The HER line carries a crew of two explorers or surveyors, and mounts a variety of surveying tools and sensors to assist its crew in assessing newly discovered environments. It is fast, can negotiate almost any terrain, carries armaments and defenses sufficient to combat wildlife (or light infantry) who might threaten explorers, and with the aid of mass effect technology it can survive up to seventeen hundred standard atmospheres of pressure.
Newer models feature significantly increased speed and armor, greatly increasing their chances of survival against armed threats. As a result, many have been repurposes as military reconnaissance drones.
