Lifeguard Duty {From the SHIV Guide)
There have been many questions about how to perform Lifeguard Duty and hopefully with the aid of some screenshots you will be able to get a better idea on what to do.
Once you have reached the area where you have been assigned to pick up the aviators. The symbol will look similar to the screen below.
Once you get close to the symbol on the map go the bridge station and using the binoculars start scanning the ocean ahead of you lookout for telltale puffs of pink smoke such as below. One thing to take note of is that the aviators may not be in the immediate area of the yellow lifeguard symbol because they may have drifted off with the current which might be prevalent in the area where you are supposed to rescue the downed aviators. You may have to scan the area quite closely to pick them out.
As you get close to the pink smoke you will see through the binoculars a man looking like he is dangling from a parachute, only you won't see the parachute. Then down on the taskbar you will see an icon with a life preserver on it.
Once you are close enough the life preserver will light up, click on the life preserver and you should get notification that the aviator has been rescued.
