Which tools are essential to bring for a duct dive?

For a duct dive, bringing a flashlight and a Teflon rod is essential. The flashlight is crucial for providing adequate illumination while working in potentially dark or confined spaces, allowing you to see clearly what you are doing and to identify any issues that might need attention. The Teflon rod is useful for tasks such as guiding or manipulating components within ducts, as it can help prevent damage to sensitive surfaces while ensuring accurate handling.

The other tools listed may be useful in different scenarios, but they do not serve the specific needs required during a duct dive. A hammer and screwdriver are generally not applicable as they are better suited for more conventional repairs rather than delicate work in ducts. Wrenches and measuring tapes are also not relevant, as the focus of a duct dive is usually on inspection and minor adjustments rather than assembly or measurement tasks. Power drills and gloves may be more appropriate for heavy-duty jobs, but again, they do not address the particular requirements of working within ducts.
