Nope, and it still doesn't!
It's a static field. It discharges a painful but entirely non-lethal jolt into things. It takes far elss power than some kill-o-zap field, and it does what it needs to; it keeps the wildlife away.
However, it is also a holofield. A... stati-holofield. It was set up to make the area look like what it did before the small base that Xeth and Denz can now see was built there.
