Borehole Camera

The GeoVISION micro M3 offers color viewing and video logging in small and large diameter boreholes. The portable camera system, which is made by Marks Products Inc., will go to a maximum depth of 1,100 feet and into as small as a 1.5-inch borehole. Included with the system are a variety of lighting accessories and a compass. The different light heads and side-looking mirror attachments make the system quite versatile - you can get a view of looking down and sideways in the same picture. Marks Products Inc., Card No. 295
