Joystick

The
operator moves the joystick to the first position, and the beam moves
slowly...he/she moves it further, and the beam speeds up!  Since a
separate speed dial or fast/slow switch has now been eliminated (which
requires two hands of operation), the operator can now use his/her free
hand to steer the vessel, hold binoculars or hold a firearm.

Additional
control station functions are:  Beam-ON, Beam-OFF, Electric Beam-Size
Focus, "Proportional-Speed" Joystick (described above), and a Beam-On
Indicator Light offered on control stations mounted inside, out of the
weather.
