The Anti-Interference series is unique to Coiltek. These coils are used in regions around the world where there is high interference from power lines, salt lakes and other environments that cause electro-magnetic interference.
“Wow! I hunted directly under power lines with my 14” Anti-Interference coil and was able to recover targets that other Minelab GPX users had passed by due to the interference. In fact, most had passed up at the immediate site completely due to the interference”. - Butch Holcombe
