Tenryu Injection SP 79 H

At Gerry’s Fishing, we know that stepping up to heavy lures often comes with a trade-off: more power usually means more fatigue. The Tenryu Injection SP 80 H (often referred to by its 2.40m length as the 79 H) is the “Heavy” class rod that breaks that rule. Designed specifically for launching and animating oversized topwaters and big soft plastics, this rod provides massive “grunt” without the soul-crushing stiffness usually found in 80g-rated blanks.

The standout feature here is the Smooth Action. Tenryu has engineered this blank to be progressive; it’s powerful enough to punch a 60g surface lure into a headwind but “soft” enough in the right places to avoid the dreaded “helicopter effect.” If you’ve ever cast a long, slender soft plastic only to have it tumble in the air and ruin your distance, you’ll appreciate how this blank’s loading cycle keeps the lure stable and flying true.

Precision Power for Big Predators

This isn’t just a “winch.” The SP 79 H is a precision tool for technical big-lure fishing. When working legendary surface lures like the Patchinko 165 or Asturie 170, the rod’s action ensures you aren’t “rushing” the lure. A rod that is too stiff will rip the lure out of the water or ruin its walk-the-dog cadence; the 79 H has enough “give” to let the lure breathe, ensuring it stays in the strike zone and performs its intended action even in choppy coastal conditions.

Technical Specifications

Examples of Where to Use

• Rough Ground Bass Fishing: Perfect for when you need to use oversized surface lures to get noticed in “big water” or high-energy surf.

• Deep Water Shadding: An ideal rod for working large 18cm-25cm paddletails on 40g-60g jig heads for monster Pollack and Bass over wrecks and reefs.

• Large Estuaries & Tide Rips: Use the rod’s length and power to “bully” large lures through heavy currents where smaller rods would simply fold under the pressure.

• Specimen Pike: The progressive action makes this a fantastic crossover rod for casting large unweighted soft plastics or big jerkbaits in freshwater.

Gerry’s Pro Tip

“The 30-80g rating might tempt you to use heavy, thick braid, but to get the best out of the 79 H, I recommend staying around 1.5 to 2.0 PE (25lb – 35lb). Because the rod manages the ‘helicopter effect’ so well through its loading phase, a slightly thinner, high-quality braid will fly through the guides and add significant yardage to your cast. Also, when working those big 165mm+ surface lures, keep your rod tip slightly higher than usual—the rod’s smooth recovery will do all the hard work for you, saving your wrist for the fight!”

Frequently Asked Questions

Is this rod too heavy for standard 20g Bass lures?

The 79 H is a specialist. While it can cast a 20g lure, it won’t “load” properly. It’s designed to start performing at the 30g mark. If you’re primarily using standard 15-25g plugs, you should look at the SP 82 MH. This “H” version is for the “big stuff.”

Why does Tenryu call it a ‘Smooth’ action rather than ‘Extra Fast’?

In heavy lure fishing, an ‘Extra Fast’ (very stiff) rod is incredibly fatiguing and often results in pulled hooks or poor lure action. Tenryu’s ‘Smooth’ action means the rod has a more progressive bend. This protects your knots, makes casting large lures more comfortable, and prevents the lure from ‘tumbling’ in mid-air.

Can I use this for light tropical fishing?

Yes! The 79 H is a popular “stepping stone” rod for Mediterranean or Atlantic trips. It has the backbone to handle hard-fighting Bluefish, Barracuda, and small Amberjack, provided you don’t exceed the 80g casting limit.

Does it handle ‘Straight Tail’ soft baits well?

Extremely well. Long, straight-tail eels can be notoriously difficult to cast long distances without them spinning. The progressive load of this blank keeps the lure’s trajectory straight, maximizing your “prospecting” area on every cast.
