No pic,but get a full size Bic lighter,in them there's a spring,insert through rod tip 1/4 or a little more and wrap it to your rod with tread and a little super glue.If you like better visibility dip tip of spring in white jig paint,let dry them dip in orange,let dry,them open the tip on spring with a needle(the paint clogs the spring)I have also stretched one end of the spring straight about a inch and wrapped it to my rod inside the tip.This is the best spring Bobber there is,I've used them for a long long time,the spring is way more sensitive the the frabill popper.
