Garrett AT Pro / AT Gold / AT Max Headphone Jack Cover

This headphone jack cover fits the Garrett AT Pro, AT Gold, and AT Max metal detectors. All three models share the same headphone jack on the control housing, and this rubber cover seals the port when headphones are not connected. If you own an AT Pro, AT Gold, or AT Max and hunt near water or in dusty conditions, keeping a spare cover in your kit protects the jack from contamination. The cover is designed specifically for these three AT Series models to maintain the detector's protection from dust and debris during use.

The headphone jack cover is necessary only when the jack is not in use. If you run your AT Pro, AT Gold, or AT Max with headphones plugged in for every hunt, the jack remains occupied and the cover stays in your parts bin. The cover becomes critical when you switch to the detector's built-in speaker for shallow-water wading, beach hunting in windy conditions where headphones are impractical, or any scenario where the jack sits open. An unsealed jack is exposed to water, sand, and other environmental contaminants that can compromise the port over time.

Installing the Garrett headphone jack cover is straightforward with the rubber design. Align the cover's tapered end with the threaded jack opening on the control housing and push it into place until it seats against the housing. To remove, grip the cover and pull straight out. Installing the cover immediately after unplugging headphones during a hunt helps protect the exposed jack from sand and water. For step-by-step maintenance guidance on all AT Series components, see our metal detecting tips and FAQs.

You should not submerge your AT Max, AT Pro, or AT Gold without the headphone jack cover installed. The cover is designed to protect the jack from dust and debris, and an open headphone jack allows water to enter the control housing during submersion. If you've lost your cover, order a replacement before your next water hunt. Running the detector on dry land without the cover installed is lower risk but still exposes the jack to dust and debris that can accumulate in the port over time.

The headphone jack cover should not affect audio quality because it seals an unused port. When you plug headphones into the jack, you remove the cover entirely, so the cover is not present during headphone use. The cover's purpose is to protect the jack from contamination when the detector runs on its built-in speaker. A damaged or missing cover allows sand and moisture into the jack threads, and that contamination can affect the port over time. Maintaining a properly installed cover when the jack is not in use helps preserve the integrity of the headphone connection.

The Garrett headphone jack cover is made from rubber material designed for repeated use in outdoor detecting conditions. Lifespan depends on installation frequency and environmental exposure. Inspect the cover periodically to ensure it remains in good condition and continues to seal the jack properly. Keeping a spare cover in your field kit provides backup protection for your detector's headphone jack. Order from an authorized Garrett dealer to ensure you receive a genuine Garrett replacement part designed for the AT Pro, AT Gold, and AT Max models.

If you lose the headphone jack cover during a hunt, avoid submerging the detector or exposing the open jack to blowing sand and water spray. The AT Pro, AT Gold, and AT Max are designed with the cover in place to protect from dust and debris, and an unsealed jack is vulnerable to environmental contamination. Finish the hunt on dry land if possible to minimize exposure. Order a replacement cover as soon as you return home to restore the protective seal for your detector's headphone jack before your next outing.

The headphone jack cover is the same part across the Garrett AT Pro, AT Gold, and AT Max because all three models use the same jack design on the control housing. This interchangeability simplifies parts inventory for detectorists who own multiple AT Series units or upgrade from one AT model to another. One cover fits all three detectors, making it easy to keep spare parts on hand. If you're unsure if a cover fits your detector, check the model name on the control housing. If it reads AT Pro, AT Gold, or AT Max, this cover is the correct replacement.
