Busy,

Narrow's Marina is the closest unless you want to drive a little further. I live directly across from Green Pt so it is a short 3 minutes shot for me.

As far as the Black Box it has changed my fishing hook ups percentage ten-fold. All your "box" questioned can be answered at the above web page. This is not what the Scotty BB looks likes however, the principles are the same.

I've included a chart of Green Pt.

Downriggin'
