Detecting on the Beaches of Sussex

 Beach Composition & Detecting Strategy

The Sussex coastline shifts dramatically from west to east, requiring you to adapt your equipment and settings.

West Sussex (e.g., Bognor Regis, Worthing, Littlehampton)

• The Terrain: Primarily flat, expansive stretches of wet sand revealed at low tide, topped by a shallow shelf of shingle (pebbles) near the seawall.

• The Strategy: This is ideal territory for pulse induction (PI) or multi-frequency VLF detectors. Wet, salted sand is highly conductive and will cause single-frequency machines to chatter constantly. Target the low-tide line for recently dropped modern coinage and jewelry, and look for “low spots” where storms have stripped the top layers of sand away to expose the heavier clay underneath.

East Sussex (e.g., Brighton, Eastbourne, Hastings)

• The Terrain: Heavily dominated by steep, deep pebble and shingle banks, broken up by wooden or concrete groynes. Sand is usually only visible at the very lowest point of the tide.

• The Strategy: Shingle is brutal on equipment. Pinpointing targets deep within shifting pebbles is incredibly difficult, and standard sand scoops won’t work—you will need a heavy-duty, reinforced trowel. Focus your energy around the base of the groynes where heavy objects get trapped by the longshore drift (the movement of sediments along the coast).

3. History & Historic Finds

Sussex beaches have been hit by everything from Roman trade to World War II defense operations.

Common Historical Finds

• Wartime Relics: Because Sussex was the frontline for potential invasion during WWII, the beaches are littered with history from the 1940s. You will frequently dig up spent .303 ammunition casings, shrapnel from anti-aircraft shells, and uniform buttons.

• The Victorian/Edwardian Boom: Beaches like Brighton, Worthing, and Eastbourne became massive tourist hubs in the 1800s. The moving shingle is a time capsule for pre-decimal coinage (Victorian pennies, silver sixpences) and lost personal trinkets like silver pocket watch keys or decorative brooches.

• Maritime Trade & Smuggling: Sussex was notorious for smuggling in the 1700s. Heavy storms occasionally scour the beaches down to the ancient clay, uncovering hammered silver coins, trade tokens, and lead cargo seals from historic shipwrecks.

⚠️ Important Safety Note on Ordnance: Because of WWII coastal defenses and bombing raids, you may occasionally encounter Unexploded Ordnance (UXO). If you dig up something heavy, metallic, and cylindrical/conical, do not clean or move it. Mark the location, clear the area, and call the Coastguard (999).

4. Tides and Weather: The “Scour” is Key

Beach detecting is entirely dictated by the moon and the weather.

• The Tides: Always consult local tide tables before setting off. The best time to detect is one to two hours before low tide, following the water line down. This gives you access to the cleanest sand that hasn’t been picked over. “Spring Tides” (which occur during full and new moons) offer the lowest retreats, exposing areas of the seabed that are normally inaccessible.

• The “Scour”: Normal beach conditions hide old targets under feet of sand. You want to look for “scouring” conditions. This happens after heavy winter storms or strong offshore winds, which physically drag millions of tons of sand and pebbles out to sea. If you step onto a beach and notice the sand level has dropped significantly, exposing dark clay, ancient peat, or rocks, drop everything and start detecting—this is when the oldest history is uncovered.

5. Facilities & Accessibility

If you are planning a full-day dig, choosing a beach with solid infrastructure makes a massive difference:
