As a veteran detectorist having used the Simplex+ over New England’s varied landscapes, from damp seashores to muddy farms, I’ve found that maintenance is key to keeping your detector in working order. Whether a weekend warrior or every day hunter, this guide will safeguard your investment and provide maximum performance in all circumstances. I’ve done metal detector maintenance guides in the past, but this one is great for Nokta Simplex+ owners.
NOTE: Nokta has released the successor to the fan favorite Simplex+ — The Simplex Ultra, with some nice upgrades and addons.
Basic Care for Your Nokta Makro Simplex+
The reality is that metal detecting is often a dirty business. After a day of trudging around in soggy fields or saltwater beaches, your Simplex+ needs a little love. Here’s what I’ve found to be most effective, be you in the damp Southeast or coping with harsh winters in the North.
Coil Cleaning: The First Line of Defense
The coil bears the brunt of any abuse. For beachcombers, exposure to salt is a particular killer – I learned that to my detriment after a weekend at the Beach. Here’s my tried-and-tested cleaning procedure:
Remove the waterproof coil cover gently (it can be resistant when sandy) and wash each side in fresh water. Clean up remaining grit using a soft cloth – I use microfiber – and allow everything to air-dry completely before assembly. This quick procedure, done every other hunt, has ensured my coil is working like new even after two years of heavy use.
Advanced Cleaning: Beyond Cleaning Basics
As winter approaches or during protracted storage, I suggest a more intense approach. Leverage the Simplex+’s modular design – unscrew the coil and separate the shafts. Be careful around connection areas where grit tends to hide.
Cleaning Accessories
Over time, you may find that you need to get a little more aggressive in tackling tough residue that’s stuck to parts or accessories such as coil covers, stalks, or pin handles.
Pro tip: I use GT85 spray (available in most bike shops) on moving parts after cleaning. As it is distinct from WD-40, it leaves a PTFE coating that keeps everything smooth and coated, helpful to detectorists in rainy areas.
Seasonal Maintenance

Essential care considerations for optimal performance
-
Coil Seal Attention
Monitor and maintain coil seals more frequently in warm temperatures to prevent degradation
-
UV Protection
Ensure proper UV protection when equipment is in storage to prevent sun damage
-
Beach Cleaning
Implement faster cleaning protocols when using equipment on beaches due to salt and sand exposure
-
Battery Ventilation
Pay special attention to battery ventilation to prevent overheating in hot conditions
-
Drying Protocol
Ensure thorough drying after use in damp conditions to prevent moisture damage
-
Cold Weather Batteries
Apply specialized cold weather treatment to batteries to maintain performance
-
Waterproofing Checks
Conduct additional waterproofing inspections to ensure protection against winter conditions
-
Temperature Control
Store equipment in controlled temperature environments to prevent freeze damage
Troubleshooting Common Problems
Having helped many Simplex+ users in our local detecting club, here are solutions to common problems:
- Unstable readings? Clean coil connection points of dirt
- Lowered depth? Check ground balance is correctly set
- DRAINING THE BATTERY QUICKLY? Clean charging contacts
- False signals? Modify sensitivity to soil conditions
Regional Maintenance Advice
Detecting in varying areas demands varying approaches to maintenance:
- Beach Areas: Additional protection from corrosion required
- Clay Soils: Clean more frequently
- Rocky Areas: Shock-absorption checks in place
- Damp Fields: Enhanced waterproof maintenance

My name is Paul and I am the founder of Detector For Metal, a dedicated resource for metal detecting enthusiasts seeking to uncover historical treasures and connect with the past using the latest technology. As a stay-at-home dad and family man, I’ve found metal detecting to be the perfect hobby that combines family adventure with historical learnings for the whole family.
As a father, I’m deeply committed to passing on this hobby to the next generation of detectorists, starting with my own children. I share advice on everything from metal detecting with kids to exploring the top 10 metal detecting sites you never thought about. My methodical approach to the hobby goes beyond the thrill of discovery—it’s about creating family traditions while preserving history and sharing the stories of those who came before us.
