Controlling the LBV
Hold the OCU in a manner that is comfortable to you. The most common way found is with
the left hand supporting the left side of the controller with thumb on the vertical thruster
knob. Use your right hand to hold the right side with your fore finger and thumb holding the
top of the joystick.
Consider these points:
Move the joystick with a smooth motion
Do not over steer
Adjust thruster gain to suit conditions
o
Operate at the minimum gain that allows
observable progress
Use the camera angle
Relax

Thruster Gain Control
The thrusters fitted to the LBV are very powerful. They enable operation in strong currents,
deep depths and with plenty of tether in the water. Due to the power of the thrusters, the
LBV is fitted with a variable gain control. There are two separate settings for gain control;
VERT and HORIZ. These correspond respectively to surfacing/diving and horizontal
controls. The amount of power available can be anywhere from 0.625% to the full 100%.
Reducing the amount of available power to the thrusters gives the user more control of the
LBV.
When the LBV is powered up the default thruster gain is 50% showing a 5 for
VERT and HORIZ.
3.8
Trim
The Trim function holds the thruster controls automatically. When the vertical thruster or
lateral thrusters are being operated, the trim key can be pressed to hold that input.
For example: If you are descending down to 50 meters, set the down thruster gain to 100%,
rotate the vertical thruster control knob to full dive. Press the trim key, then return the
vertical thruster control knob to the center/off position. The LBV will continue to dive until
the trim key is pressed again.
