A different version of the standard Sixon is the Sixon Dual, this meter
made for the US market only has the ASA film sensitivity on the scale
while the others types have DIN and ASA settings. The reason why this
meter is called the dual is because of the different values of film
speed on the scale of the film sensitivity knob. The dual has
two dots a red one and a black one and the same for the numbers on the
scale, red ones and black ones.
Other version are the Sixon and the Sixon Color Finder.
