A heavy metallic frame on the Bionik 702 full mallet putter head surrounds an integrated lightweight thermo-plastic urethane (TPU) insert. This head has enhanced perimeter weight that provides a high MOI to prevent twisting and for great forgiveness.
The softer insert gives a muted feel and sound at impact. The main body you see at address acts as an effective alignment guide with bold sight lines that direct you to your target. The 702 has a plumbers-neck style offset to position the hands ahead of the putter.
