Commercial Instruction - We offer courses in surface supplied diving.

Our team of commercial instructors is lead by Phillip E. Graf, Director of Operations. He has over 22 years of underwater inspection experience on all types of power plants and dams below the waterline. He has conducted internal pipe and tunnel inspections under conditions of zero visibility, cold water and under ice. His previous experience consists of using commercial diving equipment, principles, and techniques for inspecting major federal government water facilities in several states.

He has inspected dams and water conveyance facilities in the following states: California, Washington, Oregon, Montana, Nevada, Wyoming, Colorado, Arizona, Nebraska, Kansas, North Dakota, Oklahoma, New Mexico, Virginia, Utah, and Idaho.

Video and still underwater photography are used to document the inspections. Typical limited visibility is less than one foot. Other conditions are strong river currents and deep dives. The work in cold water (33 degrees plus) is done with the use of dry suits and diving through the ice to conduct inspections. Search patterns are implemented to locate objects and recovery techniques are used to lift objects to the surface. Venturi suction dredge/tools used to move material from stilling basins and to collect research samples. Research has been conducted on aquatic vegetation. Aquatic weeds identified and recommendations as to solutions are proposed. Endangered snails and other biological samples collected underwater and provided to researchers to identify exact species. Several research studies are monitored and data and specimens are collected. A majority of the inspection work is done at high altitudes and from metal and rubber hulled boats.
