Men at work.

Took too long today trying to figure out what was wrong with a Safe Sync flash unit that I bought through Amazon from the US. It's not worth the trouble of packing it and paying the return postage but I'm convinced that it's a design fault. I know now that others have had the same problem, it won't work if the flash trigger voltage is over about 60v.
As the light was going I realised that I had no blip, so here is Paul laying a new bit of paving at the side of our house.
