This special device is like the normal bioscanner (see there). However, it will report the natives for all scannable planets in range, not just 20% of them.
In particular, this may help you to find heavily-defended planets; those which can not be scanned by an advanced bioscanner (although they are in range) must have 20 or more defense posts.
