Pentax 1 / 21 Spotmeter

[Brad Bireley]

I have acquired a Honeywell Pentax 1 / 21 Spotmeter. What batteries that are made today will work? Thanks!

It might be the PX28 little barrel size in common with that whole series of spot meters down the line. But different brands nowadays tend to have different marketing numbers with the PX28 in fine print. I'd stick with Duracell Alkaline or Varta silver oxide ones.
