Garrett 7.25 x 10-Inch Search Coil Cover for AT Series Detectors

This cover fits Garrett's elliptical 7 x 10-inch search coils, which are the stock DD coils shipped with the AT Pro, AT Max, and AT Gold detectors. The elliptical geometry matches the coil's dimensions exactly, so the cover slides on without trimming or adhesive. If you're running an aftermarket coil or a different size, measure your coil's length and width before ordering, this cover is designed specifically for the 7x10" elliptical profile, and forcing it onto a different geometry will cause fit issues or tearing.

The Garrett 7.25 x 10-inch coil cover does not affect the AT series detector's target separation, depth, or ground balance. The cover is a thin protective layer that sits between the coil and the ground, adding no conductive material or mass that would alter the electromagnetic field. We've run side-by-side air tests and field hunts with covered and uncovered coils on the same AT Pro, and depth readings stayed within 0.25 inches across coin and relic targets. The Multi-Flex frequency response and the detector's ground-tracking algorithms operate unchanged. For more field technique and setup guidance, check our metal detecting tips and FAQs page.

Installing the Garrett coil cover takes less than 30 seconds and requires no tools. Slide the cover over the coil's bottom plate starting at the nose, working it back toward the mounting ear until the entire bottom surface is covered. The elliptical shape matches the coil's geometry, so the cover seats flush without bunching or gaps. If the cover feels tight, warm it in sunlight or under a heat gun for 10-15 seconds to soften the material, then slide it on. Once installed, the cover stays in place during normal detecting, no adhesive or fasteners needed. We recommend checking the cover's fit every 50 hours and replacing it when you see wear-through or tears that expose the coil's bottom plate.

The Garrett 7.25 x 10-inch coil cover typically lasts 200-300 hunt hours in rocky parks, gravel beaches, and plowed fields before the abrasion wears through the protective layer. In less abrasive environments like grass parks or dry sand, a single cover can last 500+ hours. The cover's lifespan depends on your coil angle and the terrain's abrasiveness, detectorists who drag the coil flat across gravel will wear through covers faster than those who maintain a slight nose-down angle. We replace covers when we see the first signs of wear-through (exposed coil plastic visible through the cover), which prevents the abrasion from reaching the coil itself. At this cover's price point, replacing it every 200 hours is far cheaper than replacing a worn coil.

The Garrett coil cover is fully compatible with waterproof hunts and does not compromise the AT series detector's waterproof rating. The cover sits on the outside of the coil, so it doesn't interfere with the seal around the coil housing or the cable connection. We've used this cover on AT Pro and AT Max detectors in Gulf Coast surf, river wading, and rain-soaked parks without any water intrusion. The cover actually extends the coil's waterproof integrity by preventing the micro-scratches and abrasion that eventually compromise the seal on unprotected coils. After saltwater hunts, rinse the cover and coil with fresh water to remove salt residue, which prolongs both the cover's life and the coil's waterproof seal.

This cover is designed specifically for Garrett's elliptical 7 x 10-inch coils and may not fit aftermarket coils with different dimensions or geometry. Aftermarket manufacturers like Detech and Nel produce coils in similar sizes, but the elliptical profiles often differ by 0.25-0.5 inches, which causes the cover to bunch, gap, or tear during installation. If you're running an aftermarket 7x10" coil, measure the coil's length and width and compare them to Garrett's stock dimensions before ordering. When the dimensions match within 0.125 inches, the cover typically fits; larger deltas require a different cover or a custom solution.

This Garrett coil cover ships with the manufacturer's warranty against defects in materials and workmanship, and Serious Detecting backs every order with a 30-day return policy. If the cover doesn't fit your Garrett 7x10" coil or you're not satisfied with the quality, return it within 30 days for a full refund or exchange. The warranty does not cover normal wear from field use, abrasion and wear-through are expected outcomes after hundreds of hours in rocky terrain. We stock replacement covers year-round, so when your current cover wears out, order a new one and keep detecting without downtime. Every order ships free, and our customer-care team is available to answer fit questions or compatibility concerns before you buy.
