Coil Waterproofing: The Key to Protecting Your Metal Detector and Enhancing Your Hunt
Coil Waterproofing: A Guide for Metal Detectorists
Metal detecting is a popular hobby that requires the right equipment to ensure success. One of the most important pieces of equipment is a metal detector coil. But what happens when you accidentally drop your coil in water? This is where coil waterproofing comes into play.
Waterproofing your metal detector’s search coil can protect it from moisture and ensure its longevity. In this guide, we’ll explore everything you need to know about coil waterproofing.
What Is Coil Waterproofing?
Coil waterproofing refers to the process of protecting your metal detector’s search coil from water damage by making it water-resistant or fully waterproof. It’s particularly important for those who use their detectors near bodies of water, such as rivers, lakes, and beaches.
When Should You Waterproof Your Coil?
It’s recommended that you take precautions before exposing your search coils to water. Some manufacturers offer models with built-in waterproof features; however, if yours doesn’t have this feature, then consider purchasing a protective cover or applying sealant yourself.
If you’re planning on beach hunting or underwater detecting, it’s essential that your search coils are properly protected against saltwater corrosion and other elements found in marine environments.
How Does Coil Waterproofing Work?
There are different approaches to waterproofing a metal detector’s searchcoil:
1) Protective Covers
One option is using protective covers specifically designed for metal detector coils. These covers prevent debris from getting stuck inside the holes on the bottom of the coil and keep moisture out while allowing signals through freely.
2) Sealants
Another option is coating the entire surface of the searchcoil with sealant either by spray painting or brushing on a liquid product like Plasti Dip rubberized coating or Rust-Oleum LeakSeal flexible rubber coating.
Make sure to apply several thick coats (3-4) evenly over all surfaces including where cable enters at top collar connection joint.
Note: the sealant must be fully cured before using the coil again.
3) Waterproofing Bags
Finally, waterproof bags are another option for protecting metal detector coils. These bags can be slipped over the searchcoil and sealed with a ziplock or Velcro closure to keep water out.
The choice of method depends on personal preference and how much water your searchcoil will be exposed to. Some people prefer protective covers because they’re easy to remove, while others like the convenience of waterproof bags.
Benefits of Coil Waterproofing
Waterproofing your metal detector’s search coil offers several benefits:
1) Protection Against Moisture Damage
Moisture can corrode internal components, causing them to malfunction or fail entirely. By waterproofing your search coil, you’ll protect it from moisture damage caused by rain, splashing waves or accidental drops in puddles.
2) Extended Longevity
By preventing moisture damage, you’ll extend the life of your metal detector’s search coil as well as other components that may come into contact with water during use.
3) Enhanced Performance
Search coils that have been waterproofed properly perform better than those that haven’t received any protection. You’ll get better depth readings and more accurate target identification.
4) Versatility
Coil waterproofing opens up new areas for detecting such as beaches, shallow rivers & streams and wet grassy fields without having to worry about damaging expensive equipment.
What Are The Limitations Of Coil Waterproofing?
While there are many benefits associated with coil waterproofing, there are also some limitations:
1) Limited Depth Capability
Most detectors lose a bit of depth when submerged in water making it harder to detect objects deeper beneath soil layers without special underwater models designed for deep-water hunting.
2 ) Reduced Sensitivity
Waterproof coatings may slightly reduce sensitivity compared with bare copper wire coils which could affect detection accuracy especially when searching for small targets like gold nuggets.
3) Higher Cost
Waterproofing your searchcoil can be a bit pricey, especially if you opt for high-end sealants or waterproof bags/ covers.
Coil Waterproofing Tips
Here are some tips to keep in mind when waterproofing your metal detector’s search coil:
1) Always follow the manufacturer’s instructions before using any product on your metal detector. Some products may void warranty claims so it’s best to check first.
2) Make sure that the sealant is fully cured and dry before using the coil again. This usually takes several hours or up to 24 hours depending on the brand you choose.
3) Test your waterproofed coil in shallow water first to ensure that there are no leaks or interference with detection capabilities before going deep underwater detecting.
4 ) If possible, remove all non-waterproof items from pockets such as cell phones, wallets and car keys before beach hunting since saltwater can damage electronics.
Conclusion
Coil waterproofing is an essential step for protecting your metal detector’s searchcoil from moisture damage. Applying a protective cover, sealant, or using a waterproof bag will enhance its longevity and performance while also opening up new opportunities for detecting in wet environments.
Remember to always follow manufacturer instructions and test out new equipment in controlled situations before venturing out into deeper waters. With proper care and maintenance of your equipment, you’ll have years of successful detecting ahead!
