M18™ 120' Mid-Stiff Modular Pipeline Inspection System for 2” – 6” Pipes (120' 10mm cable - 25mm HDR head) | (Milwaukee 3973-22)

The Milwaukee M18™ 120' Mid-Stiff Modular Pipeline Inspection System sits where most residential and light commercial work actually happens: 2" to 6" lines, 120 feet of reach. The 10 mm mid-stiff cable is the compromise that works — stiff enough to push a full run, flexible enough to get around a bend without stalling.

The 25 mm self-leveling HDR camera head with sapphire crystal lens gives you an upright, readable picture the whole way down. Pitch sensing reads the slope of the line as you go, so you can point to a belly on the video instead of arguing about it with a customer.

This is the modular generation: the reel separates from the M18™ 500GB Control Hub, so one hub runs several reels. Removable backpack straps let you carry it in hands-free — useful when the cleanout is behind the building and down a flight of stairs.

Good to know

This is the modular generation (39xx). It is not interchangeable with the earlier 29xx systems. If you already run an M18™ 500GB Control Hub, you can buy the reel on its own (3973-20) instead of the full system.
