The Explorer is a single operator system for efficiently inspecting and evaluating water wells and other boreholes to 1,200 feet. The compact unit is easily set up and operated to help detect borehole integrity problems early, reducing costly and unnecessary repairs. All components, including the control unit, are mounted on a compact cart.  Manual focus and iris adjustment provide clear images in difficult lighting conditions. Two models are available with 600 feet or 1200 feet Kevlar braided coaxial cable.
