Sekonic L-308.... S, maybe? I think the versions are B, S, and D? Anyway, I have a 308B, earlier version, and it is my daily meter. Goes in a jacket pocket, always ready to be pulled out to check. I use it on incident all the time. Large simple readout. I set a shutter speed based on my basic shooting conditions and do the math if I need to make a change. Meaning that, for example, if it tells me that at 1/125 I should be shooting at 2.0, and I want to shoot at f5.6, I use 1/15. Simple enough... well, it works for me, a simple readout of a shutter speed and an aperture. Some people might prefer dials and such.
