Antiquities threshold
Sebastian Inlet State Park sits at the geographic center of one of North America's most significant maritime treasure corridors. On July 30–31, 1715, a fleet of eleven Spanish galleons carrying silver and gold from the colonies was caught by a hurricane off what is now Indian River County. The fleet was nearly entirely destroyed — an estimated 1,000 lives were lost, and thousands of tons of coin and cargo were scattered across the ocean floor between Melbourne Beach and Fort Pierce.
On the beach itself — above the mean high-tide line — recreational metal detecting is permitted under Florida State Parks beach access rules. No detecting-specific permit is required. The ocean-facing beach on the park's south side is the primary detecting area, accessible after paying the standard entrance fee. The beach is narrow and geologically active; its character changes meaningfully after northeast storms.
The offshore wrecks are a separate legal zone — completely off-limits without a state salvage contract
The 1715 Fleet shipwreck sites in state waters are designated Sovereign Submerged Lands Archaeological Preserves under Florida Statutes § 267.061. Recovering any material from the seabed within the preserve boundaries — including the surf zone — is a third-degree felony carrying up to $5,000 in fines and 5 years imprisonment. The preserve has no visible boundary markers in the water. If your detector signals on a hard target in the surf or beyond, do not dig.
Where the beach rule ends and the preserve begins
The legal dividing line is mean high-water mark. Above it: state park territory where recreational beach detecting is permitted (subject to FL Ch. 267). Below mean high water: sovereign submerged lands. For the 1715 Fleet preserve specifically, any disturbance below that line requires a formal state salvage contract. Florida DEP and FWC enforce this boundary. The beach permit does not follow you into the water.
Best Times to Detect at Sebastian Inlet
Winter (Nov–Feb)
GoodNo turtle restrictions. Northeast storms are most frequent and most productive — storm surge strips the upper beach layer and can expose material buried for decades. The 24–72 hours after a northeast swell event, before sand redeposits, are when documented Fleet-era material surfaces. Smaller crowds midweek.
Spring (Mar–May)
FairSea turtle nesting begins March 1. Detect early morning to avoid nest interference and spring break crowds. Increased visitor losses are good for modern finds. Ocean conditions calm; fewer storm-exposure events than winter.
Summer (Jun–Aug)
FairPeak nesting season and maximum tourist traffic. Hurricane season opens June 1 — a significant storm is the defining event for this beach in any given year. Detect at first light before crowds arrive. Heat and humidity are considerable on the open beach.
Fall (Sep–Oct)
GoodHurricane activity peaks September–October. A direct or passing tropical system is the single most powerful reshaping event for this beach — detectorists who arrive within 24 hours of reopening after a storm consistently report their most significant finds. Nesting season ends October 31.
Recommended Gear for Sebastian Inlet Beach
- RequiredMulti-frequency or PI detector (waterproof to wading depth)— Saltwater sand demands PI or multi-frequency capability. Minelab Equinox 800, XP Deus II, Minelab CTX 3030 are common here. Single-frequency VLF machines struggle with saltwater mineralization and produce constant false signals.
- RequiredLong-handle sand scoop, stainless, 1/4" mesh— 1/4" mesh is important — Spanish silver cobs are thin and can slip through larger mesh. Stainless steel survives prolonged saltwater exposure; carbon fiber handles reduce arm fatigue on long sessions.
- OptionalWaterproof headphones— Wind and surf noise at the inlet mouth are significant. Wired waterproof headphones improve target separation; wireless Bluetooth introduces latency that makes pinpointing harder in wet sand.
- OptionalWaterproof pinpointer— Speeds up recovery in coarse wet sand. Garrett AT Pro-Pointer or Minelab Pro-Find 35 handle wading depth.
- OptionalField notebook or voice recorder— Document the GPS coordinates and depth of any unusual target before you dig — required documentation if you find something reportable under FL Ch. 267.

Pre-Session Checklist — Sebastian Inlet
- Check tide tables — target the hour before through 2 hours after low tide
- Check FWC turtle nest map if visiting March–October (myfwc.com/research/wildlife/sea-turtles)
- Confirm park is open — beach access may be closed post-storm pending safety assessment
- Know FL Ch. 267 — any item over 50 years old must be reported to FL DHR before removal
- Do not detect in the water or surf zone — the 1715 Fleet preserve has no visible boundary markers
- Carry a fill tool and completely fill every hole before leaving
Northeast storms produce the most historically significant beach finds in Florida
The beach at Sebastian Inlet is geologically dynamic. A strong northeast swell or passing tropical system strips several inches to several feet of accumulated sand from the upper beach face, exposing buried layers unchanged since the 1715 wreck event. Detectorists who arrive at Sebastian Inlet within 24–72 hours of beach reopening after a significant storm — before the sand redeposits — have documented recoveries of Spanish silver cobs, lead shot, and colonial ceramic fragments. Monitor Brevard County beach access announcements and go as soon as access is restored.
Permits & Licenses
| Permit | Required? | Notes |
|---|---|---|
| Ocean beach recreational metal detecting | No | No detecting permit required on the ocean-facing beach. Standard park entry fee ($8/vehicle, $2/pedestrian-bicycle) covers access. |
| State park daily entrance fee | Yes | Paid at the park entrance. Annual Florida State Parks pass ($60) covers entry. |
| Treasure salvage license (1715 Fleet offshore wrecks) | Yes | Individual hobbyist licenses are not issued. Only formal commercial salvage contracts with the FL Division of Historical Resources authorize recovery from the wreck sites. The beach detecting permit does not extend into state waters. |
Time & Seasonal Restrictions
- Sea turtle nesting season March 1 – October 31: stay 10+ feet from all marked nests; no nighttime digging on the beach
- Dunes and dune vegetation: detecting and excavation prohibited year-round under Florida coastal protection rules
- Upland park areas (picnic grounds, wooded sections, parking areas): detecting prohibited under FL DEP Rule 62D-2.014(1)(v)
- State waters offshore (1715 Fleet preserve zone): no collecting, disturbing, or recovering any material from the seabed — preserve boundary extends into and across the surf zone in some areas
- Park hours: 8 AM to sunset — no detecting outside posted hours
Equipment Notes
- Multi-frequency or PI detector required — saltwater sand is highly conductive and defeats single-frequency VLF machines
- Long-handle stainless sand scoop (1/4" mesh minimum) — required for efficient wet-sand recovery and for retaining small silver cobs
- Waterproof headphones recommended — surf and wind noise at the inlet mouth is significant
- No motorized excavation equipment permitted on the beach or in the surf zone
- GPS device or phone with coordinates — useful if you need to document a reportable find location
What People Find Here
- Spanish silver cobs (reales) — occasional beach recoveries during and after major northeast storms that strip the upper sand layer
- Gold escudos (doubloons) — rare; documented in storm-erosion events in the known 1715 Fleet zone
- Lead musket balls and colonial-era ceramic fragments — reported but uncommon
- Modern jewelry (rings, earrings, chains) — consistent after tourist season
- Coins, modern and occasional silver — regular
- Shark teeth — common in the surf zone; the Treasure Coast is rich in fossil teeth eroding from offshore deposits

- If you signal on a target in the water or surf zone, do not dig — the 1715 Fleet preserve has no visible boundary markers in the surf
- If you recover a potential colonial-era item, photograph it in-place with GPS coordinates before touching it, then contact FL Division of Historical Resources before removing it
- Respect marked sea turtle nests; walk around, not through, any flagged area
- Pack out non-target debris — cigarette butts, bottle caps, pull tabs — even if you are not the one who dropped them
- If a park ranger approaches, comply immediately; explain what you are doing calmly and show your finds

Frequently Asked Questions
Is metal detecting allowed at Sebastian Inlet State Park?
Yes. Recreational metal detecting is allowed on the ocean-facing beach at Sebastian Inlet State Park. No detecting-specific permit is required. The park charges a standard entrance fee ($8/vehicle). Detecting is limited to the beach below the dune line — upland park areas are off-limits under FL DEP Rule 62D-2.014.
Can I legally recover Spanish treasure from the 1715 Fleet at Sebastian Inlet?
No. The 1715 Spanish Plate Fleet shipwreck sites are designated Sovereign Submerged Lands Archaeological Preserves under Florida Statutes § 267.061. Recovering any material from the wrecks without a state-issued salvage contract is a third-degree felony. Individual hobbyist salvage permits are not issued — only formal commercial salvage contracts with the Florida Division of Historical Resources are available.
If I find a Spanish coin on the beach (above water), can I keep it?
No. Any Spanish colonial coin found on the beach at Sebastian Inlet is more than 50 years old and is therefore property of the State of Florida under Chapter 267. You are required to report it to the Florida Division of Historical Resources (dos.fl.gov/historical or (850) 245-6300) before removing it. Failing to report a historic item is a second-degree misdemeanor.
When do the best conditions occur for finding colonial-era items on the beach?
Storm-driven erosion events are the primary mechanism. A significant northeast swell or tropical system strips several inches to several feet of accumulated sand from the upper beach face, exposing older buried material. The 24–72 hours after beach reopening post-storm, before sand redeposits, produce the most documented Fleet-era recoveries. These events are unpredictable but recur each storm season.
Can I detect the inlet jetties or in the water?
The open ocean beach (above mean high tide) is where recreational detecting is permitted. The inlet mouth, jetties, and the water are not confirmed as open to detecting and may be within the archaeological preserve zone. Contact the park directly at (321) 984-4852 before attempting to detect any area other than the open ocean beach.
Does sea turtle nesting season affect metal detecting at Sebastian Inlet?
Yes. From March 1 to October 31, Florida's loggerhead and green turtle nesting season applies to the Sebastian Inlet beach. You must stay 10 or more feet from any marked nest and avoid any nighttime digging. Rangers patrol nesting areas. The park can restrict beach access sections around active nests.
