I no longer have the .1 problem either. And yeah you loose showing voltage in wattage mode but at least the battery readout looks better.
I'm digging the Smart mode so far but I'm not sure I like the readout. I thought it would just be a smart feature in wattage mode, remembering your wattage settings for each coil, but instead it's its own mode with a different read out.
You choose Smart instead of Wattage, Bypass or TC....
Then use the plus/minus buttons to set your power in 1 watt increments for that coil....
Then when firing, this is the display readout.....
Works like a charm though. I don't have to change anything when switching between my .4 and .5 coils.
