Fly Reel Test

Fly Reel Test
How can I retract a grappling hook line?

I am trying to find a way to cast out a grappling hook attached to a 50' long, 5/32" diameter paracord line (tested at 550 lbs.) and make it so I can reel it back in to a circular thing at my side. Fishing reels won't work, and I'm pretty sure fly wheels are just the same. All I want to do is throw it out, and be able to crank it back in, and be able to neatly store it like that, but be able to cast it out again without having to take out the length I need. Something that works like a fishing reel, but can hold that size of rope. Can anyone help me? Thanks!
Yeah, to make it clear, I want the retractor to fit on my belt - I've looked into winches, and it doesn't work for me. Also, it needs to be able to be casted while still rolled up. If that's impossible, I can take out the length first, but its preferable.

Cave divers use what you're describing so they don't get lost. Here's one link but you would have to call to find out which ones attach to a belt.
