No worries. It's taken me awhile to get a post up myself. I'll likewise roll Perception, keeping an eye out for tails. Abran has: INT (4) + Perception (6) + Visual Spec (2) + Vision Enhancement (1) + Specifically Looking (3) = 16 dice.
Perception + Specifically Looking + Visual:
16d6t5 7Mental Limit is 5, bumped up to 6 with his Ballistic Mask. When he crosses over to more civilized areas, he'll probably need to remove the ballistic Mask, doesn't lose any Hits, but he will take another Hit to his Limit, which will make 5 for the remainder of the trip.
