Panther Martin is truly the world’s ‘Classic’ spinner. It has an original concave-convex blade design that maximizes water flow over the blade to produce a unique blade rotation and flash. Panther Martin spinners have no clevis to connect the blade to the shaft. This means that each blade rotation is different and unpredictable, imitating the natural action and vibration of a variety of creatures fish feed on. Each spinner is precisely weighted and balanced to produce a combination of flash, sound and vibration fish can’t resist.
