Climb into our sub with visible seams and front-opening hull, control the sub with a 2010 Logitech F710 controller ($29) in Bluetooth 3.0 mode (underwater) with KontrolFreek™ FPS thumb grips that I found in my basement!

Our state of the art submarine runs Windows 10 Home Edition, no mechanical controls! Fly by wire!
