Armed Snook
Centropomus armatus
A southern Pacific snook called 'Pacific white snook' in parts of Central America — a name that elsewhere means Centropomus viridis, so use the Latin name. Its very long, stout second anal spine is the surest identification.

Casts plugs and bait past the breakers and handles stripers, drum and bluefish in the wash.
Reel · Best value
5000 size sealed spinning reel
≈ US$120-180
Salt spray and dunkings kill cheap reels — a sealed body and 30 lb braid capacity are the surf standard.

Plugs for blitzes, jigs for the trough, bait on a fish-finder rig when they won't chase — the inshore trio.
