Many seasoned and professional miners turn to custom-made metal detectors for depth to attain levels underground that not every detector is built to reach.
While depth also comes with extra features like a high price (due to a more advanced technology used), these metal detectors are not what you use for everyday treasure hunting.
So why would you want to go deeper?
For one. If you’re taking metal detecting as a full-time indulgence and not just a hobby, you’ll need devices in the market that can search farther than the standard metal detectors would and perform tasks that conventional metal detectors would struggle to achieve.
Deepseeking detectors go beyond just search for treasures to locating pipes, septic tanks, caves, etc. They are used extensively in the mining process and also during underground construction.
Some of the features of metal detectors for depth that give them their unique ability include Operation technology, coil size, etc. The Pulse induction and Multi-frequency detectors are perfect for going to deep lengths underground. Similarly, large search coils can withstand ground mineralization for depth in locating treasure.
Let’s check out the best of them.
