Back to main Econo Heavy Duty system page


Some Econo Heavy Duty system features include:


1.         Six Color and Ultra Low Light Black and White camera options. They are 100% solid state cameras that are small diameter, light weight and highly reliable. They have excellent light sensitivity and low power consumption.

2.         Every camera housing is pressure tested beyond its rated depth before it is shipped.  There are stainless steel screws in the housing and a brass connector for the cable connection.  The camera’s light source, eight white LED’S (Light Emitting Diodes) do not normally burn out or need to be replaced and they consume very little power.  The camera and housing together weigh less than 4 ounces.

3.         The Camera Pan and tilt attachment allows the operator, at any time, to tilt the camera head from looking straight down through looking sideways to looking 90° above horizontal (upward) by pulling up on the camera cable.  This can be done in 4” or larger boreholes, but this attachment must be used in conjunction with the owner supplied pipe string or a camera weight. 

4.         The Camera Support is designed to attach to the centralizer or the pipe string or the support clamp.  It consists of a 3/4” female, CPVC Pipe Adapter and 2 stainless steel straps. 

5.         The Support Clamp has a 3/4” male CPVC Pipe Adapter that allows attachment to the camera support or the centralizer and an acetal plastic split clamp that attaches to the main cable and 2 stainless steel support straps.  This takes the tension off of the camera connector.

6.         The adjustable camera Centralizer and/or a pipe string (see above) can be attached to the camera support’s female pipe adapter.  Use the centralizer to keep the camera in the center of 4” to 14” bores.  The nylon straps are adjusted outward so their setting is somewhat smaller than the borehole.  The straps are on an outer pipe while the pipe adapters are on the inner pipe.  This allows free rotation of the camera without rotation of the nylon straps.  Thus, material is less likely to be loosened from the borehole walls by the straps when the pipe string is turned to rotate the camera head.  The centralizer should be used with the support clamp or the owner supplied pipe string.

7.         The one meter two connector cable is used to connect the camera to the main cable when using the tilt-head attachment.

8.         The steel, heavy-duty, hand operated winch may be ordered with either 325, 650, or 1000 feet of cable.

8.         The cable is a three-conductor polyethylene coated cable with footage marked at one-foot intervals (optionally marked in meters).  The copper clad steel ground and power wires each have an average tensile strength of about 75 pounds.  The cable is used to support the camera through support clamp.  To view the picture from the camera, the operator uses an owner supplied TV Monitor, TV/VCR Combo, Eyetop monitor, or Camcorder with A/V inputs.  You may use one of the optional monitors available from Marks Products, Inc.

9.         The various components are connected to and interact through the System Power Supply.  There is a power on/off switch on the power supply box.  The system can be powered from a 115 Volts AC 60 Hz source through use of the AC power adapter or directly from a 12-14 Volts DC power source.  The other connectors on the box include, microphone in, Audio & Video out jacks.  For details on when and how to use these connectors, please see the, “Operating the System” section of this manual.

10.       Some of the optional attachments are: Cable protector, On-Screen-Depth display, 5” B/W Monitor, Ultra Low Light B/W Camera, 5.6” LCD Color Monitor, Side-Looking Mirror, Compass, Dual-Dive Light, Carrying Case, Deluxe Carrying Case, 300 watt inverter, Tripod for monitor.
