Really useful for cruisers would be cheap price, reasonable quality
night vision. I don't buy $300 or $700 binocs and wouldn't consider
those $$$ for night vision either. I see Harbor Freght has one at $69

See my comments in Alt.Saling.Asa and read reviews on Amazon. I'm using a under
$200 Night Owl that works very well.
