Posted on Sep 18, 2025
By Okuma® Staff

For years, the Okuma Convector series has been a trusted workhorse for trolling anglers across freshwater and saltwater fisheries. Known for its reliability, smooth operation, and no-nonsense performance, the Convector has earned a place on countless boats. Now, Okuma is raising the bar with the all-new Convector B Series Line Counter and Level Wind Reels. A complete redesign that takes everything anglers loved about the originals and makes it even better.
Built on a Stronger Foundation
The Convector B Series starts with a refined frame and side plate construction that enhances rigidity without adding unnecessary weight. The improved design minimizes flex under heavy loads, meaning you get more power transfer and a smoother fight, especially when battling hard-pulling salmon, trout, walleye, or striped bass.
Advancements Over the Previous Generation
Okuma engineers listened to angler feedback and made key upgrades that hardcore trollers will appreciate:
-
Refined Gear System – Larger, stronger gears for improved torque and smoother cranking under heavy pressure.
-
Enhanced Drag Stack – New Carbonite drag washers provide greater surface area for consistent, powerful drag performance that won’t overheat during long runs and help to reduce drag-creepage under heavy trolling load.
-
Updated Line Counter Mechanism – More precise readings for accurate lure depth presentation, helping you stay in the strike zone longer. Also moving the reset button to the side instead of the top helps to reduce accidental resets when on the go.
-
Improved Ergonomics – A redesigned handle knob and crank system deliver better grip and comfort during all-day trolling sessions.

Line Counter and Level Wind Precision
Whether you’re slow-trolling for trophy lake trout, pulling planer boards for walleye, or chasing kings at Buoy 10, precision is everything. The mechanical line counter gives exact line deployment every time, while the level wind system ensures perfect line lay, reducing tangles and improving casting performance when needed.
Versatility Across Fisheries
The Convector B Series was designed with a wide range of fisheries in mind:
-
Freshwater Trolling – Walleye, lake trout, salmon, and steelhead.
-
Inshore Saltwater – Striped bass, rockfish, and other coastal species.
-
Specialty Applications – Great for dipsy divers, lead core, and wire line setups.
Built for the Long Haul
From the upgraded corrosion-resistant components to the rock-solid internal construction, these reels are built to withstand season after season of abuse. The Convector B Series is a testament to Okuma’s commitment to continuous improvement, blending proven reliability with the latest reel technology.
