THIS A FISHER CZ-6 LOS BANOS CALIFORNIA FACTORY METAL DETECTOR WITH SALT AND LAND MODES, ACCURATE TARGET ID,ONE OF THE PREMIER DESIGNS TO COME OUT OF LOS BANOS. I BEGAN WATERPROOFING THIS MACHINE EARLY ON BECAUSE OF ITS ACCURATE GOLD ID, AND I DIDNT WASTE TIME ON COINS. THIS UNIT IS BELT MOUNTABLE SO ALL YOU SWING IS THE SHAFT AND COIL. INTERMEDIATE SHAFT HAS TWO OPERATIONAL COLLARS. A GREAT DETECTOR AT A GREAT PRICE. I STILL USE SOME OF MY EARLY WATERPROOF CONVERSIONS.
