This is a 1 degree spot meter and a well used one at that. Comes with strap and leather-ish soft case. This thing is dead on accurate at midday. Unfortunately, as it gets darker, the further off it is. By sunset it's off by as much as 1 stop, compared to my EOS-3.
I had one like it, with the needle it was off 1/3 stop from my seconic flash meter, and pretty consistent, once you run a test with your spotmeter/camera/film combo you will be right on the money, also make sure to get that lithium battery for consistent readings.
