Between both hand resisted and dynamic tension (antagonist/opposite muscle) resisted, you can do four way neck work, anytime, anywhere.
It only takes a minute or so to get a noticable neck pump.
I’ve never had access to a good four way neck machine. My high school weight room had a cheapo one that was broken half the time.
Fortunately you can get the effects without equipment, either hand resisted or without even that by the use of dynamic tension.
I suggest regular neck training.
It can save your life.
Besides it’s unbecoming to be a weak little pencil neck geek.
