Running with the elven eyeball idea, perhaps you could only use it's ability when looking through the eye. That way you couldn't have something else in your hand (e.g. a weapon) or hamper movement a bit because it distorts your vision slightly. In addition, you would probably need to be evil to create such an object given you need a preserved elf eyeball.
Eyeball of Detection
This preserved eyeball of an elf has a small hole cut in the back of it that you can peer into, and see as if looking through the eyeball. Peering through the eye you can detect secret doors, compartments, caches, and so forth. Only passages, doors, or openings that have been specifically constructed to escape detection are detectable with thsi eye. The amount of information revealed depends on how long you study a particular area or subject. You must hold the eyeball before your own in order to see.
1st Round: Presense or absence of secret doors.
2nd Round: Number of secret doors and the location of each. If an aura is outside the line of sight, then you discern its direction but not it's exact location.
Each Addtional Round: The mechanism or trigger for one particular secret portal closely examined by you. Each round you can turn to detect secret doors in a new area.
