2.4.4.1  Looking for an Object

If an area of interest is found, you should set an MOB point (Marking the ROV's position, heading, attitude and depth) and mark the target with a Marker and take a snapshot. This will provide some redundancy and if you lose sight of the target, you can navigate back to the point where you know you were able to observe it before.

"A bird in the hand is worth two in the bush." It is usually best to inspect and identify possible targets when they are first observed rather than to mark numerous targets and wait until the end of the mission to go back to review them. You can easily restart the mission where you left off or by right-clicking on any waypoint and selecting Go to Waypoint or by clicking on the Skip button.

If you do return to a previously marked location and don't find the point of interest, but have high confidence you are in the correct vicinity, try to navigate the area again using a different coverage angle. The object may present a better orientation to be picked up visually, or it may be obscured by the something when approached from certain directions.
