Does anyone know if its ok to dive without the sync port cover on, and no sync cable plugged in? Ive just purchased a z-240 type II from a shop who forgot to post it. They said that the sync port is sealed and ok to dive open. He said he was an inon service technician but im not sure if this sounds right.

If you mean the optical port, it's fine. There's no o-ring in the cap anyway, it's just there to block the light. I use them with the optical sensor exposed to trigger the strobe from a wired on camera strobe sometimes.

If you mean the electrical port, it's NOT FINE. Water and metal pins don't mix. The electrical port cap should have a yellow o-ring in it, and this should be cared for like other o-rings.

Yes I mean the electrical sync port on the back of the strobe. Not the optical one. Will it be OK for two days of diving on a holiday while I wait for the cover to arrive? Is it sealed like the in on service tech said?

No, it's NOT fine at all as the (salt) water surrounding the pins will lead to corrosion of them and generate malfunction of the strobe.

When you get a cap, make sure the 'O' ring is in good, lubricated condition.

The electrical port can flood the strobe!
