Metal detector for large products


  • Sturdy aluminium design – particularly robust and weatherproof with short metal-free zone
  • Ideal protection for hackers and OSB flakers
  • High search performance and noise immunity through 4-quadrant technology, even better with Power Drive option
  • Maintenance-free: automatic calibration and automatic balance control
  • Easy installation and intuitive operation
  • Remote control and remote maintenance (option SHARKNET®) with documentation of all settings, metal messages etc.


CASSEL BIG metal detector for coal


The METAL SHARK® BIG with rectangular opening is specially designed for large products such as logs, bales or recycled wood. It detects iron, stainless steel, aluminium etc. precisely and reliably even under difficult conditions.

Thanks to its robust design, it is particularly suitable for industrial use on rough terrain. The typical installation is in a trough conveyor with flat belt, or in a specially prepared vibratory conveyor.
