What is this coil primarily used for? The 25RM excels in two areas: patch finding, and searching for large gold nuggets at depth. When exploring new country for patches it is important for a prospector to cover as much ground as possible per day.
A large diameter coil like the 25RM makes that possible by allowing more ground to be scanned in less time. Along with ground coverage, depth penetration is another area prospectors are always striving to improve. Simply put, a bigger coil equals better depth. Try out this coil on those supposedly “hunted out” patches and you might be amazed at what is hiding 2 or 3 feet beneath the surface.
If you are looking for pure penetrating power the 25RM is just the ticket!
