I have a s 358 and use it indoors and out for continous light and flash. Flash fill too it is very useful, it is a great meter. I pickedup a 5 or 10 degree (forget) spot attachment from EvilBay and have not tried it yet. No instructions came with it.

So I wonder if someone can help the OPster (SafetyBob) and I know about usage. I know there are dip switches in the 358 and do they need to be set in any way to use the spot attachment?
