The Spider is the integral part of the Spider Putting System. It’s made from a thermoplastic compound that’s waterproof, shock resistant and weighs less than 2ozs. When installed, the Spider lies flush on the ground over the cup or as a standalone target on the green. Steel rods and foam bumpers work to sharpen aim and guide perfect putts through the other side. Rubber bands automatically return or redirect putts for back-pain free practice sessions. When an actual cup isn’t available, the white ring is the exact diameter of the real thing to reinforce consistent target recognition.
