Here is the Tiagra 30; also sonic cleaned, corrosion treated. Both the Avet and Tiagra was sonic cleaned, corrosion treated, each screw corrosion treated, the drags treated with Cals grease, the mating surfaces treated with marine anti corrosive dielectric grease as was the plate which covers the drag washers as this is where galvanic corrosion sets in when there is water intrusion. Both are class acts both Avet and the Tiagras have enviable reputations for landing monster fish on the waters of the world, they are both designed and built to have the pedigree to handle whatever takes your bait in the deep blue.
