Reel Review

 

Shimano Tranx 300B Baitcaster - A More Refined Beast for Big Baits and Bigger Fish (continued)

 

Price and Applications: While the new Tranx 300B offers significantly better retrieve feel and handling than the previous generation not everything in the new generation is an upgrade. The new reel comes in at $349.99, about $50 more than the previous model, and also adds a touch of weight across the comparable models. The higher speed reel is also noticeably heavier than the lower speed version due to the enlarged gearing and the 7.6:1 version tips the scales at 12.2 ounces, while the 5.8:1 is 11.8 ounces.


While it would have been nice to see the new reel maintain the same weight I do feel, at least in the case of this new Tranx reel, the gains in rigidity and smoothness make it a fair trade.

 


With aftermarket handles and oversized knobs the Tranx feels custom made for slinging swimbaits

 

Also, while two gear ratios cover most needs, a slower 4.9:1 power cranking option would be welcome for deep-running the biggest plugs and A-rigs. My personal favorite 300B retrieve ratio is still the 7.6:1 reel which I find is fast enough to work topwater baits, and still easy enough to slow down for more subtle presentations, like working softbodied swimbaits in Fall and Winter.

Ratings: (We've re-calibrated our ratings standard for 2008 and have included a key at the bottom of the following matrix as a guide):

Shimano Tranx 300B Reel Ratings (?/10)

Construction/Quality Still built like a tank, just more modern. The new reel feels just as robust as the outgoing model but more refined 8.8
Performance I was a fan of the 300A Tranx, heck I still am and regularly use it to fish big swimbaits, but the new reel takes things to another level. The CoreSolid design and externally adjustable SVS Infinity MD System make this reel both a better caster and more solid feeling reel when retrieved 8.8
Price Not surprisingly, the new Tranx 300B comes in about $50 higher than the previous generation we reviewed back in 2017. Like most things, reel prices have climbed, and while it would have been nice to see Shimano hold the original price point, that’s probably unrealistic given today’s material and labor costs. Even at $349, the Tranx 300B still delivers a lot of reel for the money 8
Features The new reel doesn't grow in bearing count and even gains a little weight but it features a whole new platform with the CoreSolid body. The other feature that really improves performance is the SVS Infinity MD casting system. Other proven technologies like X-Ship, MicroModule gears, and corrosion resistant S A-RB bearings all help add up to a powerful reel that feels right at home in both fresh and saltwater applications 8
Design (Ergonomics) The new reel sits lower and feels more natural when palmed thanks to the compact CoreSolid body. It feels really good when you consider the reel's large gearing and high line capacity. The new Tranx looks like a bigger bantam from many angles, and feels like one too when cast and palmed 8.5
Application Like the previous generation, the Tranx 300B easily pulls double duty in both freshwater and saltwater environments. Everything about this reel feels purpose-built for big bait, big fish scenarios, with the power and refinement to back it up 9.5

Total Score

8.60
Ratings Key: 1 = terrible : 2 = poor : 3 = lacking : 4 = sub par : 5 = mediocre : 6 = fair : 7 = good : 8 = great : 9 = excellent : 10 = unbelievable!

Pluses and Minuses:

Plus

Minus
+ CoreSolid body dramatically increases rigidity and power transfer (and it looks better too) - Higher price than outgoing model
+ Smoother and more powerful retrieve - Slightly higher than previous generation
+ Better casting control and distance - The power handle may not be preferred by everyone (I liked it for saltwater fishing but preferred a dual knob configuration for bass fishing)
+ Improved overall refinement  
+ Better ergonomics (except weight) than previous generation  
+ Feels powerful and purpose built for big baits and battles with big fish in both fresh and saltwater  

 

Conclusion: Most of the time, Shimano doesn’t reinvent their platforms - they evolve them. Rather than starting from scratch, the company typically refines proven designs by integrating features from higher-end reels. In the case of the Tranx 300, however, Shimano went a step further. The new 300B feels like a complete refresh built around the CoreSolid formula that has already proven itself in the smaller Bantam and Metanium series. In fact, the CoreSolid design arguably makes even more sense here, providing the rigidity and alignment benefits that a larger, more torque-oriented reel truly needs.

 


The new Tranx 300B feels much more refined than the previous generation, and is a pleasure to cast and retrieve with


The result is a reel that feels more connected and planted under load, with MicroModule gearing and SVS Infinity MD braking combining to deliver exceptional smoothness, precision, and control. On the water, those upgrades translate directly into confidence—whether pulling against the raw power of bat rays in the Bay or working Delta tulle lines for largemouth bass.

 


Arguably the most improved Shimano baitcaster this season, the Tranx 300 is a beast of a reel that feels right at home casting big baits for in the hunt for big fish


After weeks of use across both freshwater and saltwater, the Tranx 300B feels like the reel the original 300A always aspired to be - tougher, smoother, and more refined. It handled everything I threw at it without flinching and has already earned a permanent spot in my lineup, particularly for targeting fall-run stripers. For anglers chasing big fish with big baits, the Tranx 300B stands out as an outstanding revolution of a popular series - and quite possibly Shimano’s most improved reel of the season, earning it our Editor’s Choice Award. Whether your target is trophy bass, stripers, muskie, tarpon, and even bat rays, this new Tranx delivers a solid blend of strength, control, and refinement - all at a very compelling price.
