I found it!

Thanks DS- I have some of those. I tried using them but I made my own Carolina type rigs that allow the slinker to slide. The sliding sinker seems to foul a lot less than the fixed trolling sinker. I appreciate the offer though. Thank you!

They do foul unless you get the good bead chain ones and always remove the cheap clips on the ones pictured above tie on a 3foot leader and a redgill with a 3/0 hook and drag along the bottom in a northeaster using 2 to 3 ounce trolling weight we have been doing that for over 25 years. By the way just a heads up the sand destroys flys and turns white ones brown to almost black.
