Black Magic 'Groper grabber' rigs are an excellent choice for fishing in the surf after dark.  The rigs are simple and consist of a two hook paternoster style rig and can be attached to the main line or shock leader strait out of the packet via a swivel (very similar to a snapper snatcher).  To the other end all you need to do is attach a sinker.  They are quite cheap to by and are made with quality components and are easy to rig up, even in the dark.

The rig is tied with a 400lb main leader with 2 X 200lb droppers which are crimped to the main leader.  A Black Magic KL wide gape circle hook with fly is attached to the end of each dropper along with a small glo bead for extra night time attraction.
