The "Cajun Thunder" and similar products have some super serious competition from "Low Country Lightning."
The "Low Country Lightning,"(LCL) at first glance looks a lot like the Cajun Thunder. A closer look reveals several major differences.
Instead of a thru-wire, the "LCL" uses a hollow brass tube. In the ends of the float itself, there is a brass ferrule rather than plastic. On the bottom side of the float, there are 3 solid brass beads with the one on the bottom brazed to the brass tube.
The hollow brass tube is fitted with a peg at the top end. The design of the LCL allows you to adjust the depth of your bait or lure rather than relying on a fixed depth or having to lengthen or shorten your leader by cutting and re-tying.

Lowcountry Lightning is available at the following shops in Florida.
Please note: I don't have my list with me, so I may be leaving out a few.
Amelia Bait and Tackle Amelia Island,FL
White's Bait and Tackle Fort Pierce, FL
Whitey's Sebastian Inlet, FL
Fishin' Cove New Smyrna, FL
Long Point Tackle Sebastian, FL
Those are all I can think of off the top of my head, but I will review my reciepts and list all the others. I can be reached at 843-814-9998 or lowcountrylightning@hotmail.com.
Thanks Again,
