Peerless adjustability
According to the Thunnus generation of spinning reels, the unit is the most efficient live bait spinning reel available on the market, delivering unparalleled adjustability so that you can fish any bait in any condition, even when the weather is bad. It provides the incredible smooth stopping power for which the current generation of Thunnus reels is renowned, and it does so with ease. Carbon Interfusion is denoted by the abbreviation CI4 in the product name, and the number ‘4′ represents the number of electrons carried by the carbon atom in the product. The use of reinforced carbon fiber in this model indicates that the reel is more than 12 times stronger than the brand’s standard XT-7 graphite while also being more than 20 percent lighter in weight, as demonstrated by the manufacturer’s certification.
Because there is no metal in the construction of this fishing reel, it is resistant to rusting and corrosion. As a result of all of the weight reduction and strength improvements, an incredibly light reel with extremely precise tolerances is produced.
Impressively smooth stopping power
This fishing reel, which boasts smooth stopping power, is also equipped with Shimano’s Paladin Gear Durability Enhancement, which increases the durability of the gears. This particular technology makes use of a special cold forged aluminum drive gear as well as a hardened brass pinion gear, which allows the fishing reel to retain its smoothness out of the box for a significantly longer period of time than previously. The fishing reel is constructed of a combination of metals that is significantly stronger than a drivetrain entirely made of stainless steel, as demonstrated by tests.
Efficient propulsion line management
This fishing reel, in addition to featuring Shimano’s smooth operation, also features the company’s effective propulsion line management technology, which makes use of the company’s new propulsion spool lip design. When compared to a standard spool lip design, this innovative technology has undergone thousands of casting tests and computer simulations to ensure that it can deliver longer casting distances than a standard spool lip design. All of this is accomplished while effectively limiting the formation of annoying backlashes and wind knots. When you cast, the line smoothly winds off the spool in smaller loops, which ensures that slap on the stripper guide is reduced to an absolute minimum. The propulsion spool also employs a long stroke design, which results in an increase in the distance and style of your casts as a result.
Trouble-free performance
The Thunnus CI4 will provide you with years of longer distance casting and trouble-free performance on every cast. This combination of factors, when combined with the significantly reduced weight, virtually eliminates fatigue. In particular, this fishing reel from Thunnus is intended for free lining live bait along the gulf coasts and eastern seaboards. It is expected to become an integral part of tomorrow’s stronger, lighter, and more powerful technical fishing systems.” A lure weight ranging from 12.7 to 27.7 ounces can be used with this lure weight. This model has a high number of bearings (6 + 1), which ensures that it is free of bird’s nests and that it performs consistently smooth loading and unloading operations every time it is used.
Instant anti-reverse
This fishing reel is equipped with Super Stopper II anti-reverse technology, which employs a one-way bearing configuration to eliminate back play and ensures that the reel does not reverse. As a result, the angler has access to instant hook setting power. As an added bonus, this piece of gear is equipped with stainless steel ball bearings that have undergone the A-RB treatment process, which makes them at least ten times more corrosion resistant than standard stainless steel ball bearings. Additionally, the bearings on this unit require less maintenance and spin at a faster rate because of their no-shield design, which allows for easy debris removal and easy oiling. Because of this, lubricants with a lower viscosity are required to reduce friction and allow the bearings to spin for a longer period of time while maintaining a higher speed.
