The 11 x 8.5-Inch Footprint: More Ground, Less Separation

The appeal of the Garrett ACE 11 x 8.5-inch coil is simple: it covers a wider patch of ground with each sweep than a smaller coil. That can be useful when you have long strips of turf, broad field lanes, or open beach sections to work through.

A larger coil is not automatically better everywhere. Its wider search area can include more than one metal object at a time. In clean ground, that is usually not a problem. In a busy picnic area or old home site full of nails and iron, it can make signals less distinct and slow recovery.

Where It Makes Sense

  • Open parks with relatively clean turf
  • Farm fields and open relic sites
  • Dry sand with room for long, even sweeps
  • Large lawns, sports-field edges, and open paths
  • Sites where targets are scattered rather than tightly packed

Where It Loses Its Advantage

  • Dense trash around picnic tables, bleachers, and play areas
  • Iron-rich old home sites and cellar holes
  • Woods with roots, brush, rocks, and uneven ground
  • Tight curb strips and narrow spaces around landscaping
  • Small-target hunting in heavily contaminated ground

The 11 x 8.5-inch shape is a middle ground between a compact coil and a truly oversized search coil. It offers broader coverage without turning every hunt into a struggle around brush, benches, or narrow trails. Still, it needs space to work well.

Coverage Comes First

Choose the Garrett ACE 11 x 8.5-inch coil because you want to cover open ground efficiently, not because you expect it to solve every detecting problem.

A larger coil can reduce the number of passes needed to cover a field or park section. That matters when you are gridding a large area and want to keep your pattern orderly. Rather than rushing, use steady sweeps and overlap each pass enough that you are not leaving strips of untouched ground between them.

Keep the coil level and close to the surface. Lifting the coil at the end of a swing creates uneven coverage and makes the outer part of each sweep less useful. Shorter, flatter swings are usually more productive than wide arcs that rise above the ground.

On clean grass or dry sand, the wider footprint is a benefit. In trash, it becomes a compromise. More objects under the coil can mean more blended responses and more time deciding whether a signal is worth digging.

A smaller coil remains the better choice when target separation matters more than coverage.

How It Changes Your Hunting Style

The Garrett ACE 11 x 8.5-inch coil rewards a controlled pace. It is not a reason to swing faster or walk more quickly through a site.

With a wider coil, slow down enough to hear separate responses. Cross-check a promising signal from more than one direction before digging. If a signal changes sharply when you turn ninety degrees, nearby trash or iron may be affecting the response.

A practical routine looks like this:

  1. Sweep at a steady, comfortable pace.
  2. Keep the coil low and level.
  3. Overlap your passes rather than leaving wide gaps.
  4. Re-scan promising targets from another direction.
  5. Use a pinpointer after opening the plug or moving sand.

A pinpointer is especially useful with a larger coil because it speeds up recovery once the target is in the hole or loose soil. The coil finds the target area; the pinpointer helps narrow the final location.

Best Uses: Parks, Fields, and Dry Sand

Open Parks and School Grounds

This coil fits large grassy spaces where you can make long, uninterrupted sweeps. Open lawn between sidewalks, sports fields, mature trees, and older park features can be a better match than crowded picnic areas.

Avoid using it as your main coil in places packed with bottle caps, pull tabs, foil, and shallow aluminum. Those sites often reward the tighter target separation of a smaller coil.

Farm Fields and Relic Ground

Open fields are one of the clearest reasons to use a coil of this size. When vegetation is low and there is room to grid carefully, broader coverage helps you work a larger area without constantly changing direction around obstacles.

Rocky ground needs more care. Do not drag or pry with the coil housing. Let the coil skim the surface where possible, and use a digging tool rather than pressing the coil edge into the soil.

Dry Beach Sand

Dry sand gives the Garrett ACE 11 x 8.5-inch coil room to cover broad lanes efficiently. Search patterns around towel lines, walkways, entrances, and volleyball areas can benefit from a wider sweep.

Use a sand scoop rather than a hand digger. A scoop is faster in loose sand and leaves the area cleaner after recovery.

Tight Woods and Old Home Sites

This is where a smaller coil is usually easier to manage. Roots, branches, rocks, and iron force shorter sweeps, and the broader coil has less room to use its coverage advantage.

Old home sites can also contain nails, wire, and other iron debris close to desirable targets. A smaller coil gives you more control around those targets and is easier to maneuver along foundation lines, brush, and uneven ground.

Swing Comfort and Recovery

An 11-inch coil sits farther from your body than a compact coil, so balance matters during longer hunts. Keep the lower shaft only as long as needed for a comfortable stance. An overly extended shaft makes the coil feel heavier and encourages you to lift it at the end of each sweep.

Set the arm cuff so the detector rests securely without requiring a tight grip. A relaxed grip helps you keep the coil level and makes long, slow sweeps easier to maintain.

Recovery can also take a little longer with a broader coil. The initial signal covers a wider area than it would with a compact coil, particularly in uneven ground. That does not make the coil difficult to use, but it does make careful pinpointing more important.

For turf, cut neat plugs where permitted and recover targets cleanly. For sand, use a scoop and flatten the area after filling the hole. Fast recovery matters because the time saved while sweeping can disappear if every target takes too long to locate.

Compatibility Matters

The Garrett ACE name alone is not enough to establish a coil match. Coil fit depends on the exact detector model, connector arrangement, wiring, and electronics.

Before mounting the Garrett ACE 11 x 8.5-inch coil, match it to your specific ACE detector version. Do not assume that another coil with a similar shape or size will use the same connector or operate correctly with your machine.

When fitting a coil:

  • Align the connector carefully and do not force it.
  • Route the cable along the shaft with enough slack for full coil movement.
  • Keep the cable from rubbing against sharp edges or digging tools.
  • Secure the coil so it sits level when the detector is adjusted to your height.
  • Avoid wrapping the cable so tightly that shaft adjustments pull on the connector.

The wording matters when identifying this coil. Use the full 11 x 8.5-inch measurement rather than relying on shortened names or similar-looking coil sizes.

Basic Care

Sand, soil, and moisture are hard on connectors and cable ends. Brush loose grit away before disconnecting the coil, especially after beach hunts. Keep digging tools separate from the coil and cable during transport so sharp edges do not press against them.

If you use a coil cover, remove it periodically and clean out trapped sand and soil. A cover can protect the bottom of the coil from abrasion, but grit left inside can rub against the housing over time.

Water use needs the same care. A coil’s use around water does not automatically mean every part of the detector setup can be submerged. Treat the coil, control box, cable connection, headphones, and battery compartment as separate parts of the setup.

Who Should Choose It

The Garrett ACE 11 x 8.5-inch coil suits detectorists who regularly hunt larger, cleaner areas and want a wider sweep without moving to an extreme coil size.

It is a good match for hunters who:

  • Spend time in open parks, fields, and dry sand
  • Prefer methodical gridding over working tight trash
  • Have room for long, level sweeps
  • Use a pinpointer to speed recovery
  • Want one coil aimed at covering broad areas

It is less suitable for hunters whose regular sites are packed with iron, bottle caps, aluminum, roots, or dense brush.

Who Should Skip It

Choose a smaller coil instead if your usual hunting involves:

  • Nail beds and iron patches
  • Old home sites with dense target masking
  • Picnic areas and playground edges
  • Tight woods and root-filled terrain
  • Narrow curb strips and landscaped spaces
  • Small jewelry in heavily contaminated ground
  • Long hunts where swing comfort is the top concern

A smaller coil will not cover open ground as quickly, but it is easier to maneuver and better suited to separating nearby targets.

Mistakes to Avoid

Do not swing faster simply because the coil is larger. Fast sweeps can make target responses harder to sort out, especially when trash is nearby.

Do not lift the coil high over grass or uneven ground unless you have no alternative. Keep it as close and level as conditions allow.

Do not use the coil as a digging probe. Prying, scraping, and pressing the coil against the ground can stress the housing, mounting area, and cable.

Do not buy this coil as a cure for heavy iron masking. Wider coverage helps in open ground; it does not replace the tighter control of a smaller coil in crowded target zones.

Bottom Line

The Garrett ACE 11 x 8.5-inch coil is best for open, cleaner ground where covering more area matters more than separating closely packed targets. Its wider footprint gives it a clear role in parks, fields, and dry-sand hunting, provided you use slow, level sweeps and recover targets carefully.

For heavy trash, iron, tight woods, and small-target work, a smaller coil is the better tool. This Garrett ACE 11 x 8.5-inch coil makes the most sense as an open-ground option, not as an all-site replacement for a compact coil.

FAQ

Is the Garrett ACE 11 x 8.5-inch coil good for beginners?

It can be a good fit for beginners who hunt open lawns, fields, or dry sand. It is less forgiving in dense trash, where several nearby items may fall beneath the coil at once. Beginners who mainly hunt busy parks or old house sites may find a smaller coil easier to learn with.

Is this coil better for parks?

It is better suited to larger, cleaner park areas than crowded picnic zones. Open turf, sports-field edges, and long walking routes give the wider footprint room to work. Trash-heavy sections are usually better handled with a smaller coil.

Does a larger coil replace a smaller coil?

No. The two sizes serve different jobs. The Garrett ACE 11 x 8.5-inch coil is for covering open ground, while a smaller coil is better for tight terrain and closely packed targets.

Do I need a pinpointer with this coil?

A pinpointer is not required, but it can make recovery faster and cleaner. It is particularly helpful after digging a plug or opening a sand hole, when the wider coil has identified the general target area.

Will it fit every Garrett ACE detector?

No. Coil compatibility depends on the exact ACE model and its connection system. Match the coil to your specific detector version before mounting it, and never force a connector that does not align properly.
