Predator's Eye

Your eye magnifies distant targets as well as a scope. You can adjust your sight in that eye as a single action to Seek a specific creature with a +2 circumstance bonus to your Perception check, or Seek to search a 10-foot square up to 100 feet away for any undetected or hidden creatures or objects. You don't take penalties for an object or creature being too far away unless you're more than 2 miles away.
