Sync cord end clip

Here's a little refinement after the initial test dive.

This clip allows the raw end of the sync cord to be fitted and removed underwater. This will allow much easier rolling out of the long cord now that the little hooked clip is not permanently attached.

The clip is stuck to the strobe by double sided tape.

I have also made up a short optical sync cord for use with a slaved on-camera strobe. This means I can just use a single electrical sync cord for the main strobe instead of the annoying double electrical cord.
