I'm confused. How does your hook stay open till it clamps on? I know how the 118 style one works, but this one seems fundamentally different.

Open is easy, You can look at it and tell it's an over-center mechanism. The back piece of latex tube would clearly hold it open under tension. I'm more curious about what moves the two halves far enough forward to break-over and snap shut. Is it just inertia when the middle hits the bar?

Yep!

Even if it doesn't hit a bar, the inertia of the two hooks makes them go over center when the grappler reaches the end of the rope.

Very cool.

What happens when it misses does it ever have the potential to go outside 15"?

How do you aim it?

How did you use the rubber band like a crossbow if it was inside of the pneumatic cylinder. Also could you fit under the low bar with it?

What I believe they did was use that red stick thing to push back an elastic band (probably surgical tubing), and then used the pneumatic cylinder to hold back the elastic band and keep it there until it was quickly released by actuating the cylinder.
