The T400 runs Libreboot, a free and open BIOS and the Trisquel GNU/Linux OS. Both of these tools should render the Libreboot T400 as secure from tampering as can be.

Titleist’s new T400 irons will hit retail shops on March 27, and they will sell for $185.50 per club ($1,299 per 7-piece set) in steel and $199.50 per club ($1,399 per 7-piece set) in graphite.
