A device for coupling to a working end of a hydrovac boom hose includes a tubular suction tube for removably coupling to the working end of the hydrovac boom hose such that an opening of the working end remains unobstructed. A plurality of high pressure turbo nozzles configured for emitting high pressure water are located around a circumference of the tubular suction tube such that the turbo nozzles surround the working end of the hydrovac boom hose to dislodge earthly materials under the device. An outer housing to enclose and protect the tubular suction tube, turbo nozzles, and onboard locating device, and to provide an air duct for ambient air to pass down threw. A plurality of air vents in the outer housing that provide flow of ambient air to an area being excavated. The conduit coupled with the outer housing, for allowing ingress of water to the plurality of high pressure turbo nozzles.
