Dry sand is easy for almost any detector, but wet salt sand and the surf are conductive and make single-frequency VLF detectors chatter. Multi-frequency and pulse induction detectors handle salt far better. Go after storms and at low tide, use a long-handled sand scoop with holes sized for your finds, choose a waterproof detector rated for how deep you wade, and check local beach rules first.
Beaches are full of modern losses and occasional old coins. Salt water changes how detectors behave.
Zones
| Zone | Ground | Detector |
|---|---|---|
| Dry sand | Non-conductive | Any detector |
| Wet salt sand | Conductive | Multi-frequency or PI |
| Surf and shallow water | Conductive, moving | Waterproof multi-frequency or PI |
Gear
| Item | Notes |
|---|---|
| Waterproof detector | Rated for your wading depth |
| Waterproof headphones | Wireless audio often fails underwater |
| Sand scoop | Long handle for water, holes sized for small rings |
| Waterproof pinpointer | See pinpointers |
| Finds pouch | Separate trash from treasure |
Timing
Low tide exposes more beach. Storms strip sand and reveal older layers. Watch for rip currents and never turn your back on the surf.
Etiquette and rules
Fill every hole, pack out trash and check local regulations; see laws and permission. Turn in valuable finds where local law requires it.
Compare technologies in VLF vs multi-frequency vs PI. Browse by ground.
Common questions
What is the best type of detector for the beach?
Multi-frequency or pulse induction, which handle wet salt sand and water.
When is the best time to metal detect on the beach?
At low tide and after storms that move sand, exposing older layers.
Is metal detecting allowed on beaches?
Often, but rules vary by town, state park and federal land. Check before you go.
What does waterproof to 5 meters mean?
The detector can be submerged to that depth. Wireless headphones may not work underwater, so check headphone ratings too.
