This patch is not only from one of the greatest 80's movies ever, it represents the SpookHunters in two ways.
The first is the 'Never Say Die' attitude. If at first someone says we can't do it, then we're going to prove them wrong and do it!
The other way this patch represents the SpookHunters is the way the kids in the movie were a bunch of outcasts ad rejects. In the world of ghost hunting, that's how a lot of the 'professionals' view us...and we love it!
