ET17 provides a dedicated screen and inspection probe in one tool, which is useful when you do not want to rely on a phone for viewing. Its narrow camera head can reach through suitable openings, and adjustable LEDs illuminate the nearby inspection area. The nylon-covered cable offers reach for checking accessible cavities, while included retrieval and viewing accessories can help with specific tasks. Distinguish capture resolution from screen resolution: the camera captures 720p imagery, and the built-in display uses a different pixel count. The camera head and cable have water-resistance specifications that do not automatically apply to the complete monitor. Check access clearance, keep the cable away from moving parts and make the equipment safe before inspection.

Who this model suits
Standalone inspection without phone compatibility concerns
Important buying checks
Water protection does not apply equally to every component; access clearance matters.
- A charging arrangement compatible with the tool; a phone is not required.
Plan the complete setup
- Check the probe diameter, working distance and articulation or cable arrangement against the opening you need to inspect.
- For phone-connected tools, confirm the supported operating system, app and connector. Some products use their own screen instead.
- Thermal imaging shows surface-temperature patterns; a borescope supplies a visible view into an accessible space. Choose the technology for the observation you need.
