Shop RIDGID Compact M40 DSL SeeSnake Reels at McCally Tool and Supply. The Compact M40 DSL combines the popular compact form factor with the newest TruSense-enabled feature Digital-Self Leveling. The Compact M40 DSL has 131' (40 m) of mid-stiff push cable, providing a good compromise between stiffness and the ability to navigate turns. When used with the CS6x Versa, the innovative digital self-leveling technology produces the most stable in-pipe view, without mechanical rotation. No moving parts in the camera head improves longevity and durability, which maximizes uptime.
