Once the rut starts the bulls can move a long way, so identifying a specific bull this time of year will not help. Moose are big and black so they don't like to be out in the summer heat much, so scouting early can be discouraging. They will become more active in the fall but summer scouting can be good for learning roads and the lay of the land.
I hunted 26 many years ago but found it was really good to stay mobile and cover lots of ground. If you find cows, a bull may be lurking near by. I saw my bull the day before the hunt opened, but he vanished for a few days. I kept checking the cows that he was with before the hunt and sure enough, he showed back up...just in time for a dirt nap.
If you can, you might check with locals and the game biologist on where to begin looking.
