What makes the ET18 specifically designed for plumbing?
The ET18 uses a 5 ft (1.5 m) armored gooseneck cable rather than a flexible unarmored cable. The armor provides rigidity to push the camera through pipe bends in drain lines, cleanouts, and P-traps without kinking — critical for navigating plumbing systems where an unarmored cable would buckle.
Can the ET18 be used in drain water?
The IP67-rated camera head and cable are rated for temporary submersion in 1 meter of water for 30 minutes — suitable for standing water in drain sections, flooded cleanouts, and submerged fittings. Dry thoroughly after use.
How does the 5 ft armored probe compare to the ET17's 10 ft flexible cable?
The ET17's 10 ft flexible cable reaches deeper into wall cavities and long conduit runs. The ET18's 5 ft armored cable sacrifices depth for the stiffness needed in plumbing pipe navigation. Choose ET18 for plumbing drain inspection; ET17 for general utility, conduit, and wall-cavity work.
Does the ET18 need a phone to display video?
No — the ET18 is fully standalone with a built-in display and rechargeable lithium-ion battery. No phone connection or app is required.
What resolution and lighting does the ET18 provide?
720p resolution from a 5.5 mm camera with 6 built-in LEDs — identical specs to the ET17. The key difference between the two is cable construction (armored vs. flexible) and probe length, not image quality.
