The NeuFinder4 (NF4) is the latest in a series of instruments to measure the bending characteristics of golf club shafts. It is available as do-it-yourself plans as well as in kit form and pre-built units (both coming soon).

The NF4 allows you to do shaft flex matching, calibrated shaft measurement, bearing based spine finding, differential deflection based spine finding, shaft profiling and more.
