The SBC is also known as the Profisix in Canada and many other parts of the world.

The instruction manuals for many of the Gossen meters can be found on the Gossen site:

I've had my Profisix for almost 30 years, and it is a great meter.

I now have a Gossen Digiflash as well, for those times when I need something tiny.
