The importance of water-resistant performance in reels cannot be overstated, especially since they are constantly exposed to seawater and endure heavy loads. A well-designed reel with effective water-resistance not only ensures durability but also enhances your overall fishing experience by preventing corrosion and maintaining smooth operation.
Experience the advanced technology of Shimano’s “X PROTECT,” designed to deliver excellent water-resistant performance without compromising the smooth rotational capabilities of your reel.
Protect your reels from Saltwater
When fishing at sea, one of the significant challenges is the harsh environment and the issue of saltwater intrusion in reels. When saltwater penetrates the reel's interior, it can lead to corrosion of the gears and metal components. This corrosion significantly diminishes the reel's initial performance, making regular maintenance and using corrosion-resistant materials essential for longevity and optimal functioning.
To prevent issues with water damage, Shimano has created X PROTECT, a robust water-resistant system designed for various spinning reels, whether small or large. This innovative feature ensures optimal performance and durability in all conditions, giving you peace of mind while fishing.
A water-resistant system like no other!
In addition to the conventional water repelling treatment, X PROTECT has also utilized a unique “labyrinth structure” to prevent water from entering. This complex labyrinth-like design, combined with the water-repelling effect, effectively keeps water from penetrating the interior of the reel.
Shimano has incorporated a specialized water-resistant system into both small and medium-sized reels that demand high rotational performance, as well as into larger reels that focus on superior water-resistant capabilities. This approach ensures that each reel type meets its specific performance requirements effectively.
Enhanced rotational performance for medium and small reels
Small and medium-sized reels, which require delicate retrieval sensitivity, demand exceptional rotational performance. Our advanced design achieves the perfect balance of high water-resistance and smooth rotation, eliminating the need for packing that could hinder performance. Experience the ultimate in handling and efficiency with our innovative reel technology!
This technology is designed for the roller clutch section, which effectively prevents the reel from rewinding in reverse. Additionally, it plays a crucial role in the line roller section, helping to straighten out any twists in the line as it is wound onto the reel.
Superior water-resistance for large spinning reels
Large spinning reels, used in tough offshore conditions, need enhanced water-resistant capabilities. To address this, Shimano has implemented a contact-type water-resistant structure. Additionally, Shimano utilizes low-friction sealing materials to effectively keep seawater from infiltrating the reel's interior. This approach not only achieves excellent water-resistant performance but also reduces resistance during the reel's rotation.
This water-resistant technology is applied in various components, such as the roller clutch and line roller, similar to what is found in small and medium-sized general-purpose spinning reels. Notably, the roller clutch section boasts water-resistant performance that is on par with IPX8 standards.
Long lasting performance
Reels equipped with X PROTECT are engineered to keep seawater out, ensuring smooth reeling over extended periods, even in challenging conditions.
These reels will become a dependable companion for anglers seeking toughness and durability in their fishing gear. With their robust design, they are built to handle the demands of any fishing adventure!

Our goal, effortless reeling.
Shimano's reel design concept aims for “eternally smooth reeling.” The result is HAGANE. Shimano honed its proprietary metal processing technologies with precision cold-forging technology and refined them over many years to develop reels that only Shimano could deliver.
Seize control with powerful reeling.
When the rod bends powerfully and you grip the handle knob to stop the target's escape, the reel's design ensures smooth power transfer, giving you the upper hand in the fight.
Shimano's INFINITYDRIVE eliminates those frustrating moments, ensuring powerful reeling even under high load. With this technology, you'll be able to land big fish that once seemed impossible to catch.
Revolutionary PROPULSION: The perfect balance of distance and tangle-free fishing.
Shimano's "PROPULSION" enhances this process by correcting the line's path, which minimizes tangles and enables impressive long-distance casting performance.
