Heading
Heading is displayed at the top middle of the Video Overlay (4). The three digits
illustrate the 360 degrees of a compass heading. To the right of heading is a + or a -.

Turns counter
This is the turns counter which represents the number of turns the LBV makes in one
direction of 360º (5). The + indicates turns in the clockwise direction and the – indicates
turns in the counter clockwise direction. This is a valuable tool which allows the operator
to keep track of the turns placed in the tether. The operator should reverse these turns
(at depth) before recovery in order to facilitate coiling and prevent damage to the tether.
2.2.1.5
Depth
Below the heading information is depth (10). Depth is displayed in terms of meters sea
water (msw), meters fresh water (mfw), feet sea water (fsw) and feet fresh water (ffw).
To change the display and calibrate, see the Menu section (page 28, section 2.3.4.3).
A “*” will appear next to the heading or depth if the corresponding Auto function is on.
