Overview & Specifications

The SC-350 & 500 winches are manually operated and come pre-spooled with 350ft. or 500 ft. of poly-urethane wrapped, Kevlar reinforced cable. The cable is equipped with a pre-installed cable head that facilitates connecting the winch to either the SC-166 camera or the R-CAM dual view camera.

To facilitate raising and lowering the camera, the winches include a collapsible hand crank that is located on the back of the winch. The winch also includes an interlocking, manually operated brake that allows you to hold the camera at the desired depth position.

  • Cable: 350 feet (107 meters) or 500 feet (152 meters) of Kevlar Reinforced Coaxial Cable
  • Cable Head: Detachable Laval Quick-Connect Cable Head, Pressure Rated to 5,000 PSI with Built-in Strain Relief
  • Drive: Manual Hand Crank Reel with Collapsible Handle for Maximum Portability
  • Dimensions: 17 Inches High (43 cm), 15.5 inches Wide (40 cm), 15 inches Deep (39 cm)
  • Weight: 22 lbs (10 kg) without cable.  30 lbs (13.6 kg) with 350 feet (107 m) and 33 lbs (15 kg) with 500 feet (152 m)

What Customers Say

The camera is excellent and it makes a night and day difference in our business.

Gary Shawver

I used to borrow a friendly competitor’s camera.  He had a small one with a hand reel and a tripod made of PVC.  It worked for me at times, but the R-cam 1000 is heads and shoulders above that.

I hoped we would use our new R-CAM 1000 at least 1 time per month... but we're averaging closer to 10. Plus, I don't have to subcontract the work out to my competition anymore, and I'm picking up a bunch of additional well rehab work.

Frequently Asked Questions

The downhole facing SC-166 is suitable for boreholes up to 10 inches in diameter. The R-CAM dual view camera can view boreholes up to 16 inches in diameter. The DC5150 is suitable for borehole diameters up to 30 inches in diameter. Please note, visibility downhole will be impacted by the clarity of the fluid and the available light.

Some manufacturers will claim that a wide-angle down-view lens can provide just as much viewing area as a dedicated side-view camera module. This is simply not the case. To achieve the clearest, most detailed view of the side of the borehole you will need a dedicated side-view camera. The R-CAM dual view camera and DC5150 come equipped with 360-degree side-view and dedicated down-view cameras.
When you view the system as a whole, the cable is one of the least expensive components at the time of purchase, yet one of the most difficult to upgrade at a later time. Our recommendation is to equip your system with more cable than you initially think you’ll need. A camera system will be in service for many years, and while you may only survey wells that are 500 ft. today, in seven years you may be surveying wells that are 600-700 ft. deep. Additionally, the cable will be removed periodically when replacing the cable head as a part of normal maintenance. Having additional cable is a great way to future-proof your system and ensure your peace of mind.
While a real-time video survey is preferable to having no down-hole data at all, the real value of a down-hole survey is the video data is generated and can be analyzed and reviewed at a later time. With this in mind, nearly all of our systems come equipped with state-of-the-art DVR’s that easily capture and store your video data. These videos are stored on an included 16 GB thumb drive for easy sharing with customers.
Having your depth displayed on-screen in real-time is a critical data point when conducting an underground survey. Without your depth count on screen, it is very easy to become disoriented down-hole and miss critical bits of information, like a break in the well casing. Nearly all of our down-hole camera systems are equipped with a highly accurate digital encoder, ensuring you know the exact depth of your camera while conducting a survey.

Every camera system will eventually require a repair to the cable head, the point at which the cable and camera physically connect. Over time, the internal connections within the cable head can be strained to the point where they disconnect and cause interference or a complete loss of the video signal. To expedite the repair process, we have cable head repair kits available for both portable systems and large vehicle-based systems.

Conducting surveys with the included centralizers and available lens shield accessory is the best way to ensure that the camera head remains protected downhole. When not in use, store the camera head in an area where it will be safe from unintentional drops or damage. If your camera system is damaged, we offer full repair services at our headquarters in Fresno, California.
