The longer-reach version of Laval's ultra-portable SC line, pairing the same compact SC-166 camera with a hand-operated winch spooled with 500 feet of Kevlar-reinforced cable. Includes the control console, 7" color monitor, and auxiliary power cable — still light enough to carry to the wellhead by hand.
Water well inspection, vertical shaft surveys, and borehole documentation where a bit more reach than the SC-350 is needed, in boreholes from 2" to 10" in diameter.
