Sorry if this is in the wrong section...wasn't sure. I just wanted help finding a laser-line projecting device similar to what I saw when I watched the Championship games on YouTube (used for checking if a ship is in firing arc boundaries). I can't seem to find one on Amazon, so please share specifics if you have one (Product exact name, manufacturer, place where you bought it, etc).

Thanks in advance!
