Pricision made Gimbal head in Allu with 3 bearing , one in both side and one in bottom of the head
bolts in stainless steel. All tolerence no more than 1/100mm . Drilled holes to make it light.
Don´t ask for buying because component and time make it to expensive . It is not serial production but handmade. I am sure it´s better than Manfrotto (Bogen)Gimbal head.
