Most small OC cans discharge in a stream
Good point. I was thinking of Fox Lab's 2 or 4 oz cans in "cone" configuration, were "cone" is being between a stream and a fog.
See
their page for a picture of the spray types.
I totally focused on my choice (Fox's "stream") and forgot to state my assumptions.
FWIW, Fox also has inert cans for training.
