I purchased Doug Fields line of Lucky Dog trolling spoons a couple of years ago and turned them into Lurecharge spoons. All of my products have a naturally created, positive voltage field which attracts fish. Doug and I also tested his Buzzbomb/Zzinger jigs to see if enough voltage could be generated. It did turn out to be adequate and more. Doug will be testing my concept on salmon this year to see how the production is. I just debuted anode packages on my website specifically for his jigs. There are 2 anodes for different voltage levels. The lower voltage anode is drilled 3/4 through to accommodate and protect the knot. Voltage radiates from the hook as well as any exposed portions of the jig body. The second 'hotter' anode can be optionally placed between the jig and 1st anode and boost the voltage to the 1 volt range. There are pictures in the 'Anode' section of my website. I would post them here but I don't see that option. Cheers Al
