It’s not that I lock the waypoints because I don’t trust you, it’s simply for your protection……
The Furuno TZtouch3 features a Pin Code Lock that keeps your GPS Waypoints, Routes, and settings safe from being stolen. The TZtouch3 Multi-Functional Display is now as safe as your phone protecting all your secret fishing spots. The GPS chartplotter lock can’t be hacked.
