The GeoVISION™ Dual-Scan camera is Allegheny Instruments most advanced camera. It has three independently controlled banks of high intensity LED lights and the ability to rotate 360°. The Dual-Scan’s state of the art video modules provide unparalleled video images in bores as small as 1-1/2″ (4 cm) in diameter and to depths of 2,000 feet (600 meters).
The Dual Scan has a downview camera and a side view camera. The operator can toggle between either camera at any time, and use the joystick to rotate the view for a complete 360° scan of the borehole.
The Dual-Scan camera has standard NTSC resolution with an aspect ratio of 4:3. Illumination is provided by three banks of high intensity white LEDs which can be turned on or off from the surface. The Dual-Scan camera is rated for use up to 1,000 psi and can only be used with the Deluxe winch.
Features both Down-View and Side-View cameras with instant toggling for comprehensive inspections.
Precise 360° rotation controlled via joystick allows for detailed analysis of borehole walls.
Equipped with 3 independent banks of high-intensity LEDs for optimal illumination in any condition.
