I wouldn't have thought of a pole mount as POV, but maybe the idea is that you're holding it yourself as opposed to someone following you around.
Personally, I'd just specify "pole mount" or "helmet mount" to avoid confusion.
Yeah, that's me, Tracer Bullet. I've got eight slugs in me. One's lead,
the rest bourbon. The drink packs a wallop, and I pack a revolver. I'm
a private eye.
