Grid Navigation Options
The diver enters the water, pointed toward the beach, and uses the
START
function to begin the survey. The Leg Directional Indicator
(see
“Leg Di-
rectional Indicator,” page 25
) gives the diver the position of Cobra-Tac in
reference to the beach. For navigational aids, the Diver Navigation Indica-
tor (see
“Diver Navigation Indicator,” page 24
) and pitch/roll are also dis-
played and updated in real time.
