Deep-Water Yo-Yo Technique

The 4/0 excels with the classic deep-water yo-yo retrieve. Drop it to the desired depth — or straight to the bottom — then retrieve with a quick, steady winding pace that gives the jig its signature erratic swimming motion. The heavy weight punches through current and keeps the action tight even 150 feet down, and the larger profile creates more visual presence for fish keyed in on bigger bait. For a full breakdown of retrieve speed, rod angle, and hookset timing, see our Complete Iron Guide.

Pair It Like the Regulars Do

Ask any longtime SoCal iron fisherman and you'll hear the same combo: 45 on top, 4/0 on bottom. Run the lighter Tady 45 Surface Iron for shallow, surface-feeding fish, and switch to the 4/0 the moment fish drop deep or stop showing on top. Keeping both in the bag covers you from the kelp line to 150 feet down. Looking for something in between? The mid-range Tady A2 Iron and all-around Tady AA Iron fill the gap, and the Tady TLC Iron is purpose-built for trophy white seabass on deep structure.

How to Rig It

Pair the 4/0 with a stout jigging setup capable of handling both the drop and a hard hookset at depth — the Daiwa Outrage XV Slow Pitch Jigging Rod is a proven match. Run 40–60 lb Seaguar Blue Label Fluorocarbon Leader to stand up to abrasion on deep structure, and keep your whole iron collection organized and tangle-free with a Mustad Jig Pouch.

Built for Trophy Deep-Water Fish

Whether you're working deep-water yellowtail on offshore banks and high spots, chasing tuna holding below the surface, fishing seamounts and current-swept structure, or dropping deep on a Baja trip when fish won't come up, the 4/0 delivers. It's a staple for the Cedros Island run and any trip where Channel Islands white seabass and yellowtail are holding deep. New to iron fishing?

FAQ

How much does the Tady 4/0 Yo Yo Iron weigh?
Approximately 5.9 oz, with a 5.75" length — the heavy end of the Tady lineup, built specifically for getting down fast in deep water.

What's the difference between the 4/0 and the Tady 45?
The 4/0 is heavier and larger, built for dropping deep and yo-yo retrieves. The lighter Tady 45 is built for surface presentations when fish are feeding on top. Many anglers carry both and switch based on where the fish are holding.

What line and leader should I use?
Most anglers run 40–60 lb fluorocarbon or mono leader over 50–65 lb braid, sized up from typical surface iron leader to handle abrasion from deep structure and bigger fish.

What's the best retrieve speed?
Fast and steady. Drop to depth, engage the reel, and wind quickly and consistently — the heavy weight and profile create the erratic kick on their own. Slowing down or pausing mid-retrieve is the most common reason anglers miss strikes on the yo-yo.

What colors work best?
Mint Silver, Blue White, and Chrome are proven all-around choices. Scrambled Egg and Mint White produce well when fish are keyed in on sardines, and Glow White is a go-to in low light or for white seabass fishing deep structure at night.
