I'm taking a high school class and my group is trying to design a lure retriever that works better than others. Anyone have any thoughts?

I use a paper clip for the connector.

Are you talking about a plug knocker or a pole?  

 

As far as a plug knocker goes, I've done a tad of personal R&D on these on my own.  My personal plug knocker has a PTFE sleeve, so it slides better.  It's also more hydrodynamic than some of what's currently out there.  I like it because it travels faster through the water to strike the lure with more force than a lot of others can.  It also has detachable chains, which can help to snag treble hooks.  But sometimes those get in the way.  So being able to remove them is a nice feature.  I do which is held closer to the line and didn't hang so far below it, however.  But I haven't experimented with the height, so I don't know if that would make it better or worse.  It's literally made from found parts.  My number one goal in it's design was that it be free (to me).  

Retractable dog leash with a heavy weight and chains to get the lure back.
