Lighter hooks bend. Heavier ones are overkill for the job. This REEF 4-prong sits in the middle — 8 mm prongs that bite into rock or coral and stay put when the current shifts. Hot-dipped galvanised coating handles the salt without flaking. Prongs arrive straightened, so you clip it on and go. No bending, no fiddling at the waterline
