FAQs (Frequently Asked Questions)

Ques.1 How To Maintain An Underwater Metal Detector?

Ans- Once you are done using the metal detector, wipe it all with a cloth but don’t touch the control house. If the housing part is removable, then remove it all so it can dry properly. Once dried, remove the batteries from the control house so that they don’t leak or anything. Store it in a dry and non-humid place. These steps should be taken after each use.

Ques.2 Is There A Metal That Can’t Be Detected By A Detector?

Ans- There is only one metal that’s hard to be detected. Stainless steel is tough to be detected but not impossible. The reason is that it has poor conductivity and low magnetic permeability. Hence, it doesn’t produce a strong signal that can be detected by the underwater metal detector. Every other metal has higher magnetic permeability and can be detected easily.

Ques.3 Can I Find Gold With My Metal Detector?

Ans- That depends entirely on where you are targeting. A metal detector can detect gold buried anywhere, but it needs to be there in the first place. If you try to find gold nuggets on the beach, then you won’t have any luck. Go for areas that are generally not populated and hard to find or places with too many shipwrecks.
