When you're shopping for a thermal borescope visual inspection camera, the real question is how far you need to see and what you're willing to spend. The RIDGID CA-25 is a compact handheld with a short cable for close-up checks, while the Wohler VIS 350 is a dedicated push-rod system built for long pipe runs. The price difference is enormous, and each one excels in a different kind of job.
Quick Verdict
If most of your inspections happen around sink traps, wall openings, HVAC lines, and engine bays, the RIDGID CA-25 gives you an easy-to-justify price for close-up work. If you routinely inspect long sewer lines, ducts, or conduits and need a camera head that can look sideways at joints, the Wohler VIS 350 is the more capable tool.

Where Each Product Wins
Where the RIDGID CA-25 wins
The RIDGID CA-25 wins for close-quarters work on a modest budget. The short cable is enough to reach into drain traps, behind panels, or down a short pipe run, and the camera is easy to aim in dark spots. It also takes up far less space in a toolbox.
Where the Wohler VIS 350 wins
The Wohler VIS 350 wins for serious long-reach diagnostics. The push rod travels deep into pipe runs, and the camera head can look sideways at joints. Reporting extras help pinpoint where a blockage sits, and the display stays readable in awkward positions.
Product Notes
RIDGID CA-25
The RIDGID CA-25 is the camera to reach for when the target is nearby. Its 4-foot flexible cable and 17 mm aluminum head slip into sink drains, wall cavities, HVAC lines, and machinery, while four adjustable LED lights brighten dark spots. The 2.7-inch color display gives you a live look without needing to attach a phone. The low entry price makes it an easy pick for occasional troubleshooting. The trade-off is reach and resolution: you are limited to 4 feet of cable, and the 480 x 234 resolution is modest, so fine cracks or small details can be harder to read. This used unit is best suited for quick, close-up checks rather than long sewer runs.
Wohler VIS 350
This used system is built for long, serious inspections. The 100-foot push rod and pan-and-tilt camera head let you work deep inside sewer lines, ducts, and long pipe runs while viewing side-wall details and joints. The 7-inch monitor can be angled or removed for tight access, and the digital meter counter shows how far the rod has traveled. With the integrated locator transmitter, you can pair it with a compatible locator to pinpoint the position and depth of a blockage. The substantial investment and the bulk of the full kit make it more than a casual homeowner needs. For contractors or maintenance teams doing extensive line work, the speed and reach can justify the cost.
Final Choice by Use Case
Choose the RIDGID CA-25 if you need a portable, low-cost camera for close-up checks behind walls, in drain traps, or inside equipment. Choose the Wohler VIS 350 if your work regularly takes you down long pipe runs and you need the reach and reporting precision of a full-size system.
