Wow, this putter blows the previously mentioned Star Trek putter right out of the water as far as geek factor is concerned.
At $899, it costs more than most people’s entire set of golf clubs but for the uber-rich out there, why not pick one up? What the hell, huh? Might as well.
It uses a "micro Inertial Navigation System (INS)" to "identify the putter face position in relation to the ball at impact and display the information immediately on the vibrant color LCD." It can then relay information to you about the tempo, path, speed, and hand vibration levels of your putts.
Sadly, it’s not USGA approved.
