The day couldn't have been better - waves rolling in, gulls overhead, and your detector sweeping smoothly along the shoreline. Maybe you dug a few coins, some jewelry, or just enjoyed the thrill of detecting by the sea. But once you're home and unpacking, you notice it: that dark, clingy layer of sand stuck to your coil and shaft.
Don't overlook it. Magnetic sand, salt, and fine grit can interfere with your detector's performance and even cause corrosion over time. Luckily, the X-Terra Elite's waterproof design makes cleaning easy - as long as you do it correctly.
Here's how to get your detector back to pristine shape after a successful day on the beach.
1. Start with a Gentle Freshwater Rinse
The Minelab X-Terra Elite is fully waterproof up to 5 meters (16 feet) when the coil is attached. That means you can confidently rinse the entire unit - from control box to coil - under fresh water after your beach hunt.
-
Submerge or rinse the detector in cool, clean water to remove salt and sand.
-
Move the coil gently to dislodge trapped grit around seams or edges.
-
Avoid using high-pressure jets or hot water, which can damage seals.
Tip: Always rinse your X-Terra Elite as soon as possible after each saltwater outing. Dried salt crystals can become abrasive and corrode metal parts.
2. Remove Magnetic Sand from the Coil
Magnetic sand - made up of iron-rich minerals like magnetite and hematite - loves to cling to your detector's coil. Over time, it can cause false signals or mask weaker targets.
To clean it off safely:
-
Wipe the coil surface with a soft, damp cloth or soft-bristle brush.
-
For stubborn grains, use a plastic scraper (an old credit card works great).
-
If fine magnetic particles are stuck tight, use a small magnet wrapped in cloth to draw them away without scratching the surface.
Tip: Pay extra attention to the coil ears and cable entry point, where magnetic sand often hides.
3. Clean the Coil Cover (Skid Plate)
Even if the top of your coil looks spotless, the underside might tell a different story. Sand and salt often collect inside the coil cover after a beach trip.
-
Snap off the coil cover and rinse both parts thoroughly in fresh water.
-
Brush away fine magnetic particles, then dry completely before reattaching.
-
A clean coil cover helps prevent false targets and ensures optimal sensitivity.
4. Wipe Down the Shaft and Cam Locks
The X-Terra Elite's carbon-fiber shaft is lightweight and durable, but sand can still get into the cam locks and adjustment joints.
-
Extend the shaft fully and rinse it under fresh water.
-
Move the cam locks while rinsing to flush out trapped grit.
-
Dry thoroughly, then apply a light silicone or Teflon spray to keep movement smooth.
This simple step helps prevent stiffness and prolongs the life of the locking system.
5. Clean the Control Box (It's Waterproof - But Be Smart About It)
Because the control box is waterproof only when the coil is attached, never disconnect the coil cable during rinsing or submersion.
-
With the coil still attached, rinse the control box gently in fresh water.
-
Use your fingers or a soft cloth to wipe away salt and sand.
-
Once finished, dry the exterior with a microfiber towel.
Important: Never open the headphone cap or disconnect the coil while wet. Allow the detector to dry completely before removing components.
6. Let Everything Dry Completely
Even waterproof detectors benefit from good drying habits.
-
Air dry all parts in a shaded, ventilated area.
-
Avoid direct sunlight or heat sources - excessive heat can affect seals and plastics.
-
Store the detector partially disassembled to allow airflow and prevent trapped moisture.
Final Thoughts
The Minelab X-Terra Elite is built for adventure - from inland relic hunting to the surf's edge. But even the toughest detector deserves a bit of care after battling salt and sand. A quick rinse, a careful wipe-down, and a few minutes of drying can make all the difference in keeping your Elite performing like new.
Your detector found the treasure - now make sure it's ready for the next hunt.
