Geovision Deluxe & Heavy duty winch
Up to Seven viewing modes are available with Deluxe GeoVISION™ systems • GeoVISION™ system cameras are usually lowered into the borehole viewing down. In small and moderate size bores this is adequate. When one wants to view to the side or back up the borehole, or view into a crevice or mine, there are several other choices. • Motorized Pan and Tilt option with the Jr and Standard cameras. One may view 360 degrees by panning and tilt up and down 170 degrees with the motorized pan and tilt attachment. This option allows one to view in any direction with the operation of the joystick on the control panel. • One can manually pan and tilt with the Jr and Standard cameras by using a pipe string and the GeoVISION™ supplied manual head tilting assembly. The operator can view in any direction including up by pulling on the power cable and by turning the pipe. All GeoVISION™ systems have a threaded pipe-fitting, ready for attaching a user supplied pipe string. The camera can be pushed or pulled past obstructions or pushed and pulled horizontally or overhead with a pipe string. Pipe strings can be made from many different materials. • One can rotate the side viewing camera of the Dual Scan micro. It has twenty-one high-brightness LED’s in three groups. • The Motorized Mirror for the nano camera allows one to view to the side and around in a complete 360 degrees. • An Optional Side-looking Mirror is available with the Standard and Jr cameras to allow side viewing in small diameter boreholes. • Camera Lights On-Off Circuitry- This switch allows the eight LEDs in the Stainless Steel Standard camera and the 21 LEDs in the Dual Scan micro camera to be turned on or off. Using the supplemental lights reduces glare from suspended particles in the water, increases texture of the subject, and improves depth perception by using indirect light. When the water quality is good, the built in camera lights should be turned on to provide fill light. The combination of built-in and supplemental lights achieves the best images in clear water. In most cases, the best videos are obtained by using brighter off camera lights, such as the Adjustable Super Eight Light or the Dual Scan micro camera.

The portable and lightweight GeoVISIONTM borehole under water video camera systems are used for viewing and video logging in small to large diameter boreholes. When combined with other geophysical logging you can get the whole picture.
Find and view fractures, voids, water inflow, cross or inter bed water flows, sand, gravel, grout, ground water pollution or ground water contamination infiltration.

The systems are designed to be used in vertical bores but can be used in horizontal bores by placing the camera on an owner provided skid or cart and pushing it with a plastic pipe string. The cameras can go around shallow turns but they are not designed to go around sharp turns.
All GeoVISIONTM systems output in NTSC video format, which is the standard for North America and Japan . There are several methods available to convert the signal to a different format such as PAL or SECAM.
