Shimano Speedmaster 16 II Conventional Round Reel SPM16II

Big Capacity, High Stakes: The Shimano Speedmaster 16 II Conventional Reel

When you're heading offshore, "enough" is a dangerous word. You want more than enough—more line, more drag, and more durability. The Shimano Speedmaster 16 II (SPM16II) is the big-brother response to the 12-size, offering increased capacity for anglers who target hard-fighting pelagics and deep-water residents.

The extremely durable and high-performance Speedmaster II SPM16II boasts a high maximum drag power combined with a smooth, ultra-wide range of drag adjustability to make it a true fish-fighting machine. Whether you're chasing yellowfin tuna or winching big groupers off a wreck, this reel is engineered to bridge the gap between "capable" and "unstoppable."


2-Speed Versatility for Every Battle

The "II" in SPM16II signifies Shimano's high-performance two-speed gear system. This allows you to shift gears instantly to match the rhythm of the fight:

  • High Gear (5.7:1): Retrieve an impressive 42 inches of line per crank. This is critical for clearing lines during a hookup or staying tight on a fast pelagic running toward the boat.

  • Low Gear (3.1:1): Drop into low gear for pure, high-torque winching power. This 3.1:1 ratio allows you to maintain steady pressure on a stubborn fish without exhausting yourself.


Built for Extreme Pressure: The HAGANE Body

Offshore fishing subjects reels to immense torque that can actually "twist" cheaper frames. Shimano constructed the Speedmaster II with a rigid HAGANE Body to prevent the misalignment of moving parts under the heaviest loads. By using a highly rigid metal frame, the reel protects the internal gears from shock and ensures that every turn of the handle translates directly into pulling power.

Advanced Fishing Technology:

  • 40 lbs of Max Drag: The SPM16II delivers a massive 40 lbs of stopping power. Combined with the Cross Carbon Drag system, you get a smooth, consistent payout even at the highest settings.

  • Monofilament Optimized: Shimano includes a spare drag lever specifically for monofilament lines. This allows you to change the drag curve to better suit the stretch of mono, making it a favorite for tournament billfishing.

  • S-Compact Body: Despite its high line capacity, the reel features a compact palming side plate. It feels significantly smaller in the hand than its specs suggest, allowing for all-day comfort.

  • S A-RB Bearings: Shielded Anti-Rust Bearings are built to survive the brine. Shields on both sides keep salt and sand from ever reaching the internal rotation.


Why Choose the 16 Over the 12?

While the Speedmaster 12 and 16 share many traits, the 16-size is the clear winner for capacity-intensive fishing.

  1. Big Tuna & Wahoo: When a fish is known for 100-yard blistering runs, the extra line on the SPM16II provides a necessary safety net.

  2. Deep Dropping: If you are fishing in several hundred feet of water, the 16 allows for heavier braid and deeper reach while still leaving enough line on the spool for a fight.

  3. Heavy Braid/Topshot Combos: It is the ideal size for anglers who prefer running heavy braid (80lb+) with a long fluorocarbon or mono topshot.
