Pinpoint and Mark Drain Location

What happens here

With the camera positioned at the desired location within the pipe (e.g., a critical junction or anomaly), begin scanning the concrete floor above with the pipe locator. Start in 'FAR' mode (up to 16.5 feet deep) to get a general idea, then switch to 'NEAR' mode (up to 3.3 feet deep) for more precision, as indicated by the user manual. Gradually reduce the locator's sensitivity using the adjustment buttons (e.g., from 'NEAR 7' down to 'NEAR 3' or 'NEAR 2') while moving the locator to find the strongest signal. The strongest signal strength and audible tone indicate the exact vertical and horizontal position of the camera head. Once pinpointed, use a permanent marker to clearly mark the spot on the concrete floor.

Goal: Use the pipe locator to precisely identify the camera's position beneath the floor, adjust the sensitivity for accuracy, and mark the exact spot on the concrete.
