter flash duration.

Your Canon R6 has a X-sync maximum speed of 1/200 second with mechanical shutter (1st curtain) and 1/250 with e-shutter.

Maybe set your camera to single frame only and 1/200 second or less.

thank you, I did go to single shot after the post. I'm pretty sure the problem was I was trying the higher powers and not waiting long enough. thanks

The oldest trick in the book, set your rig up, stand in front of a mirror and take a picture. You should see your strobe(s) brightly lit in the mirror image. If not, you are not syncing.

Failure to sync can be complicated with some strobes. YS/S&S optical sensors are not very sensitive and need good optical cable, also there is the issue of sTTL, preflash, no preflash, in your camera settings etc.
Strobes set to TTL will need a preflash from your camera to run TTL in your camera settings. If your camera is set for Manual strobe, no preflash and your strobes are in sTTL you could have a sync problem. Assuming optical cables and realizing the YS-D3 does have an electrical sync option.
