While I can't add to the SAR comments all I needed to know was summed up in these few words
...and fly to airport for ILS the man's way - uncoupled...
While some might have something to prove a professional is well past the point of proving himself "the man's way" and will use all of the tools available to include coupled modes because he knows it's safer. Doesn't matter if your talking SAR, military, EMS, corporate, those tools were developed and purchased for a reason. To not use them only speaks to ignorance or ego, both of which are bad things in a cockpit.
