Yo-Yo's on juglines?

For those that don't know a Yo-Yo is a spring loaded set line that I think is illegal to use in Texas as such because it is a safety hazard for swimmers. Would it be legal to use them on jug lines?

No

Suppose you altered it to be nothing more than a line holding device, to not rewind when unset.

What would be the purpose of this hypothetical device?

Easy depth adjustment.

Baitsaver hooks already has a jug fishing reel: http://www.baitsaverhooks.com/bait-saver-jug-fishing-reel-patent-pending/

lol, I wonder how their patent application is coming along.

I saw the title to the thread and thought you'd seen the same guys jugging my home lake the other day! Definitely a boat load of Yo-Yo's!

Full Disclosure: They sent me some reels to try and review on my YouTube channel about a year ago. The video is up if you search for it on YT. It wouldn't be appropriate to post it here.

Honestly I didn't like the unit, as I prefer fixed depth jugs anyway. a small boat cleat would do just as well and be far more durable.

Still, the idea is commendable: adjustable depth on a reel-type unit.
