So I have been playing since before TDB... and I only just recently noticed that Ghost looks at the items in the game world he wants you to scan. So if you ever get that notification and you just can't seem to find what you're looking for just pull out your trusty Ghost and he will tell you where it is and not just with that extra grid thingy it does in the pulse scan but he will physically look in the direction of the object. Blew my mind how did I miss this for so long? Just another Destiny Mind Bomb.
